lubricant back to the surfaces of the force transmission. This
means that the clamping force is retained for longer).
Caution
Following a longer shutdown period (more than 6 hours), always
retension the clamped lathe chuck in order to compensate for the
setting properties of the clamping situation or possible pressure
losses and the resulting loss of clamping force.
Safety notes for servicing
Follow all the applicable legal norms for health and safety during
servicing. Use suitable personal protective equipment, especially
protective gloves, goggles and safety boots, paying particular
attention to the operating system and hazard assessment.
DANGER
Possible risk of fatal injury to operating personnel due to chuck
failure if the servicing instructions for the chuck are
disregarded!
The servicing instructions specified by the manufacturer must be
complied with to ensure safe operation of the chuck.
Work must be carried out by qualified specialist personnel with
the relevant safety training.
Use of special chuck jaws
When using special chuck jaws, please observe the following rules:
• The chuck jaws should be designed to be as light and as low as
possible. The clamping point must be as close as possible to the
chuck face (clamping points at a greater distance lead to
greater surface pressure in the jaw guidance and can
significantly reduce the clamping force).
• Do not use welded jaws.
• If for constructional reasons the chuck jaws in special design
are heavier than the top jaws assigned to the clamping device,
greater centrifugal forces must be accounted for when defining
the required clamping force and the recommended speed.
• Screw the jaw mounting screws into the bore holes furthest
apart.
• The maximum recommended speed may only be operated in
conjunction with maximum actuating force and only with the
chuck in optimal, fully functioning condition.
