Lubrication
To maintain the safe function and high quality of the chuck, it has
to be regularly lubricated at the lubrication nipples. Use SCHUNK
LINO MAX special grease for this purpose.
• For optimum grease distribution, the clamping piston must
travel the entire clamping stroke several times after lubrication.
Operating conditions:
Depending on the operating conditions, the function and clamping
force must be checked after a certain period of operation
(
9.2, Page 26)
. The most accurate way to measure the clamping
force is with a clamping force tester.
Technical condition:
When the smallest possible actuating pressure is applied (clamping
cylinder), the base jaws must move evenly. This method only
provides a limited indication and does not replace measurement
of the clamping force.
• If the clamping force has dropped too far or if the base jaws
and clamping piston no longer move properly, the chuck has
to be disassembled, cleaned, and relubricated.
Only use genuine SCHUNK spare parts when replacing damaged
parts.
Maintenance intervals
Lubrication of the grease areas:
Lubrication interval Strain
every 25 hours
normal / coolant utilization
every 8 hours
high / coolant utilization
after 1200 hours or
as needed
Total cleaning with disassembly of the
chuck, depending on type and degree of
contamination
Changing the top jaws
When changing the top jaws the serration must be cleaned and
greased with SCHUNK special grease LINO MAX.
