Maintenance intervals
Lubrication of the grease areas:
normal / coolant utilization
high / coolant utilization
as needed
Total cleaning with disassembly of the
chuck, depending on type and degree of
Hardened Reversible Jaws and Soft Top Jaws
Make sure that the top jaws are set for clamping on the fine serration
so that no more than 2/3 of the jaw stroke has to be extended
(clamping reserve).
Hardened reverse jaws may be used only in sets as packaged at
the factory, since they are ground in sets on the chuck. Normally,
one set of hardened reverse jaws is ordered with the chuck. During
assembly and disassembly of the reverse jaws numbered 1 to 3
make sure that the single jaws are paired with the base jaws with
the same numbers in order to achieve good true running properties.
Turning of the soft top jaws must be performed on the chuck in
the same clamping position and at the same operating pressure
specified for machining of the workpiece.
Hardened roughing jaws whose clamping surfaces have conical
teeth with good grip should be used for rough turning work or
preturned workpieces.
