Notes on safe operation
•
The machine spindle may only be started up when clamping
pressure has built up in the cylinder and clamping has followed
in the permitted work area.
•
Unclamping may only be possible when the machine spindle
has come to a standstill.
•
If the clamping energy fails, the workpiece must remain firmly
clamped until the spindle is shut down and the workpiece is
secured.
•
The technical safety requirements in the respective operating
instructions must be observed exactly.
Functional test
After installation of the chuck, its function must be checked prior
to start-up.
Two important points are:
•
Clamping Force!
The clamping force of the chuck must be
achieved at max. operating force/pressure.
•
Stroke control!
The stroke of the clamping piston must allow a
safety zone at the front and rear end position. The machine
spindle may only be started when the clamping piston has
passed through the safety zone. Only limit switches that meet
the requirements for safety limit switches specified in DIN EN
60204-1 may be used.
When determining the necessary clamping force to machine a
workpiece, take the centrifugal force acting on the chuck jaws into
account (according to VDI 3106).
If the chuck jaws are changed, adjust the stroke control to the new
situation.
Speed
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.
