SHEETMETAL AND BENDING MACHINERY

EML-AJ SERIES, PUNCH/FIBER LASER COMBINATION MACHINE

Equipped with advanced punching- and laser cutting functions to achieve high-speed and high-quality

processing with uninterrupted operation

AMADA is the first manufacturer in the sheet metal processing industry to succeed in developing punch/laser

combination machines. They are all-in-one machines capable of integrating multiple steps for processing sheet metal such as cutting, punching, forming and tapping.

They offer two series of punch/laser combination machines – the LC-C1AJ Series of compact machines, which is capable of energy-saving, low-cost process integration and the ACIES-AJ Series, which features v-mix, v-lot production, uninterrupted operation and high-quality punch processing. These combination machines are highly rated by customers. To compliment these technologies, AMADA has launched the EML-AJ Series combination machines capable of performing high-quality punching and laser cutting and displaying enhanced comprehensive capabilities featuring high productivity and many automated features for uninterrupted operation.

EML-AJ Series combination machines come with all of the punching functions inherent in single-function punching machines. Combined punches and dies are supplied with a Z-turret with different diameters of 1010mm upper and ø1200mm lower or a high capacity turret of ø1200mm upper and lower. These machines include the same punching force of 300 kN as AMADA’s best-selling EM Series turret punch presses. The EML-AJ Series also achieves a 25% improvement in stroke frequency (number of hits per minute) compared to conventional machines, making it the fastest punch processing machine available from AMADA.

With the EML-AJ Series, AMADA has improved the quality of the laser beam with a 3kW fiber laser oscillator combining high oscillation efficiency with new optics. It employs assist gas rectifying technology for higher quality processing than conventional machines, while increasing cutting speed by a factor of three. The series also features an energy-saving operation, with power consumption reduced to one-third that of conventional machines.

The EML-AJ Series allows up to 24 hours of continuous operation by combining a wide range of optional automation solutions, such as automated Punch and Die Changer (PDC), nozzle changer, laser scrap unloading device and a cleaning function for cutting plates. As a result, customers can build a system to meet their needs with uninterrupted operation.

Main features of the EML-AJ Series

• Fiber laser cutting processing function – delivering high productivity, high quality and low running costs

In a fiber laser cutting process, this series can reduce the height of dross (residual melt attached to a cut edge) by approximately 50% and improve the surface roughness of a cut edge by 1.3 times*1, as well as achieve three times faster cutting*2, while reducing power consumption to one-third of conventional machines.

When the punching and laser cutting process are performed simultaneously, the EML-AJ Series is twice as productive with a 50% cut*2

in running costs compared to conventional machines.

*1 In the case of SPCC (Cold strip steel sheet) of t3.2 mm

*2 In the case of SECC (Electric galvanized steel sheet) of t2.3 mm

• Punching function – improved stroke frequency when punching small diameter holes

When punching small diameter holes (ø31.7mm or less), the EML-AJ Series can improve the stroke frequency by 25% compared to conventional machines by optimizing the control method of the servo motor drive allowing high-speed punching and a significant improvement in productivity.

• Improved productivity with an advanced automatic tool changer

Models equipped with an automatic Punch and Die Changer (PDC) have undergone an evolution to allow automatic replacement of tools in the processes of loading materials while laser cutting allowing high actual operation rates and further improvements in productivity. In addition, the model supports AMADA’s original ID tooling and can manage individual tools. As a result, the tool life can be monitored to improve the quality of punch processing and prevent setup errors that can occur when manually changing tools.

AMADA ENSIS LASER TECHNOLOGY

Amada ENSIS laser technology features unbelievable cutting capabilities, quality, efficiency and

cost effectiveness. It has turned laser cutting into “laser processing”, thanks to the optimal beam manipulation capabilities that manipulate the mode shape according to material thickness being processed.

Simply put, a sharp mode is suitable to thin sheet processing, while a flatter mode is suitable to thick material processing. Standard machinery all work with a happy

medium shaped mode which is set for both thin and thick cutting. Amada’s ENSIS is now capable of adjusting this mode shape automatically to the best suited shape for the material thickness being processed. This simply results in a far superior cut quality and higher processing speeds. An example of this is the capability of piercing a 25mm plate in one second on the 9kW ENSIS.

ENSIS technology has now also been incorporated into the RI (Rotary Index) – pipe cutting / flat sheet cutting laser – ENSIS

3015-AJ(RI). This 3kW laser offers the best of both worlds with the conventional flat sheet shuttle table system as well as the rotary pipe index system all in one machine. The award winning system has proven itself the world over with its CO2 power source, so the ENSIS fiber source can only capitalize on that reputation. Simple new features such as the probe feeler for pipe centering also make operation far more efficient, especially where raw materials are of inconsistent quality. ENSIS is available with a 3kW, 6kW and 9kW power option.

Additional features which are standard on the ENSIS all add to the efficiencies, such as the free roller bearing table to allow easy sheet positioning on the cutting table, Oil shot to prevent spatter build up, WACS (Water Assisted Cutting System) to reduce the thermal effect of cutting, automatic nozzle cleaning – ensuring consistent cutting head capacitance for non-contact processing, X Axis conveyor, and the Amada AMNC 3i control which shows “Real time’ part drawings as well as many other standard features.

ENSIS systems are very forgiving when processing with air as an assist gas. Again, reducing gas costs considerably due to the reduction in oxygen and nitrogen consumption.

