When using non water-mixable cooling lubricants (oil content > 15%) with flashing point ignita-
ble aerosol air mixtures might develop. There is a potential danger of explosion.
ATTENTION!
Only the correct selection of an appropriate combination of cooling lubricants and
slideway oils as well as the proper care and maintenance of the cooling lubricant can
ensure that no problems such as stick-slip effects or deposits are resulting.
The selection of cooling lubricants and slideway oils, lubricating oils or greases as well as their
care are being determined by the machine operator or operating company.
Therefore, Optimum Maschinen Germany GmbH cannot be held liable for machine damages
which are caused by unsuitable coolants and lubricants as well as by inadequate maintenance
and servicing of the coolant. In case of problems with the cooling lubricant and the slideway oil
or grease, please contact your supplier for mineral oils.
ATTENTION!
For safe functioning of the CNC-machine the cooling lubricant needs to be checked at
least weekly also during down times with regard to its concentration, ph-value,bacteria
and fungal decay.
ATTENTION!
Cooling lubricants and oils for the mechanic and pneumatic system of the machine have
to be adjusted referring the water added initially, the cooling lubricant emulsion and the
machining task.
We would like to ask you to have the following machine-related properties of the cooling lubri-
cant confirmed in writing by the manufacturer of the cooling lubricant.
The products need to comply with the current regulations of the law and of the employers

liability insurance association.
Request your manufacturer for cooling lubricants to submit you the documentation for the

products such as the product description VKIS and EC safety data sheet. The EC safety
data sheet gives you information about the water-hazard class.
They need to be environmentally friendly and working place-friendly. Thus, they need to be free
from nitrite, PCB, chlorine and nitrosinable diethanolamin (DEA), according to TRGS 611.
The manufacturer should be able to submit a certificate concerning skin-tolerance.

The mineral content according to DIN 51417 should be at least 40% in the concentrate.

If possible, it should be universally applicable for all chippings and materials.

Long service life of the emulsion e.g. long-term stable and resistant to bacteria.

Safe corrosion protection according to DIN 51360/2.

Re-emulsifiable and not sticking according to VKIS sheet 9: Sticking and residue behaviour.

It should not attack the varnish of the machine according to VDI 3035.

It should not attack any machine elements (metals, elastomeres).

Low foaming behaviour of the emulsion.

It should be as disperse as possible in order to avoid clocking-up at the needle slot screen.

11.2 Safety
WARNING!
The consequences of incorrect maintenance and repair work may include:
Severe injuries of persons working on the CNC machine,

Damage to the CNC machine.

Only qualified staff should carry out maintenance and repair work on the CNC machine.
