7.0 Commissioning
7.1 Notes
The initial period of use has a marked effect on the satisfactory performance of the power chuck. The
mounting of the power chuck should be checked at this stage.
Mount the top jaws centrically and then connect to the master jaws (observe the marks
on the chuck body and master jaw)!
Do not overload the power chuck! Set the pressure at the actuating cylinder so that the
maximum permissible actuating force is not exceeded!
(See section
Design and function - Technical data)
•
The power chuck must open and close at approx. 1/10 of the permissible actuating force!
•
Binding of the power chuck may be the result of strained master jaws or top jaws. Unbolt the top
jaws and inspect the cross tenon.
•
If the power chuck binds without top jaws, the chuck body may be strained. Check the flatness
of the chuck mounting flange!
•
Check the jaw movement and chuck piston stroke!
•
Check the gripping force Fsp0 with a static gripping force meter, e.g. SKM 1200 / 1500
The stop of the cylinder piston is on the right, always in the actuating cylinder - not in the
power chuck.
The extent of movement of the chuck piston towards
the left must be limited by the chuck body or its
mounting flange.
