5.4
Sealing air
For guidelines on air quality,
see "Air purity classes (ISO
8573-1)
" section.
The sealing air prevents foreign bodies such as chips and liquids (e.g. emul-
sions) from entering the HF spindle.
Ü
Check that air escapes at the front between the housing and the rotating
parts of the HF spindle.
5.5
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.
