5.3
Cooling
Liquid cooling keeps the HF spindle at a constant temperature during opera-
tion.
Note: Extension of the service life through heat dissipation.
Heat is produced during operation of the HF spindle. The temperature of the
HF spindle should not 45° C as this shortens the service life of the
bearing.
u
Check the temperature of the HF spindle on the housing.
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.
