The recommended rotational speed applies to the clamping jaws tiered on the inside that are
delivered with the lathe chuck which finish flush with the external chuck diameter.
4.12.5 Replacing the clamping jaws on the lathe chuck
CAUTION!
The correct position of the clamping jaws is correct if after twisting together of the
chuck jaws are centered at the center.
The clamping jaws and the three-jaw chuck
are equipped with numbers. Nevertheless
check before the change, if the numbers are
readable - if necessary - check the jaws and
their original position. Insert the clamping
jaws at the correct position and in the right
order into the three-jaw chuck. Do not con-
fuse additional markings on the lathe chuck
with number sequences.
