Maintenance and care
The quick-change pallet system is designed for low-maintenance
operation so that opening and disassembling the clamping
modules is only necessary in exceptional cases.
The service life of the clamping system depends on the number of
clamping cycles and the operating conditions.
The pull-down force must be measured after every 3000 operating
hours. If the pull-down force is less than 36 kN, the actuating
piston must be greased as described below. If the pull down force
remains below 36 kN after greasing, the module is due for a
complete service.
A maintenance interval must be carried out after every 50,000
clamping cycles. This involves greasing the actuating piston (item
11). To lubricate, the module must be in the open clamping
position (clamping slide inside). Remove the ventilation set-screw
(item 48) and fill the special grease LINOMAX plus with the grease
gun via the lubrication nipple (item 47) until the grease oozes out
of the ventilation hole. Thereafter actuate (close and open) the
module several times (3-5 times); this will push the excess grease
out of the ventilation hole. Remove the excess grease.
Then close the ventilation hole with the ventilation set-screw (item
48).
After every disassembly operation, each quick-change pallet
system must be ventilated.
The clamping rings must be inspected for wear in the area of the
clamping slides (item 2). In case of heavy wear or after 100,000
clamping cycles, the clamping ring must be replaced or turned 30°.
To do this, the fastening screws must be loosened and the
clamping ring turned 30°. Tighten the fastening screws to the
specified torque after turning the clamping ring.
After every 250,000 clamping cycles, all visible wear parts must be
inspected visually and the system must be checked for leakage.
To replace wearing parts, the quick-change pallet system must be
removed from the machine and disassembled, the wearing parts
exchanged and the machine reassembled by appropriately trained
personnel using special tools (calibration rings, calibration
mandrels, etc.).
After every disassembly operation, each quick-change pallet
system must be ventilated.
Only genuine SCHUNK spare parts may be used.
