4.13.5 Lathe chuck maintenance
A crucial prerequisite for fault-free functionality of a lathe chuck is regular and thorough lubrica-
tion of the sliding surfaces. This prevents the reduction of tensioning force and premature wear
and tear.
Always observe the manufacturer's maintenance instructions when using replacement lathe
chucks.
Coolant squirts on the lathe chuck and removes the grease from the jaws. In order to maintain
the tensioning force and the long-term accuracy of the lathe chuck, the lathe chuck must be
lubricated regularly. Insufficient lubrication will result in malfunctions with significantly reduced
tensioning force, which affects the accuracy and causes excessive wear and seizing.
Lubricate the installed lathe chuck at least once per week. The used lubricant should be of high
quality and provided for high pressure bearing surfaces. The lubricant should withstand the
coolant and other chemicals.
We recommend the use of ALTEMP Q NB 50 by Klueber for the lubrication of the sliding sur-
faces and clamping fixture of the supplied lathe chucks. You may optionally use a lubricant for
lathe chucks from other renowned lathe chuck manufacturers.
Clamping jaws and jaw mounting screws are wear and tear parts. The service life is limited. We
therefore recommend having them inspected at regular intervals by a specialist (e.g. inspection
for cracks using a dye penetration process or magnet powder test (fluxing), eddy current test-
ing, ultrasound testing) and replace if necessary.
4.13.6 Clamping long workpieces
through the hollow shaft of the spindle
CAUTION!
Long rotating parts that protrude from the hollow shaft of the spindle must be secured
by the operator using suitable covers. A cover can be a sleeve that is mounted on the
headstock that, as a permanent safety device, completely covers the protruding
workpiece.
between the tips
CAUTION!
Long workpieces must be additionally supported. They are supported by the tailstock
sleeve and, if necessary, a rest.
with a lathe dog
CAUTION!
When clamping workpieces between the tips of the lathe while using a lathe dog, the
existing lathe chuck protection must be replaced with a circular lathe chuck protection.
