Jäger Z45-D160.05 S3 Manual

Technical descriptionItem no. 10301100, Revision 01 13 ( 40 )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 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 [} 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.5.4 Sealing airFor guidelines on air quality,see "Air purity classes (ISO8573-1) [} 24]" 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 rotatingparts of the HF spindle.5.5 Taper cleaningTaper cleaning prevents chips and liquids from entering the shaft during atool change and causing contamination and damage to the inner taper andthe clamping system.The taper cleaning is integrated in the pneumatics system for the tool change.This means that no additional connections are required.q Blow air through collet during tool change5.6 Pneumatic tool changeFor guidelines on air quality,see "Air purity classes (ISO8573-1) [} 24]" 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.
