THE EXPERT’S VIEW

LUIS URIARTE

On the right path…THE EXPERT’S VIEW: by Luis Uriarte, IK4-TEKNIKER Market Manager


A blend of ideas, creativity and knowledge connected to diff erent technologies. These are the ingredients that IK4-TEKNIKER needed to produce signifi cant changes in the way companies design and manufacture their pro-ducts. This requires a high degree of specialisation in our technologies, an understanding of market needs as well as a close cooperation with our customers because they are the specialists in their own fi elds.

I would like to underscore a few of their most relevant watershed landmarks.

For instance, I remember the time when the fi rst-ever high-speed linear drive motors were made in our coun-try. They were named BIZKOR and won the 1998 national design award.

During the design and construction stage we travelled to Germany on several occasions to visit reference centres such as ZTF in Stuttgart to learn more about linear mo-tors recently launched in the market. That was a turning point, not so much because of the award itself, but rather because we managed to dispel any reluctance present in the machine tool sector with regard to using linear mo-tors as a suitable constructive solution for highly dyna-mic machines.

Focusing now on the smallest scale of manufacturing, i.e., the micro and nanoscale, it can also be stated that our fi rst major industrial project related to applying micro-manufacturing capabilities was another outstanding landmark.

In 1997, IK4-TEKNIKER implemented a Specialisation Plan that included setting-up an R&D unit for ultrapre-cision technologies. In 2001, the plan gave rise to a new micro-manufacturing laboratory called “Tekniker Micro Machining” (TMM).

By the year 2005 we were already producing the fi rst range of dental brackets using microinjected high perfor-mance materials. To achieve this goal, a process had to be implemented that consisted in resizing polymer brackets and manufacturing single units directly by micro-milling in order to pass functional tests and obtain health accre-ditations to eventually manufacture micro moulds to be used at a later stage. This was done in close cooperation with EuroOrtodoncia under patent PCT/ES2005000346.

Since then, our micro-manufacturing laboratory has de-veloped several ranges of increasingly complex brackets.

Our specialisation in the design and construction of uni-que, ultra- high precision equipment has allowed us to work with reference centres such as the Spanish Metro-logy Centre, Spain’s primary laboratory.

I also remember, thinking now about other pieces of complex equipment, the construction and implementa-tion of the current national pressure standard reference pattern. Although it was introduced in 2009 it can still be rated as the world’s most accurate barometer capable of discerning atmospheric pressure diff erences between the upper and lower segment of the palm of a hand.

These and other landmarks have allowed us to provide the industry with the know-how generated by our re-search activities at diff erent points in time.

It is frequently diffi cult to put your stakes on one techno-logy or another because the market does still not exist. As a technology centre, we must anticipate the future needs of our industry and its fi rms. Whenever we address many of the projects mentioned here, not only are we aware of the path we’re following but also know their signifi cance as landmarks when we imagine what our lives would be like without them.

Increasingly more sophisticated Industrial

lubricantsDr. Luis Fernández Ruiz-MorónProject Manager at the Repsol R&D Centre

Dr. Luis Fernández Ruiz-Morón is a project manager at Repsol’s R&D Centre and is also responsible for the tribology section. He recently attended the LUBMAT 2016 conference as a keyspeaker. During this interview, Fernández Ruiz-Morón explains how important it is to manage lubrication properly.

REPSOL’S R&D CENTRE

Environmental regulations are being tightened up, more advanced formulations are being developed and the industrial sector is exploring new pathways to become more effi cient and competitive. These are some of the reasons that are transforming the lubricant market. What is this revolution actually all about?

Generally speaking, lubricants and the oil & gas sector are undergoing signifi -cant changes because due to the above mentioned factors. As the environment in which we operate is technically com-plex, it is becoming increasingly nece-ssary to network via consortiums and multi-disciplinary teams. End users are demanding better performance: more protection for their machines and less oil changes. Environmental restrictions, on the other hand, are increasing and this limits the number of substances used in the formulation of lubricants. It means that equipment manufacturers are for-ced to make changes in their designs to reduce emissions carrying CO2, particles and other contaminants: new materials, processes, after-treatments, etc., that infl uence lubricant composition. Lastly, more and more people are asking for a simplifi cation of specifi cations issued by manufacturers and international bodies such as ACEA or API.


