1.5 Necessary preparatory measures

Actions to be undertaken by the customer

The customer is responsible for the following preparatory measures:

Installation site

• Prepare the installation site of the machine

- see "Installation site"

• Ensuring the availability of:

- Supply of electricity, light, water, telephone

Transport

• Arrangement of unloading of the machine

• In-house transport to the installation site and installation of the machine

- The machine is to be transported to the installation site

- The machine is to be placed onto the levelling elements

E/P connection

• Connection of the machine

- Machine must be connected electrically ("CW rotating field").

- The machine must not be connected to a power supply with a residual-current circuit breaker. (Permanent connection necessary)

- Upon delivery to countries with large voltage fluctuations in the supply line of the system, a power supply stabilizer must be used in order to protect the electronic components.

- The machine must be connected to the compressed air supply

Commissioning

• Preparation for commissioning

- Preparation of the necessary lubricating oils / coolant lubricants

- Clean machine (degreasing)

- The temperature at the installation site must be controlled to a constant value.

- Align machine: +/- 0.1 mm/m

- Provide suitable assistants during commissioning

Planning documentation

1.6 Installation site

Customer information

It is imperative that this information is checked, safeguarded and implemented by the customer prior to the delivery of the machine.

The customer remains responsible for the correct location of the machine. The customer is fully responsible for an appropriate installation site.

If problems should occur later on that have been caused by a non-observance of the notes, DMG ECOLINE cannot be held responsible.

Ambient temperature

A fully air conditioned room fulfils all of these conditions.

• Constant room temperature of +/- 1°C. (Not a certain value, like e.g. 20 °C)

• It is very important that the temperature is the same in all machine points.

Wear reduction

In order to reduce the wear, there must be no machines in the same room which produce dusty machining residues:

Figure 1-6

• Also prevent grinding or erosion dust from entering the machine via workpieces and coolant lubricant.

ATTENTION!

DMU50ECOLINE-pu-enPage 1-6

Planning documentation

Corrosion prevention

In order to prevent corrosion at workpiece and machine, the installation site must be dry and free of aggressive vapours:

Figure 1-7

• No soldering, welding, varnishing, pickling or electroplating systems in the same room.

Foundation

An appropriate bottom plate that has been approved by the structural analyst (engineer engaged in statical calculation) is necessary.

Figure 1-8

• The bottom plate must not have any expansion joints in the area covered by the machine.

• Cracks, cable ducts or other interruptions are not allowed in the area covered by the machine.

• Place the machine onto a firm ground that makes sure that the machine is stable

• The machine must constantly be levelled in order to guarantee the accuracy of the machine.

• The floor must not be elastic so that the machine stays aligned precisely.

• The installation area must be free of oil and grease so that the coefficient of friction of the installation elements is not reduced.

• The ground must be firm and resistant against all liquids used at the machine in accordance with the locally valid environmental regulations.

DMU50ECOLINE-pu-en Page 1-7

Planning documentation

Load bearing capacity

Ensure a sufficient load bearing capacity of the floor:

Figure 1-9

• Have the load bearing capacity checked by a structural analyst (engineer engaged in statical calculations).

Have the structural engineer determine in a binding manner

• that the floor, basement floor, intermediate floor or substructure has the required load bearing capacity (especially in old buildings),

• that the installation site is in conformity with applicable building regulations.

Centre of gravity

Please note that the centre of gravity is shifted due to the workpiece weight and to the traversing paths.

Maximum weight

For the floor load bearing capacity, take into account

Figure 1-10

• the maximum installation weight of the machine and additionally the maximum weight of tool and accessory cabinets including contents,

- workpieces and devices,

- people,

- transport means,

- other devices in the immediate vicinity of the machine.

kg

ATTENTION!

DMU50ECOLINE-pu-enPage 1-8

Planning documentation

Basement floors, intermediate floors

When installing the machine on basement floors, intermediate floors or on other load-bearing structures:

Figure 1-11

Ask a structural analyst experienced in structural dynamics (engineer engaged in statical calculations) to certify in writing according to DIN 4024 Part 1: flexible structures that support machines with rotating elements,

• that the supporting structure is capable of bearing the effects of the forces of gravity of the machine,

• or, if this certification cannot be provided, that the measures for vibration damping that are then to be arranged are adequate.

Floor vibrations

Figure 1-12

Floor vibrations or shocks caused by adjacent machines or other producers must not affect the function and accuracy of the machine.

For absorbing vibrations, it generally suffices to place the machine onto vibration insulating plates. If necessary, an isolated foundation must be provided.