Additional streamlined processing options available from Amada are automation options which are all fully retro-fitable to the equipment. Sheet manipulators (MPL) or a tower system (ASF) allow for material storage and the automatic loading/unloading of sheets or cut parts from the machinery. This results in a further saving of labour and consistent work flow, as the systems can run un-manned. Job scheduling ensures that the correct jobs and quantities are processed in order of preference and a full history is held for future reference if required. The advantage is now that small batch runs are possible from various lots of materials. Automatic nozzle changing further enhances set up or change over speeds.

For more information, please contact Amada – Tel: 011 453-5459.

The Ensis Series is a revolutionary advancement in fiber laser cutting

technology. The high-speed fiber laser cutting system has the ability to cut thin

materials up to 4 times faster than a CO2 laser.

The Ensis 3000 fiber laser resonator contains a variable beam control unit that

automatically adjusts the laser beam’s properties to process a wide range of

material thicknesses.

BYSTRONIC XPERT PRO PRESS BRAKEWith Industry 4.0 being a major trend in modern fabrication and manufacturing, it is more essential than ever that all equipment items in the production line have balanced capacities, and are able to operate in a coordinated network.

Bending is an essential function in many engineering and industrial processes and the necessary

equipment has to match customer requirements precisely. The new Bystronic Xpert Pro range provides manufacturers with precise bending solutions which offer consistently high bending quality.

A new press brake is a substantial investment and for this reason versatility is key. The Xpert Pro ticks this box, as it is able to carry out extended production runs and then easily switch to the production of an individual component.

Contemporary bending requirements are furthermore complex and for this reason Bystronic offers customers an extensive selection of bending tools. However, Bystronic also reduces complexity through simple machine programming and state-of-the-art CAD/CAM software.

The latest Xpert Pro is available in the Classic, Performance and Dynamic editions, which allow customers to select a press brake suited to both their requirements and their budgets. The specifications are as follows

– classic edition: maximum speed, 7.8in/sec. Maximum working speed, 0.393in/sec, performance edition: maximum speed,

8.8in/sec. Maximum working speed, 0.787in/sec. and dynamic edition: maximum speed, 9.8in/sec. Maximum working speed, 0.984in/sec. It is available in a range of bending pressures from 100 tons to 1000 tons, with bending length starting at 3.1m to a generous 10.2m length.

Bystronic’s Xpert Pro press brakes continue to offer unmatched precision. The dynamic crowning with patented pressure reference technology allows for the system to adjust the curvature of the lower beam automatically during bending. This state-of-the-art tech-nology effects corrections in real-time, making use of cutting-edge sensors which provide all required information to the press brake controller, so that automatic corrections can be made without disrupting production.

For fast, error-free bending, Bystronic’s ByVision Bending user interface offers intuitive ease of operation. A touchscreen allows for the fast processing of both individual orders and extensive order lists. What is more, it is possible to programme off-line and then import the data into ByVision Bending without disrupting current production.

Introduced at EuroBLECH 2018, Bystronic has also enhanced the Xpert Pro press brake to create the fully automated Bending Cell. The Bending Cell enables users to handle both short and long production runs – and changing order levels – efficiently and without errors and now enables automation of jobs that previously had to be performed manually. This includes automated tool changes and the transition between jobs which now enables the Bending Cell to operate autonomously 24/7.

RAPID PANEL BENDING WITH THE NEW TRUBEND CENTER 7030

The new TruBend Center 7030 bends parts up to 30 percent faster than its predecessor – and its tool change

cycles are up to 70 percent quicker. For the first time, TRUMPF has also included the option of equipping the panel bender with a loading and unloading station. Panel bending machines such as the TruBend Center 7030 are particularly adept at fabricating complex parts with radius bends, short side lengths, and narrow profiles. When it comes to producing parts with these kinds of specifications, this alternative bending technology is quicker than die bending machines. TRUMPF has focused on making the TruBend Center 7030 faster than ever. The engineers achieved this by splitting the machine’s drive unit into two parts. Instead of equipping the machine with just one central hydraulic cylinder, the new design features one cylinder on the left, and one on the right. That increases axis velocity, and boosts the machine’s productivity. The new on-demand servo drive also saves energy by only running the motor when the machine actually needs it.

Automated loading and unloading

The operator can stack various piles of metal blanks on the right-hand side of the machine. A suction cup initiates the automated loading process by picking up a sheet whilst simultaneously checking that it has not taken two by mistake. This gripper device deposits the blank on a brush table, with a positioning bar ensuring it is aligned correctly. A loading carriage then moves the blank into the machining area, simultaneously removing the most recently bent part from the machining area, and transporting it to a conveyor belt. During this loading and unloading process, the TruBend Center 7030 continues to operate.

Change tools faster – program parts within a matter of seconds

The task of changing bending tools is handled by the ToolMaster. As well as increasing its axis speed, the TRUMPF engineers have also added a feature that allows it to change multiple small tools at the same time. These improvements reduce machine setup time by up to 70 percent. The new TruBend Center 7030 also features the offline TecZone Fold programming solution that enables operators to program many parts in just a few clicks of the mouse. TecZone Fold takes a matter of seconds to generate the bending program and 3D simulation of the parts, including collision monitoring.

For more information, please contact Retecon – Tel: 976-8600.

The latest generation of the TruBend Center 7030 bends parts up to 30 percent faster than its predecessor. This boost in speed stems from its new drives and other features.

The new TruBend Center 7030 can optionally be equipped with an automated loading and unloading station.

The Durma HDF/HDFL 3015 fiber laser machine features a rigid stress-relieved welded steel frame construction with a stiff gantry axis system moving the cutting head. Highly accurate parts even when cutting with fastest speeds and under highest accelerations are guaranteed.

For more information, please contact Spectrum Machine Tools – Tel: 011 865-4090.

