Technical descriptionItem no. 10402003, Revision 0212 ( 40 )5.3 CoolingThe HF spindle does not feature built-in cooling. However, this means that ithas 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 theHF spindle should not exceed + 45° C as this shortens the service life of thebearing.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 holderExample of design:Air-cooled spindle holderExample of design:Liquid-cooled spindle holderTo 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 Alfred Jäger 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 [} 14] 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 surfaceof the spindle holder.
