5.5.1
Cooling lubricant
Ü
Do not use pure or distilled water.
Ä
Such water causes immediate corrosion on bare parts, which is often un-
noticeable at first, but later leads to serious corrosion damage.
Ü
Only use cooling lubricants that comply with the following guidelines:
Corrosion protection in accordance with DIN 51360 Part 2:
No corrosion after 2 hours.
Compatibility with elastomers:
No change to Shore hardness values or elongation
Compatibility with non-ferrous metals:
No damage to copper, brass, or aluminum parts
Adhesive residue behavior after slow evaporation at 50°C:
Not adhesive.
No “adhesive tape effect”
Easily resoluble or re-emulsifiable.
5.5.2
Filtering the cooling lubricant
Unfiltered flow media with a particle size in excess of 50 µm lead to increased
wear.
Ü
Use a filter upstream of the internal coolant supply that filters out particles
that are bigger than 50 μm from the medium.
The greater the number of particles in the flow medium, the greater the wear
on the internal coolant supply.