Figure 1-13

DMU50ECOLINE-pu-en Page 1-9

Planning documentation

Access

Figure 1-14

Adequately large access openings must be available for moving the machine to its installation site.

Room height

Figure 1-15

Please note that the room is high enough to enable installation and maintenance work to be executed without impediments.

Machine area

Figure 1-16

Make sure that there are no columns or other obstructing objects in the machine area which could cause impediments when executing installation and maintenance work.

DMU50ECOLINE-pu-enPage 1-10

Planning documentation

1.7 Ambient conditions for the machineA fully air conditioned room fulfils all of these conditions.

• Constant room temperature of +/- 1°C.

(not a specific value, like e.g. 20 °C)

It is very important that the temperature is the same in all machine points.

• Permissible ambient temperature: +15° to + 35° C

• Maximum relative air humidity: 80 %

• Maximum installation altitude: 1000 m above sea level

If one of these values is exceeded at the installation site of the machine or in case of special operational conditions, e.g.

• action of powerful electric or magnetic fields

• installation in potentially explosive atmospheres or areas containing potentially explosive substances

contact your DMG ECOLINE (DMG) representative.

1.8 Note for machines with series transformersThe cable connection between the overcurrent protection device (main fuse) and the separate series transformer depends on the operating voltage at the customer. Appropriate protection against short circuits is to be provided by the customer.

The cable for the connection between the series transformer and the machine is part of our scope of delivery (in accordance with the installation site in the installation plan).

1.9 Empty conduits for external data transferIf external data transfer is planned, appropriate empty conduits made of metal must be installed for the data cable.

Data cables must not be laid alongside cables carrying high currents or cross such cables.

1.13 Electrical power supply

1.13.1 InstallationDuring the electrical installation, attention is to be paid to ensuring EN 60 204, part 1, point 6.3.3 "Protection by automatic interruption of the power supply" is met.

On this topic, also see IEC 364-4-41 (DIN 57 100, VDE 0100, part 410).

The machine must not be connected to a power supply with a residual-current circuit breaker. See EN 50 178, section 5.3.2.3.

As our machine has a leakage current higher than 3.5 mA AC due to EMC measures, it must have a fixed connection.

Furthermore, one of the measures specified below must be executed according to EN 50178, section 5.3.2.1.

• Cross section of the protective earth conductor at least 10 mm2 Cu (see "Electrical data").

• This also applies to special systems that may have been connected directly to the customer's power supply and that have not been routed across the machine.

or

• Monitoring of the protective earth conductor by a device that will automatically shut down the electronic equipment in the event of a fault.

or

• Laying of a second conductor, electrically in parallel with the protective earth conductor, using separate terminals. This conductor must fulfil the requirements for protective conductors on its own according to section 543 of the harmonization document (HD) 384.5.54 S1 (old DIN VDE 0100 part 540) for protective earth conductors.

If the supply voltage is a TN-S power supply and if the 400 VAC operating voltage is within the tolerances ± 10%, i.e. 360 VAC to 440 VAC, the machine may be connected directly.

If the supply voltage is a TN-S power supply and if the operating voltage is not within the limits of 360 VAC to 440 VAC, the machine requires a pre-disconnecting transformer.

1.13.2 Main fuseThe overcurrent protection (main fuse) for the mains connection cable must have been installed outside of the machine and is not part of the scope of delivery of DMG ECOLINE.

DMU50ECOLINE-pu-enPage 1-32

Planning documentation

1.13.3 Machine connection:The power supply for connecting the machine or parts of the machine must be a TN-S power supply with 3 conductors (L1, L2, L3) and a neutral conductor (N) as well as a protective earth conductor (PE).

Power supply. . . . . . . . 3 phases (L1, L2, L3), neutral conductor and protective conductor, 50/60 Hz, 400/230 VAC with tolerance ± 10%

The actual mains voltage is not allowed to vary from the rated voltage by more than the permitted tolerance, even under load.

Cross section of the connection cable according to DIN 57100 / VDE 0100 or other locally valid standards!

Risk of accident due to electrical voltage!

• The electrical connection is only allowed to be made by an electrician.

• Observe primarily the locally valid regulations and directives.

When working on electrical equipment, damages may occur at electronic components due to incorrect or faulty connections. Always observe the specifications in the wiring diagrams.

Supply cable, fuse protection

Power supply and fuse protection are to be designed as per the information on the type plate for the switch cabinet.

1.18 Application and maintenance of coolant lubricants

Increased danger of accidents when using oils and coolant lubricants! Protective goggles must be worn when working with oil or coolant lubricants.

