Maintenance and care for WDA 99-79-32 hydraulic
compensation module
Only store the hydraulic expansion toolholder when it is not
clamped and make sure to protect it from corrosion.
• To secure the clamping forces with every clamping pin change,
clean the clamping bore and the screw-shaped groove with a
cleaning agent containing solvents.
• For storage, lightly oil the entire surface of the hydraulic
expansion toolholder.
It may be necessary for it to be cleaned according to the ambi-
ent conditions, especially in the case of high clamping frequen-
cies, high operating temperatures, or abrasive dirt or metal
clips and metal particles.
Repair work is only allowed to be carried out at a SCHUNK site.
Ambient conditions and operating conditions
• Make sure that the contact surfaces of the interface are always
clean.
• Always ensure that no chips of any kind enter the interface of
the change components.
• Only use high-quality cooling emulsions with anti-corrosive
additives during processing.
• Check the pneumatic clamping systems and the workpiece
direct clamping modules at regular intervals (at least every
2 weeks or after 200 clampings).
• Carry out regular visual/functional checks.
In the case of visible damage or signs of malfunctions on the
clamping systems or the quick-change pallet system installed with
the WDN 99-70 workpiece direct clamping module, shut down the
clamping systems immediately. The system may only be commis-
sioned again once the faults have been corrected. For example, by
replacing the damaged module.
