Functional testing
Functional test
After installation of the chuck, its function must be checked prior
to start-up. Make sure there are no leaks in the line system.
Two important points are:
•
Clamping force!
At max. actuating force/pressure, the clamping
force specified for the chuck must be reached.
•
Stroke control
The stroke of the clamping piston must have a
margin of safety at the front and back end positions. The
machine tool must not start up until the clamping piston has
passed through the safety margin Only limit switches that meet
the requirements for safety limit switches specified in DIN EN
60204-1 may be used to monitor the clamping path.
If the chuck jaws are changed, adjust the stroke control to the new
situation.