DURMA FIBER LASER FOR INNOVATIVE SOLUTIONS

An integrated shuttle table maximizes productivity and minimizes material handling times. The shuttle table

and pallet change system allows convenient loading of new sheets or unloading of finished parts, while the machine is cutting another sheet inside the working area. The available shuttle table is fully electric and maintenance free; there are no hydraulic oils to handle and table changes are fast, smooth and energy-efficient.

An optional lateral automatic scrap conveyor allows the removal of scrap pieces from the working area without the need to interrupt the cutting process. The sideways operation of the short conveyors allow for easy maintenance and trouble-free running.

The Durma HDF/HDFL 3015 fiber machine achieves highest dynamics and fastest laser processing cycle times thanks to the combination of rigid mechanics and a state-of-the-art numerical control and drive system. Programmes can be loaded easily into the machine with a USB stick or over a fast Ethernet connection with the company network.

In the high-pressure auto-focus cutting head for the fiber laser the cutting lens is shielded from the laser process by an

Durma HDF/HDFL 3015 Fiber Laser.

exchangeable low-cost protection window. The 1µm wavelength light is very sensitive to dust or other contamination produced in the cutting or piercing process, therefore the cutting head is being well protected in an additional cover to ensure that all critical parts remain as clean as possible.

The integrated capacitive distance sensor is capable of having the head follow height differences in the sheet even at the extreme high cutting speeds that can be achieved with the fiber laser technology, while state-of-the-art linear motors promote accuracy and increase productivity.

The CAD/CAM software provided has all the tools to import or draw parts, prepare and optimize automatically different geometries for the laser cutting process and make efficient nests.

The all-solid-state fiber laser technology reduces maintenance requirements, and offers the lowest possible running cost with a wall-plug efficiency of 30% and without the need of any laser gas. When the application requires a broader spectrum of material types to be cut and the maximum thickness range is limited, the fiber laser is the ideal solution and it will cut faster at lower cost than any CO2 laser at the same laser power.

NewsInternationalNASA’S RECORD-SETTING OPPORTUNITY ROVER MISSION ON MARS COMES TO ENDOne of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.

The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm

blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity, to no avail. The solar-powered rover’s final communication was received June 10.

“It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars,” said NASA Administrator Jim Bridenstine. “And when that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration.”

Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity

vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.

“For more than a decade, Opportunity has been an icon in the field of planetary exploration, teaching us about Mars’ ancient past as a wet, potentially habitable planet and revealing uncharted Martian landscapes,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “Whatever loss we feel now must be tempered with the knowledge that the legacy of Opportunity continues – both on the surface of Mars with the Curiosity rover and InSight lander – and in the clean rooms of JPL, where the upcoming Mars 2020 rover is taking shape.”

The final transmission, sent via the 70-meter Mars Station antenna at NASA’s Goldstone Deep Space Complex in California, ended a multifaceted, eight-month recovery strategy in an attempt to compel the rover to communicate.

“We have made every reasonable engineering effort to try to recover Opportunity and have determined that the likelihood of receiving a signal is far too low to continue recovery efforts,” said John Callas, manager of the Mars Exploration Rover (MER) project at JPL.

Opportunity landed in the Meridiani Planum region of Mars on Jan. 24, 2004, seven months after its launch from Cape Canaveral Air Force Station in Florida. Its twin rover, Spirit, landed 20 days earlier in the 103-mile-wide (166-kilometer-wide) Gusev Crater on the other side of Mars. Spirit logged almost 5 miles (8 kilometers) before its mission wrapped up in May 2011.

From the day Opportunity landed, a team of mission engineers, rover drivers and scientists on Earth collaborated to overcome challenges and get the rover from one geologic site on Mars to the next. They plotted workable avenues over rugged terrain so that the 384-pound (174-kilogram) Martian explorer could maneuver around and at times, over rocks and boulders, climb gravel-strewn slopes as steep as 32-degrees (an off-Earth record), probe crater floors, summit hills and traverse possible dry riverbeds. Its final venture brought it to the western limb of Perseverance Valley.

“I cannot think of a more appropriate place for Opportunity to endure on the surface of Mars than one called Perseverance Valley,” said Michael Watkins, director of JPL. “The records, discoveries and sheer tenacity of this intrepid little rover is testament to the ingenuity, dedication, and perseverance of the people who built and guided her.”

The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004) by the rover’s front hazard-avoidance camera as the rover moved

farther into Endurance Crater in the Meridiani Planum region of Mars. Credits: NASA/JPL-Caltech

NewsInternationalTRUMPF BENEFITS FROM E-MOBILITY

High-technology company TRUMPF is benefiting from the auto industry’s shift toward e-mobility. At the recent Automotive Photonics technology conference in Ditzingen, auto industry representatives presented the very latest e-mobility

technologies and manufacturing methods. One of TRUMPF’s key contributions is a new laser that is better suited to welding copper than any other laser – a key development driven by TRUMPF laser specialists as part of the company’s e-mobility strategy. Regarded as the most important material for conducting electricity, copper plays an essential role in the e-mobility sector. The new laser offers a more efficient means of welding copper for applications such as the high-power electronic systems used in electric cars. “The transition toward e-mobility offers some major opportunities for German industry,” said Christian Schmitz, head of the Laser Technology division at TRUMPF, at a press conference held during the technology conference. “The important thing now is to rapidly address the new areas of business and technology that are emerging from this structural transformation.” TRUMPF expects further growth for its own business as a result of the change in the automotive industry. The company’s sales of products and solutions that are channeled straight into e-mobility have doubled compared to figures for the previous year. “Twenty percent of our order intake from the auto industry is now coming from e-mobility – that’s twice as much as last year,” Schmitz says.

