5.7
Internal coolant supply
The internal coolant supply cools the tool and the HF spindle.
The tool coolant is routed internally through the HF spindle and tool, and
emerges at the interface of the clamped tool. The coolant lubricates the tool
at the same time.
Note: Unsuitable tool.
Tools without an internal hole are not suitable for internal coolant supply.
u
It is essential to switch off the internal coolant supply if tools without an
internal hole are being used for production reasons.
If this is not done, the HF spindle will be damaged or destroyed.
Ü
Only use tools and tool holders that are suitable for internal coolant sup-
ply.
Ü
Make sure that the cooling lubricant used conforms to the current specifi-
cations in legislation and from the trade associations.
5.7.1
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.
