NOTICE
Make sure that the workpiece is clamped halfway up the base
jaw stroke.
The workpiece must not be clamped at the end of the base jaw
stroke. This can lead to the workpiece becoming loose.
6.4 Functional testing
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.
DANGER
Risk of fatal injury to operating personnel if the top speed is
exceeded, resulting in workpiece loss and parts flying off!
•
A reliable speed limiter must be installed in the machine tool
or technical equipment and proof must be provided that the
speed limiter is effective!