TRUMPF has supported these structural changes in the auto industry as a pioneering force in its specialist field, building up a worldwide network of experts entirely dedicated to e-mobility. As well as adapting part of its product and technology portfolio to the demands of e-mobility, the company has also simultaneously embarked on a series of new development projects. “The fact that we have succeeded in shifting our focus to e-mobility in such a relatively short space of time is primarily due to our decades of experience in the high-tech sector and our specific expertise in the auto industry,” says Schmitz. One example has been TRUMPF’s success in transferring its knowledge of battery pack technology and manufacturing from the medical devices sector to e-mobility.

On top of the existing auto industry, plenty of other players are also entering the automotive market, including disruptive start-ups from all over the world, Chinese companies and new companies from various fields, predominantly in battery manufacturing.

“We have the products, technologies and manufacturing expertise we need to equip all these companies with e-mobility solutions, both existing industry players and market newcomers. We already have development partnerships with traditional automakers, and we’ve been involved in the development process at key start-ups from the very beginning. In terms of up- and-coming companies from China, our years of technology experience have made us a sought-after partner in the field of battery manufacturing,” says Schmitz.

NewsLocalENCOURAGING PERFORMANCE FOR METALS AND ENGINEERING SECTOR PROJECTED TO CONTINUEDespite 2018 being a generally challenging year for both the global and domestic economy, the Metals and Engineering (M&E) sector is poised for a third annual consecutive growth in 2019.

This is according to the Steel and Engineering Industries Federation of Southern Africa (SEIFSA), who

recently released its authoritative State of the Metals and Engineering Sector Report for 2019-2020.

Given the auspicious performance of the M&E cluster of industries in recent years, this year’s Report was published under the theme of Sharpening the saw – continuously improving industry activity and competitiveness.

SEIFSA Chief Economist Michael Ade said the Federation’s forecast is for the entire M&E sector to expand moderately by 1.8% in 2019. However, the various sub-sectors will register varied levels of growth, with some expanding and others contracting in 2019.

“The prognosis aligns with the outlook for both a moderating global growth and domestic growth in 2018, underpinned by a slowdown in the pace of recovery in commodity exporters, deceleration of growth in commodity importers, a slowdown of growth in global goods and industrial activity during the first half of 2018 and the imposition of broad-based tariffs by the United States on steel and aluminium imports. These developments have serious implications for the growth prospects of the M&E sector, which exports the bulk of its iron and steel products,” said Ade.

Prices of most metals weakened in 2018, largely due to concerns about the effects of tariffs on global growth and trade, with industrial metals particularly responsive to these concerns, given their many uses in the manufacture of tradable goods. However, the expectation is for metal prices generally to stabilize in 2019 and 2020, thereby strengthening exports and improving growth prospects for commodity exporters – including the M&E cluster of industries – along with enhanced capital inflows.

However, this view is not without downside risks. These include the persistence of trade tensions, diminishing industrial activity, softening of international trade and investment and substantial financial market pressures on some large emerging market and developing economies (EMDEs). Ade said that trade tensions between the US and China, including the imposition of tariffs on an array of products, have had varying effects on metal and agricultural commodities. He said the tensions, which affected roughly 2.5% of global goods trade and had implications for South Africa, continue to remain elevated.

Ade said tighter external financing conditions – which contributed to significant capital out-flows and more significant currency pressures in more vulnerable EMDEs, including South Africa – have the propensity of increasing

external borrowing costs and the general cost of doing business, also negatively affecting production and foreign fixed investment into the sector.

“To confront this increasingly difficult en-viron ment, the most urgent priority is for EMDE policymakers to prepare for possible bouts of financial market stress and rebuild macroeconomic policy buffers as appropriate. Equally importantly, policy makers have to foster stronger potential growth by boosting human capital, removing barriers to investments and promoting trade integration within a rules-based multilateral system,” said Ade.

He said that despite these downside risks, the M&E sector’s moderate growth prospects in 2019 are influenced by the positive growth prospects for key industries which are important markets for the M&E sector’s intermediary products and are crucial in the sector’s value chain. The performance of the domestic economy, which is forecast to grow at 1.3% in 2019 and 1.7% in 2020, supported by continuous improvement of regional markets in Africa, would also impact positively on the sector’s growth prospects.

According to Ade, Sub-Sahara Africa is envisaged to improve moderately in 2019 (3.4%) and in 2020 (3.6%), providing a basis for more exports from the M&E sector. It was likely that this would translate into continued exports, bringing in much-needed foreign currency. This was especially so given the fact that Africa is the highest export destination for goods produced by companies in the M&E cluster.

Ade said that 2018 was yet another better year for the M&E sector as it expanded for the second consecutive year, registering an improved estimated annual growth of 2.0%, despite facing serious structural headwinds, including a technical recession in the broader economy. The momentum was expected to continue in 2019.

Ade said notwithstanding continuous constraints to the current potential to improve on margins in the M&E sector, all indications are that the sector will record another increase in growth during 2019, barring any major disruptions to production

“Given the recent resilience in production in the M&E sector, despite companies facing domestic headwinds, a need exists to ensure that the sector remains attractive by directly reducing increasing intermediate input costs and managing borrowing costs in order to improve consistently on the bottom line, exists,” Ade concluded.

NewsLocalSEIFSA AWARDS FOR EXCELLENCE 2019

The Steel and Engineering Industries Federation of Southern Africa (SEIFSA) invites companies

operating in the metals and engineering sector to submit their entries for the 2019 SEIFSA Awards for Excellence – which are open to all employers in the sector, including those which are not members of SEIFSA.

