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)

 [

}

 22]

" 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

Pneumatic tool change

For guidelines on air quality,
see "Air purity classes (ISO
8573-1)

 [

}

 22]

" section.

The tool change or tool taper change is performed pneumatically.

During this, a mechanism is operated inside the HF spindle which clamps, re-
leases, or ejects the tool taper or collet.
