Item no. 13201050, Revision 02 11 ( 32 )
5.3 Cooling
The HF spindle does not feature built-in cooling. However, this means that it
has a lower power than an HF spindle with cooling.
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.
u Dissipate the heat using the spindle holder.
5.4 Sealing air
For guidelines on air quality,
see "Air purity classes (ISO
8573-1)
[
}
20] " 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.
