Commissioning and maintenance
Initial operation
Check whether the jaw guides and the piston of the ROTA TPS
power chuck are sufficiently lubricated at the lubricating nipples
embedded in the base jaws.
If required, lubricate the chuck with the base jaws retracted, by
using LINOMAX special grease from SCHUNK.
NOTICE
An insufficiently lubricated chuck will result in a significantly
reduced clamping force.
Turning, facing or skimming of the front-end power chuck is not
permitted.
Drilling of the chuck on the front face side may be performed only
after consulting the SCHUNK technical sales department.
Hardened Reversible Jaws and Soft Top Jaws
Fine serration of the base and top jaws is 1/16" x 90°. The
adjusting stroke from tooth to tooth is approximately 1.6 mm.
NOTICE
It must be ensured that the top jaws are fixed on the fine
serration in such a way that a maximum of 2/3 the jaw stroke is
extended for clamping.
Hardened reversible jaws should only be used in sets in
accordance with the packaging, as they are manufactured on the
device in sets. 1 set of hardened reversible jaws is normally
ordered for a power chuck.
When installing and removing the reversible jaws numbered 1 - 3,
make sure that the individual jaws are installed/removed on/from
the base jaws with the same designation to ensure a high level of
accuracy of the clamping center.
The fine serration of the base jaws and top jaws should always be
cleaned when the top jaws are adjusted, because otherwise the
true running accuracy will be reduced.
The screws of the hardened reversible jaws and soft top jaws must
be tightened with the specified torque.
