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.
Ü
Make sure that compressed air is not applied to the internal coolant supply
in the case of a rotating shaft. Otherwise, the sealing surfaces of the inter-
nal coolant supply will be damaged.
5.7.1
Cooling lubricant
CAUTION: Danger due to hydraulic oil spraying out.
If the internal coolant supply is used for hydraulic oil, the internal coolant
supply may be damaged and hydraulic oil may be sprayed out at high pres-
sure.
u
Do not use hydraulic oils.
Ü
Only use cooling lubricants that comply with the following guidelines:
Cutting oil
Temperature of the medium
min. +3°C
Ambient temperature
min. +3°C
