Cleaning the silencer:
Interval Demands
every 2 months Clean the silencer, if necessary in case of
severe contamination replace the silencer
Please regularly check the lathe chuck for tightness by applying a
clamping force tester over a longer period of time (> 10 min.). The
clamping force should not drop during this period. Please adjust
the inspection interval to the operating conditions of the clamping
device. We recommend conducting a check every 5,000 clamping
cycles at the latest however.
Hardened Reversible Jaws and Soft Top Jaws
The fine serration of the base and top jaws for sizes 470 – 1000 is
3/32" x 90°, so the adjusting stroke from tooth to tooth is 2.4 mm.
Care must be taken to ensure that the top jaws are set on the
fine serration in such a way that a maximum of 2/3 of the jaw
stroke is extended for clamping (clamping reserve).
With long stroke chucks, ensure that the indicator pin is
completely recessed or that the correctly configured path control
releases the clamping.
Hardened reversible jaws should only be used in sets in
accordance with the packaging, as they are ground on the chuck in
sets. 1 set of hardened reversible jaws is normally ordered for a
chuck. When installing and removing the reversible jaws
numbered 1 to 3, make sure that the individual jaws are
installed/removed on/from the base jaws with the same
designation in order to ensure a high level run-out accuracy.
The soft top jaws are turned on the chuck in the same clamping
position and under the same operating pressure as are used for
machining the workpiece. When doing this, it is important to
ensure that all the mounting screws are screwed in tightly and
evenly.

The fine serration of the base jaws and top jaws should always be
cleaned, especially when the top jaws are adjusted, otherwise the
run-out accuracy will be impaired. Hardened reversible jaws and
soft top jaws must be tightened to the same torque. Insufficient
tightening of the top jaws will cause significant run-out
inaccuracies!