Tribology is playing a key role in the development of increasingly advanced lubricants, but how exactly?

Every tenth of a second matters in the struggle to reduce CO2 emissions. Advances made in lubrication systems are proving to be the most cost-eff ective way of doing things. But not only that: Ma-chines and motors that are more effi cient, ecological and advanced require more complex lubricants: they must be compatible with biofuels and their negative eff ects in terms of friction control, and must adapt to downsizing and increases in thermal stresses. They must feature friction modifi er systems for protection against wear in the so-called ultra-light grades and must be capable of dealing with systems such as start-stop that multiply events beyond the range of hydrodynamic lubrication, just to mention a few examples. Mention must also be made of the progress made in terms of surface coatings and which has made it necessary to readdress lubricant formulations.

How would a company benefi t nowadays from decidedly putting its stakes on incorporating lubrication management to its value chain?

For many years, users have rated lubricants as a “pro-cess constant” with which you had to coexist and adapt to. Nowadays, we have over 1,000 lubricant references adapted to diff erent applications. Many of these lubri-cants have been exclusively developed for specifi c custo-mers who have managed to increase production, improve effi ciency or reduce maintenance costs by incorporating

lubricants with suitable bases and additives via an in-service oil moni-

toring system.

Some of the most outstanding European experts attended the LUBMAT

conference held in Bilbao on June 7. What would you underscore about this edition of the conference?

As this is my hometown, I feel extremely proud to say that this international conference hosted by UCLA and IK4-TEKNIKER has not only become an outstanding event over the years but also a must for professionals working in the fi eld of lubrication and maintenance, equipment manufacturers, scientists, tribologists, chemical engi-neers, physicists... Not only because of the quality and novelty of the presentations, but also because of the oppor- tunity off ered in terms of networking in a privileged se-tting like Bilbao (in this edition).

You were one of the keynote speakers. Could you briefl y summarise some of the issues you discussed in your presentation?

As I’ve already spoken about the environment and the situation we are currently dealing with, I would now like to say something about how these environmental, economic, political and technical changes have aff ected lubricant formulations. In particular, we have reviewed the use of synthetic bases, new friction modifi ers and activation systems. We have also addressed the comple-xity of the current specifi cations (the new ACEA 2016), the phenomenon of LSPI (Low Speed Pre-Ignition), fuel economy property testing and performance durability.

of BIEMH 2016 by

IK4-TEKNIKER

The technology centre can only draw very

positive conclusions with regard to the

event. It must also be underscored that,

compared to previous editions, visitorship

has increased.

IK4-TEKNIKER has reviewed BIEMH 2016 and can only draw some very positive conclusions such as a larger number of visitors compared to previous editions, new spaces dealing with issues specifi cally related to the sector itself and many interesting enquiries received.

That is how IK4-TEKNIKER participated in BIEMH 2016.

LASER METAL DEPOSITION TECHNOLOGIES TO MANUFACTURE AND REPAIR COMPONENTS

Additive manufacturing is an advanced manufacturing technique that allows structures and parts to be made by successively depositing layers of material.

One of the most widespread additive technologies of recent years is called La-ser Metal Deposition (LMD) in which a laser melts a metal powder that is in-jected on to the surface of a substrate to generate 3D structures and coatings.

This technique has numerous applications to address surface wear and co-rrosion resistance or perform repairs on components used in the automotive business, moulds, aeronautics or railways. It has also been used lately to ma-nufacture 3D structures and parts.