Now in their fifth year, the annual SEIFSA Awards for Excellence were born out of the need to encourage growth and celebrate excellence in the metals and engineering sector. The Awards offer a wonderful opportunity for companies operating in this crucial sector to receive well-deserved acknowledgement and respect by industry peers for their capabilities, expertise and innovation.

“In the current tough economic conditions, we at SEIFSA believe that it is critically important for those companies that excel at what

they do to get the acknowledgement and recognition they so richly deserve,” SEIFSA Chief Executive Officer Kaizer Nyatsumba said.

Entrants will be assessed on their performance in the period July 1 2017 to December 31 2018 in seven different categories, namely:

• The Most Innovative Company of the Year, which will be awarded to a company that showed the best level of innovation in research and development or production in 2018;

• The Health and Safety Award of the Year will be offered to a company with the best legal compliance record in Health and Safety or the lowest Lost- Time Injury Frequency rate in 2018;

SEIFSA WELCOMES PRESIDENT RAMAPHOSA’S INSPIRING SONA

The Steel and Engineering Industries Federation of Southern Africa (SEIFSA) welcomes President Cyril

Ramaphosa’s inspiring State of the Nation Address. SEIFSA Chief Executive Officer Kaizer Nyatsumba said the President’s speech was both rich in content and much welcoming of the important role that business plays in the country.

“After nine frustrating years of terrible leadership, during which the Government had a very hostile stance towards business, it feels very good to be able to say that South Africa has solid leadership again. We are very encouraged by the President’s grasp of the serious challenges facing South Africa and more importantly, his acknowledgement of the obvious fact that the Government alone does not have all the answers to the country’s problems. We are very encouraged by the

fact that he understands that all stakeholders have an important role to play and that he places such a welcome emphasis on the need for a meaningful partnership with business, Nyatsumba said.

He said like other business organizations, SEIFSA – which is part of the manufacturing sector – stands ready to partner with the Government in an effort to grow South Africa’s economy. “We hope that the President will ensure that his Ministers also come to the party.”

In conclusion Nyatsumba said the Federation commended the President for his war on corruption and fully shared his desire to see the country’s law enforcement agencies rigorously prosecuting all those who have been implicated in State capture and other forms of corruption and malfeasance.

NewsLocalSA GOVERNMENT PRIORITIZES INVESTMENT IN THE MINING SECTOR AND MINERAL BENEFICIATION

The Minister of Trade and Industry, Dr Rob Davies says the South African government has prioritized

investment and mineral beneficiation due to its capacity to grow the economy and create jobs. Minister Davies was speaking at the South African Mining Investment Roundtable that took place on the margins of the Mining Indaba in Cape Town.

The purpose of the roundtable which was organized by the South African government was to provide potential investors from targeted countries with the opportunity to interact with the South African political and business leadership in order to obtain first-hand information on the issues relating to the South African mining environment. Investors from various countries including Canada, United States of America, India, Japan, China, Saudi Arabia, Australia, United Kingdom and Russia attended the roundtable.

“The beneficiation of our minerals is one of the most critical issues that we as government have prioritized because value-addition will go a long way in creating jobs and growing our economy. We can no longer afford to export raw minerals so that they can be beneficiated in other countries. Beneficiation increases the value of our minerals and if we are stuck on exporting raw minerals we will not be able to build an economy that will enable us to create jobs and develop our country and the continent in general,” said Davies.

He added that there were opportunities for investment in the beneficiation of the South African minerals and invited investors attending the session to take advantage of them.

“As a department we are engaged in various initiatives that are aimed at adding value to our minerals. There is a variety of beneficiation projects that offer opportunities for investment,” said Davies.

He listed the development of hydrogen fuel cell-powered busses and vanadium batteries as some of the initiatives aimed at beneficiating South African minerals. The Minister of Mineral Resources, Mr Gwede Mantashe and the Minister of Science and Technology, Ms Mmamoloko Kubayi-Ngubane also addressed the session.

Mantashe spoke about the deepening of stakeholder relations between government, business, labour and communities and the opportunities the policy certainty provided by the mining charter. Kubayi stressed the importance of technology and skills and developing a sustainable mining sector.

Meanwhile, Exxaro Resources Limited committed to investing R20 billion in Limpopo and Mpumalanga, while Vedanta Zinc International committed to phase 2 and to conduct a feasibility to develop a zinc smelter in the Northern Cape.

JO’BURG TO HOST DOYENS IN AFRICA’S PVP SECTOR

The largest and most comprehensive African trade show dedicated to industries involved in the

conveyance of liquids, gases and slurries will in June bring together key buyers, engineering professionals, leading manufacturers, suppliers and agents to exhibit, network, learn and do business.

INDUTEC Africa recently announced that for the first time ever, its 11th edition of Pumps, Valves & Pipes Africa, taking place 11-13 June, will now be co-located with African Construction Expo and Totally Concrete Expo – both part of the Big Five portfolio of construction events under the umbrella of dmg events .

Says Project Manager, Nico Loretz: “The event will feature and showcase latest technologies and innovations in pump, valve and pipe manufacturing, engineering, installation, maintenance, refurbishment and all else related.”

According to Sales Manager, Dale Magaya, leading manufacturers, suppliers and service providers for pumps, valves, pipes and all related equipment within the following industry sectors will exhibit at the event:

Extractive industries (mining and minerals), construction (infrastructure), energy (oil, gas and petrochemicals), water and wastewater, power generation (solar thermal, hydropower, nuclear, geothermal), agriculture, food and beverage and pulp and paper.