General

Only the correct selection of suitable coolant lubricants as well as proper care and maintenance of the coolant lubricant will ensure that no problems arise.

In the following, some important aspects for the quality of manufacture and the ecology are listed:

• Mineral oil content

• Water polluting classes

• Additives

• Universal suitability for a wide range of machining tasks and materials

• Skin tolerance

These aspects are to be specified by the machine operator himself and lie within his scope of responsibility.

The selection of the coolant lubricants as well as their care is the task of the machine user. However, here the requirements placed by DMG ECOLINE GmbH must be met.

DANGER!

DMU50ECOLINE-pu-enPage 1-44

Planning documentation

For this reason, DMG ECOLINE GmbH cannot be held responsible for machine damage caused by the organisation operating the machine by

• the use of unsuitable coolant lubricants

• the lack of, or incorrect care and servicing of the coolant lubricant

• the use of unsuitable mixing water.

In case problems arise, please consult the supplier of your coolant lubricant (CL supplier). We would be pleased to provide assistance if you have any further questions.

Deliberately, specific products are not recommended; only information on chemical-physical and microbiological guidelines and properties is stated.

The coolant lubricant must be matched to the mixing water for the coolant lubricant emulsion and the machining tasks without fail.

In case of a written confirmation by your coolant lubricant supplier, that the coolant lubricant delivered by him fulfils the parameters (see "Requirements and specifications for the coolant lubricant used in the machine"), nothing speaks against its use in machines made by DMG ECOLINE.

In order to ensure a safe functioning of the machine/system, the water-soluble coolant lubricant must be inspected at least once per week (also in case of a machine standstill) as far as the concentration, the pH value, the bacteria and the attack by fungi are concerned (see "Requirements for the inspection and documentation of the coolant lubricant").

The proof for the adherence to the given limit values is given by tests listed in the guideline which are normally executed by your coolant lubricant supplier or by independent laboratories, if you do not have the necessary equipment yourself.

ATTENTION!

Planning documentation

Explanations

About 1.) The inspection for corrosion protective measures is executed with the grey cast iron chip test in accordance with DIN 51360 part 2. The DIN method foresees a reading after one hour. However, at variance with this requirement, the filter papers are assessed after 1 hour and after 12 and 24 hours. The assessment scale is in accordance with DIN 51360 part 2.

About 2.) The coolant lubricant should not degrade the properties of the coating in the cross-hatch test in accordance with DIN EN ISO 2409 after soaking for 14 days at 50 °C. Also, the paint hardness in accordance with (EN ISO 2815) should not be degraded. In the round bar bending test (12 mm) on a coated 0.7 mm metal plate there should not be any cracking up to 45°.

About 3.) In accordance with DIN 53505, the values for Shore hardness A and D must remain unchanged, also the linear dimensions in accordance with DIN 53534.

About 4.) On machine tools with a dedicated coolant lubricant system, analyses, care and the addition of service chemicals are often uneconomical, for this reason the coolant lubricants must have suitable basic properties and stability for this type of machine from the start. A suitable coolant lubricant should demonstrate the necessary bio stability reserves in the inoculation cycle test.

DMU50ECOLINE-pu-enPage 1-48

Planning documentation

Abbreviated test description for inoculation cycle test:

Solutions or emulsions are prepared from the coolant lubricants to be tested using sterile standard water (20°dH). The mixtures are inoculated with reference germs once a week. By means of subsequent, weekly determination of the pH value, the corrosion protection properties (filter paper chip test) as well as the determination of the number of colonies, the limit for the micro bacterial load is determined. The following germs are used for this purpose:

Mixtures of bacteria:

• Pseudomonas aeroginosa (NCIB 6749)

• Shewanella putrifaciens (NCIB 12202)

• Citrobacter freundii (NCIB 12203)

• Alcaligenes faecali (NCIB 13104)

Mixtures of fungi:

• Fusarium solani

• Geotrichum candidum

About 5.) Qualitative evaluation of the non-ferrous metal corrosion with copper strips made of electrolytic copper.

DMU50ECOLINE-pu-en Page 1-49

Planning documentation

About 6.) During this test, 25 ml of the 5 % (percentage by weight) CL mixture is evaporated in a glass Petri dish with the water from the user. The bonding behaviour is stated as "honey-like" (draws thin threads), "thick" (paint-like film), "transparent adhesive tape" (bonds like transparent adhesive tape, contact surface similar to familiar adhesive tape). The bonding action should be as weak as possible. Please note that an excessively strong bonding action can have negative effects on the machine functions, particularly if the machine is not used for an extended period of time.