The Basque Technology Centre, IK4-TEKNIKER, has applied LMD to the rein-forcement of components and repairs involving tools, moulds and dies that have previously failed in machining operations or have undergone design modifi cations and develop defects during their operating life. Researchers have also addressed the production of metal parts and components used in complex structures, prototypes and on elements of a more functional character.

IK4-TEKNIKER has also made high quality stainless steel alloy structures with deposition rates close to 2 Kg/h.

It is within this fi eld of specialisation that experts at the technology centre have also used other kinds of materials such as tool steel grades for cold and

Additive manufacturingfor very large and complex parts

hot operations, nickel, titanium and cobalt-based alloys or tungsten carbide composites embedded in cobalt matrices on a number of metal bases.

Profi tability in large sizes

The LMD process is specifi cally geared towards the production of medium and large metal parts that in the past were produced by using conventional processes such as subtractive or forming techniques.

This new technology allows raw material consump-tion to be drastically reduced as the ratio between the amount of starting material required and what is ac-tually deposited is close to 1:1.

Both the savings obtained and shorter process times have made it possible to signifi cantly cut back the fi nal cost of manufacturing processes.

The LMD process is profi table in those sectors in which more than 80% of the workpiece is machined and when

the materials used on it can be barely be machined or are hard or abrasive. These are features commonly found in sectors related to energy, aeronautics and prototypes.

In addition to a short ‘lead time’, LMD responds quicker compared to sectors involving castings or injected parts. The absence of moulds also reduces lead time by more than 50% whenever single parts are involved.

The end results of the research work carried out by IK4-TEKNIKER in the fi eld of additive manufacturing were presented at the last edition of the Spanish Machine Tool Biennial (BIEMH) that was held from May 30 to June 4 at the Bilbao Exhibition Centre.

Additive manufactu-ring techniques will play a very active role in the fi eld of industry 4.0 as they will allow for the customisation of products and processes.

Industry 4.0, or the so-called fourth industrial revolution, is a new manufacturing paradigm based on integrating electronic, information and communication technologies within the scope of productive technologies.


The revision carried out in 2010 by ISO (the In-ternational Organization for Standardization) of the ISO 10360 technical standard introdu-ced the possibility of using laser interferome-try as a valid standard reference pattern for the calibration of coordinate measuring machines

(CMM) used to measure linear dimensions.

It is within this context that IK4-TEKNIKER is cu-rrently involved in a process aimed at obtaining a

certifi cate awarded by the National Accreditation Body (ENAC) for the calibration of medium-large CMMs (with axial lengths ranging between 1,500 and 13,500 mm) using tracer lasers to meet current market requirements with regard to fi nding more

accurate mechanisms in the entire calibration pro-cess with shorter machine downtime.

A signifi cant demandIn Spain there is a signifi cant number of CMM’s larger than 1,500 mm that are currently calibrated with stan-dard physical reference patterns. The main problem is

related to the complexity of using very long standard physical reference patterns quickly and reliably when a machine is to be calibrated.

IK4-TEKNIKER uses an ETALON AG laser interferometry system called tracer laser that follows a refl ector located near the machine’s feeler and also measures linear displa-cements. This is connected to two major advantages in terms

of the processes used nowadays:

On the one hand, precision is maintained at an interferometric level throughout the entire calibration process. On the other,

machine downtime is signifi cantly reduced, regardless of the size of the CMM. This measuring process was presented at the last edition of the Machine Biennial.

The ETALON AG - IK4-TEKNIKER partnership

ETALON AG is a crucial partner in this new service developed by IK4-TEKNIKER as this company is a benchmark in the metrology

sector that supplies innovative technology for geometric verifi -cation and the monitoring and upgrading of precision of machine tools, coordinate measuring machines and robots.

IK4-TEKNIKER is currently collaborating with ETALON AG as its offi -cial distributor in the Spanish market meaning. This means, on the one hand, that cutting-edge and precise know-how related to geome-tric verifi cation is readily available and, on the other, that a solid colla-boration is underway thanks to the agency agreement signed with this

leading industrial metrology fi rm.