Loretz adds that the event will not only feature a trade exhibition, but will also include a free-to-attend joint keynote session, workshops and interactive panel discussions that will provide practical, applicable knowledge sharing – not only for visitors to gain knowledge and improve their skills, but also to expand their professional network for years to come.

“Africa has enormous growth potential in all the growth and investment areas as mentioned by Dale Magaya. Not only are terms like Internet of Things (IoT) and Big Data on everybody’s lips these days, but localization and skills developments are just as important in order for Africa’s economy to elevate to the next level. These issues will form part interactive panel discussions among technical case studies during the event”, he concludes.

Denel remains positive about its future as the issues raised by Fitch Ratings will be resolved through

the successful implementation of the company’s recently approved strategy. Fitch Ratings recently down-graded the company’s national long-term rating from ‘AA-(zaf)’ to ‘B(zaf)’.

“We know that Government is cognisant of the fact that Denel is in need of additional liquidity to rebuild its business,” says recently appointed Denel Group Chief Executive Officer, Danie du Toit.

During the Minister of Finance budget speech in February, Minister Mboweni announced a contingency reserve of R13 billion for 2019/20 which Denel is preparing to submit a funding application.

Denel has undertaken a strategic review of its business to establish the extent and timing of the required government support, taking into account the benefits to be realized as implementation of the company’s strategic plan gains traction.

A lot of headway has been made by the current Board in support of the turnaround and growth of the business.

“The Board has taken far-reaching steps to

restore good corporate governance. We have a new experienced management team, with a number of executive positions currently being filled as we speak. We have a new strategy and a management structure that has recently been approved to stabilise Denel and achieve long-term growth”, says Du Toit.

As part of the company’s new strategy, Denel will dispose of non-core assets, including under-utilized properties and enter into strategic equity partnerships in some of its businesses to strengthen market access and enable the development of new technology, whilst ensuring the protection and growth of strategic defence capabilities.

Part of the turnaround has seen the company put systems and processes in place to strengthen governance, improve

BUILDING SUSTAINABILITY THROUGH LOCAL MANUFACTURINGThere is enormous potential for southern African manufacturers to increase market share both locally and internationally. The driving force behind capturing this growth opportunity is the South African Capital Equipment Export Council (SACEEC).

According to Eric Bruggeman, CEO at SACEEC, part of the Council’s mandate is to organise outward selling and inward buying missions. “We identified a need to showcase the offerings of the SADC region’s local manufacturers in an

interactive manner. The result is the inaugural Local Southern African Manufacturing Expo (LME) being held at the Expo Centre, Nasrec from 21 to 23 May 2019.”

“Endorsed by the Premier of Gauteng, David Makhura, we believe that the exhibition will enable exhibitors to meet with top decision makers from the inward buying missions already committed to the event. As Industry 4.0 continues to transform the way that manufacturers do business, LME 2019 will provide them with an opportunity to grow their customer base, with the knock-on potential for fostering job creation,” says Charlene Hefer, portfolio director for Specialised Exhibitions Montgomery.

“It is critical for the sustainability of local manufacturing operations that they aggressively pursue opportunities to increase their market share. Not only is this relevant to their increased permeation of the overseas market, but furthermore, they need to capture market share that is currently being monopolized by importers. Recent statistics indicate that South Africa currently imports products to the value of a staggering $83.2-billion. If we were able to shift this demand to the local manufacturing sector, we could realistically create 1.329-million jobs,” says Bruggeman.

LME 2019 will give local manufacturers from South Africa and other SADC regions a chance to not only display their capabilities and capacities to a captive audience, but furthermore it creates a forum for the exhibitors to network with their peers.

“We are excited about the prospect that local manufacturing operations have to evolve and expand by interacting with the inward buying mission representatives. Added to this are the benefits derived by the support of SACEEC, together with AREI (Association of Representatives for the Electronics Industry) and the dti (Department of Trade & Industry). We urge local manufacturing companies throughout southern Africa to capitalise on the unique marketing opportunities of exhibiting at LME 2019,” says Hefer.

“We are confident that the outlook for Denel will be further improved once the implementation of the new strategy and operational plan are in place and all corporate governance issues have been successfully dealt with,” says Du Toit.

Denel has established a team to investigate all cases of possible irregular expenditure and recommend corrective action. “There will be consequences for those executives implicated in irregularities including disciplinary and legal action taken against the individuals” says Du Toit. The company is also cooperating with the judicial commission into state capture – Zondo Commission of Inquiry – and investigations by the Special Investigating Unit (SIU) and other applicable state agencies.

Key issues identified by the Auditor General in the last assessment of Denel’s financial statements are being addressed. An indepen-dent audit firm was appointed to bridge the IFRS technical skills gap within the organizations and Denel’s supply chain management policies are currently being reviewed.

Cutting Tool Talk

THE RIGHT GRADE CREATES THE RIGHT TOOL – SELECTING TOOL MATERIALSCutting tools have different design configurations. Some of them are assembled comprising a body with replaceable cutting elements (indexable inserts, for example), another is wholly produced from solid material. Functionally, a cutting tool may be divided into a cutting part that is involved in cutting and a mounting part, which is necessary for mounting the tool in a holder or a machine spindle.

A tool material is the material from which the cutting part of a tool is produced. This is the material that

directly contacts a workpiece during cutting.

