The maximum RPM stated is only valid with the maximum clamp-
ing force and when using the hard standard chuck jaws that go
with the chuck.
If unhardened top jaws or special chuck jaws are used, ensure that
the jaws weigh as little as possible.
For soft top jaws or special chuck jaws, the permissible speed of rota-
tion according to VDI 3106 must be calculated for the machining job
in question. The recommended maximum speed must not be ex-
ceeded. The calculations must be checked using dynamic measure-
ment. Function monitoring (piston movement and actuating pres-
sure) must be performed in accordance with the guidelines of the
Berufsgenossenschaft (employers' mutual insurance association).
