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.

5.3.1

Cooling via spindle holder

Example of design:

Air-cooled spindle holder

Example of design:

Liquid-cooled spindle holder

To  increase  the  power  of  the  HF  spindle,  the  heat  generated  must  be  dissi-
pated via the spindle holder (optional accessory).

If the spindle holder is to be produced in-house:

Ü

Contact 

Nakanishi Jaeger GmbH

.

Ü

Request the tolerances and production plan for the spindle holder.

Ü

Produce the spindle holder from a thermally-conductive material (e.g. alu-
minum).

Ü

Observe the dimensions of the clamping range in the Technical Specifica-
tions

 [

}

 12]

 section. Make sure that the HF spindle is enclosed by the spin-

dle holder to the specified length.

Ü

Add cooling fins or holes (greater heat dissipation) to the external surface
of the spindle holder.

5.4

Sealing air

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

 [

}

 21]

" 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.