The tool material must be harder than the workpiece material so that it can cut the workpiece. In machining, the tool material needs to withstand mechanical and thermal loads and oxidation. These factors cause gradual loss of the tool material or a change in its original shape: this is known as tool wear. When wear reaches a certain limit, the cutting part cannot work and the tool fails. The machining time interval, within which the tool cuts normally from its original (new) state to a failure, is known as tool life. The tool must meet appropriate requirements of hardness, strength and thermal and oxidation resistance to withstand wear and ensure an acceptable tool life.

Cutting tool manufacturers produce a variety of tools from different tool materials according to the desired tool application. “Which material is more suitable for my specific needs? Is the material of one producer better than another?” Customers often ask themselves these questions when selecting the tool or choosing their cutting tool supplier.

Industry utilizes the following tool material groups to produce cutting tools: high speed steel (HSS), cemented carbide (hard metal, HM), ceramics, cermet and ultra-hard materials such as cubic boron nitride (CBN) and polycrystalline diamond (PCD). Each group features various types within the group; these are referred to as tool material grades or simply grades.

Classification

International standard ISO 513 classifies tool material based on their reasonable applicability with respect to the materials. ISCAR adopted this standard and uses the same approach in tool development. In accordance with the standard, the tool material grades are characterized by a class of engineering materials, to which a tool produced from the grade can be applied successfully. Each class has a specific identification letter and color:

P (blue) – steel and cast steel except stainless steel with austenitic structure

M (yellow) – austenitic and duplex (austenitic/ferritic) stainless steel and cast steel

K (red) – cast iron

N (green) – aluminum and other non-ferrous metals and materials

S (brown) – high-temperature superalloys and titanium

H (grey) – hard materials like hardened steel and cast iron, chilled cast iron

A classification number follows the letter to show the hardness-toughness ratio of the

grade according to a conventional scale. Higher numbers indicate an increase in grade toughness, while lower numbers indicate an increase in grade hardness. Higher numbers represent increasing feed and lower numbers represent increasing speed.

Cemented carbide

Cemented carbides are very hard materials and therefore they can cut most engineering materials, which are softer. Some carbide grades demonstrate better performance than others when applied to machining a specific class of materials.

A carbide grade is the result of combining cemented carbide, coating and post-coating treatment. Only one of these components – the carbide – is an essential component of the grade. The integration of coating and post-coating elements depends on the main field of the grade application. Produced by powder metallurgy technology, cemented carbide is itself a composite material and comprises hard carbide particles cemented by a binding metal, which is principally cobalt. The term cemented carbide can refer both to the substrate of a coated grade and to an uncoated grade.

Main types of cemented carbide include tungsten (wolfram) carbide (WC), tungsten carbide and titanium carbide (TiC) and tungsten carbide, titanium carbide and tantalum carbide (TaC). Mixed binders, containing not only cobalt but additional elements such as ruthenium, may significantly improve grade performance.

Most cemented carbides used for producing cutting tools integrate wear-resistant coating and are known as coated cemented carbides. Applying a thin-layer coating to a cemented carbide considerably improves the carbide’s working characteristics. The coating may be one- or multi-layer depending on the number of coating materials. Materials used for coating cemented carbides include tungsten carbide and titanium carbide (TiC), alumina (aluminum oxide Al2O3), titanium carbo-nitride (TiCN), and titanium aluminum nitride (TiAlN). There are also various post-coating treatment processes that are applied to already coated cemented carbide, for example, to the rake surface of an indexable insert.


Coating Processes

Two methods may be utilized for coating: Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). CVD coating is based on chemical reactions in a vaporized medium and PVD uses material sputtering. Technology development allows both methods – CVD and PVD – to be combined for coating cemented carbides as a means of controlling coating properties. For example, ISCAR’s carbide grade DT7150 features a tough substrate and a dual MT CVD (Medium Temperature CVD) and TiAlN PVD coating. The grade was originally developed to improve machining special-purpose hard cast iron.

Nano layered PVD coating

PVD coatings were introduced during the late 1980’s. Applying advanced nanotechnology, PVD coatings performed a gigantic step in overcoming complex problems that were impeding progress in the field.

Developments in science and technology brought a new class of wear-resistant nano layered coatings. These coatings are a combination of layers having a thickness of up to 50nm (nanometers) and demonstrate significant increases in the strength of the coating compared to conventional methods.

Applying SUMO TEC technology

SUMO TEC is a specific post-coating treatment process developed by ISCAR to improve both CVD and PVD coatings: CVD and PVD. In CVD coatings, the difference in thermal expansion coefficients between the substrate and the coating layers causes internal tensile stresses and micro cracks. PVD coatings produce surface droplets. These factors negatively affect the coating and shorten insert tool life. The SUMO TEC treatment has the effect of making coated surfaces even and uniform by reducing and even removing the defects – minimizing inner stresses and droplets in the coating.

Classifying Grades

ISCAR, which produces a variety of cutting tools with cutting parts mainly fabricated from coated and uncoated cemented carbide, developed a tool material grade characterization system with designated letters indicating the material group and numbers representing as identity codes. The numbers also provide quick information on the grade type – for example a two-digit number following “IC” in the designation of a cemented carbide grade means that it is an uncoated grade, while a three-digit number relates to a coated grade.

Occasionally, misconceptions occur concerning grade designation for a coating

EXPANSION OF SUMOCHAM DRILL RANGE

ISCAR is expanding the small diameter range of its leading SUMOCHAM hole making line to include new heads and

tools from 5.0mm up to 5.9mm.

The all-new SUMOCHAM heads are available in 5.0 up to 5.9mm diameters, with 0.1mm increments. The 5.0 to 5.9mm drilling range is covered by two SUMOCHAM DCN drill body sizes, available in 3xD and 5xD length to diameter ratios.

