Basic safety instructions
• Check the lathe chuck at least once per shift for externally
visible damage and faults.
Functional test
After installation of the lathe chuck, its function must be checked
prior to start-up:
•
Clamping force!
At max. torque, the clamping force specified
for the chuck must be reached.
•
Indicator pin!
Never clamp or switch on the lathe when the
indicator pin is protruding. (Golden pin on the chuck's shell).
•
Jaw lock!
The spindle can only be turned when all the chuck
jaws have been fitted into the T-slot. This prevents the wedge
bars from being brought into the working position without
chuck jaws.
Speed of rotation
DANGER
Possible risk of fatal injury to operating personnel if the chuck's
top speed is exceeded and a workpiece is released or parts fly
off.
If the machine tool or technical equipment can reach a higher
speed than the chuck's top speed, a reliable speed limiter must
be installed and proof must be provided that the speed limiter is
effective.
WARNING
Vibrations caused by the processing can result a loss of
clamping force. Risk of injury due drop out of the workpiece.
Manually operated chucks can lose clamping force because of
vibration which is caused by the processing of the workpiece.
•
Tighten the chuck regularly during processing to compensate
the loss of clamping force due to vibration.
Maintenance instructions
The manual chuck's reliability and safety can only be guaranteed if
the operator complies with the manufacturer's maintenance
instructions.
• For lubrication, we recommend our tried and tested special
grease, LINOMAX plus. Unsuitable lubricants can have a
negative impact on the functioning of the chuck (clamping
force, coefficient of friction, wear characteristics).
(For product information about LINOMAX plus, see the
"Accessories" chapter of the SCHUNK lathe chuck catalog or
contact SCHUNK.)