About 7.) The test is suitable for comparing the tendency to form foam and foam stability of coolant lubricants. In an extension, it is also possible to determine the "soda effect" (tendency to discharge due to bursting foam bubbles). Coolant lubricants and CL working solutions with inadequate foam properties can be detected more easily.

For this reason, the following general requirements apply to the coolant lubricant:

• They must be non-polluting and suitable for the workplace. Consequently they must be free of nitrites, PCB, chlorines and nitrosable diethanolamine (DEA) (as per TRGS 611).

• It should be possible to provide skin tolerance assessments.

• Mineral oil content in accordance with DIN 51417 at least. 40 % in the concentrate.

• As far as possible, they must be suitable for universal application for all machining tasks and materials.

• High cutting performance due to appropriate additives.

The coolant lubricant is not allowed to contain more than 15 % by volume of inflammable liquid (e.g. oil). Deflagration / danger of explosions!

When using coolant lubricants with an increased portion of combustible fluid, an additional "explosion protective package" machine is under all circumstances necessary (inquiry at DMG ECOLINE).

DMG ECOLINE does not assume any guarantee for follow-up damages, if inappropriate coolant lubricants are used!

1.20 Requirement for the technical specification of the mixing water:(Please also follow any applicable regulations and limits from your regional water authority)

Explanation

About 1.) The optimum total hardness for mixing coolant lubricants is generally 8 - 12 °dH (1.4 - 2.1 mMol) and it is recommended to keep to this range. Please clarify the optimum water conditions with your CL supplier and take actions as necessary. Have the limits confirmed in writing by the CL supplier.

About 2.) In case of deviations, it is imperative you discuss possible methods of water treatment with your CL supplier and implement the necessary measures.

About 3.) If the conductivity of the mixing water is higher, there is an increased risk of corrosion. It is imperative to treat the water appropriately.

About 4.) In case of a high chloride content, there is an acute risk of corrosion, for this reason it is imperative to treat the water appropriately.

About 5.) It is imperative the mixing water is germ-free (drinking water quality), as otherwise there is an increased risk of micro bacterial infestation and corrosion. Problems are often caused by poorly maintained water treatment systems. Please contact your coolant lubricant supplier under all circumstances.

No. Parameters: Limit values: Unit:

1 Total hardness 5 - 20 recommended 8 - 12 (0.9 - 3.6)

°dH (degree of German

hardness), (mMol)

2 pH value 7 +/- 0.5 pH

Mixing

Please note the anticorrosion data in the VKIS data sheet (manufacturer's specifications) in order to reach the recommended concentration for the necessary anticorrosion effect.

A mixer must be used to prepare the emulsion.

Only add fully mixed emulsion to the coolant lubricant system!

• Do not use clear water, since this will cause corrosion immediately

• Ideal water hardness: 8 - 12 ° dH

In case of deviations from this standard value, malfunctions of the coolant lubricant system (saponification of the coolant lubricant at the edge-type filter due to a too hard mixing water) or to a bubbling over of the coolant lubricant in case of a too soft mixing water!

Do not store emulsion in zinc-plated containers.

Mixing temperature: When mixing the emulsion, please note the following mixing temperatures, as excessively large temperature differences between the concentrate and mixing water can cause complications.

Minimum Maximum

Concentrate 20° C 30° C

Mixing water 20° C 30° C

ATTENTION!

1.21 Coolant lubricants not soluble in water

Coolant lubricants (cutting oils etc.) with an oil content of >15 % may only be used in connection with a machine which has been equipped with an "explosion protection package"!

It is not admissible to use non-water-soluble coolant lubricants (cutting oils) due to safety reasons (danger of explosion).

High machining performance and the related higher tool speeds will result in heavy atomisation of the coolant lubricant that cannot be mixed with water.

There is the possibility of a deflagration or of an explosion.

Hazard due to deflagration

Deflagrations at the machine or in the machining environment may occur if the following conditions occur at the same time:

• In case of cutting operation including the grinding of metals at the machine.

• On the use of a coolant lubricant with more than 15 % by volume oils or concentrates (with flash point) or less than 85 % by volume water content.

• When splashing or atomizing coolant lubricants to a large extent with a concentration exceeding 10 g/m3

• The machine has a limited or enclosed chamber (machine housing, machine encapsulation) where an explosive mixture can build up.

Measures

When using non-water-soluble coolant lubricants, an additional "explosive protection package" is under all circumstances necessary. (Inquiry at DMG ECOLINE).