Made from IC908 TiAlN PVD nano layer coated grade, the ICP drilling head features high wear resistance with stable and predictable wear progression and a possible IT10 tolerance.

The DCN drill is fitted with a high strength steel body and internal coolant supply, with the end specifically designed for efficient MQL (minimum quantity lubrication) coolant operation. Its small-diameter shank is suitable for collet adaptation and Swiss-type machines.

The inserts are supplied in custom designed SK DCN clamping keys, whose user-friendly and ergonomic design enables easy insert mounting with no setup time.

type. IC300, for example, relates to the specific grade in its entirety – including both the grade substrate and coating. Wording such as grade IC328 but with coating IC300 is inaccurate; the correct definition would be substrate as in grade IC328 and coating as in grade IC300.

The best grade is a grade you have now

When a new insert (solid carbide tool or replaceable cutting head) is developed, it is necessary to decide from which grade it will be produced. The answer to this question depends on the insert’s designated application and this represents a starting point for tool designers in their work. Grade properties and their relative hardness-toughness ratio will be the main determinants to take into consideration. In some cases, stock availability and delivery terms may be the significant factors in the decision-making process.

As people engaged in production like to say, the best carbide grade is the grade that you have in your stock. This statement can be applied to the cutting tool as a whole; it is probably true if it relates to a production

situation that requires an immediate decision. However, productive process planning – or effective tool stock management – requires a more in-depth applicative analysis of the pros and cons of the proposed carbide grades.

Selecting a grade is strongly connected with the cutting geometry of a tool and other factors. The cutting tool manufacturer should provide the customer appropriate information about grade properties to assist in their correct selection. While computerized grade selection systems are impressive and effective, often simple graphical figures, charts and tables can act as a good information compass to visualize a grade position in the field of application in accordance with standard ISO 513 and characterizing the grade properties compared with other grades.

ISCAR uses charts and tables to specify the cutting area of milling tools (Fig 1 & 2) and proposes suitable grades for replaceable inserts in indexable milling cutters, solid (mainly solid carbide) endmills and replaceable solid milling heads with Multi-Master adaptation.

ISCAR characterizes the grades as main and complementary. The main grades are more popular in machining specific engineering materials, but complementary grades can be effective as well in certain cases. When a main grade is not available for producing a certain product, a complementary grade provides an acceptable alternative.

The tables provide summary data for grade applications and the charts show an applicative map of grades, in coordinates of classification numbers from standard ISO 513. The figures often prioritize the main grades by numbers in brackets below the designation of a grade. Prioritizing is general in character and is intended to assist in selecting the correct grade when there is insufficient information about the application.

The basic principle for selecting the grades is that when abrasive wear is dominant, a hard grade should be used, whereas a tough grade is needed for substantial mechanical loading during cutting. For example, for finish milling with typically small machining allowance (machining stock), high cutting speed and low feed, hard grades will be more efficient. However, tough grades will be required for heavy-duty roughing that removes significant volume of material and features considerable cutting load.

Using summarized tables and charts to represent performance attributes of various parameters is a well-known grade selection tool that is often preferred by tool manufacturers, even with the myriad of digital options available today. The simplicity and clear visuals offered by the traditional tables and charts provide important data in an easily interpretable and effective way, allowing optimal selection of the right tool materials for each application.

INTERACTIVE CONTROL TO GUIDE INDUSTRIAL ROBOTS

Scientists at the Fraunhofer Institute for Machine Tools and Forming Technology IWU have developed an

innovative technology enabling people and large industrial robots to work together in an intuitive way that feels a lot like human teamwork. Using the benefit of this technology, robots can recognize gestures, faces and postures to make this collaboration that much safer and more efficient. Fraunhofer IWU presented this innovation at the Hannover Messe Preview in January, 2019 as well as presenting it at Hannover Messe in April 2019.

A cursory glance at shop floors is all it takes to see human-robot collaboration has gone mainstream in manufacturing. However, a second glance reveals that this is more to each his own than we’re in this together. Heavy-duty robots operate alongside their human coworkers without safety fencing, but direct interaction is a no-go. Safety precautions dictate that the robot freezes as soon as a human sets foot in a sizable surrounding safety zone.

Safe, effective and direct – a better way of working together

The Fraunhofer Institute for Machine Tools and Forming Technology IWU has come up with an unprecedented technology to make human-machine teamwork more efficient, benefiting the entire manufacturing workflow.

“We have added effective, secure and flexible interaction to legacy technology. This is the first time humans can communicate and collaborate directly with heavy-duty robots based on hand gesture in the industry,” says Dr.-Ing. Mohamad Bdiwi, head of department for robotics at Fraunhofer IWU. This collaboration goes something like this on the shop floor: The machine recognizes human gestures, faces and postures when a person enters the robot’s work zone. This data serves to make the teamwork safe and to control the robot. The human simply gestures, using hands and arms to instruct the mechanized coworker to perform a task. The robot is able to interpret even complex movements. “Our technology brings gesture control to industrial applications. To date, it has been used mainly in gaming applications,

for example, consoles,” adds Bdiwi. The robot does not only track hands, it also scans faces. For example, if the human glances sideways or rearward to talk to another coworker, the machine knows to ignore gestures meant for others. Human and robot can work together directly and even pass parts and tools back and forth. The robot sees when a hand is too close to the worker’s face and waits for it to be extended out of the danger zone before handing the object over. This human-robot interaction comes courtesy of smart algorithms and 3D cameras that lend the robot the power of sight.

The algorithms are ready for action. Visitors to Hannover Messe can see a gesture-controlled, interactive demo application at Hannover Messe in April, 2019.
