The specified maximum speed of rotation stated only applies when
using the maximum clamping force and the SHB-type, hard,
standard stepped jaws that go with the chuck.
WARNING
Risk of personal injury and property damage due to parts flying
off in the event of a screw breakage on unhardened top jaws!
Soft standard top jaws must be hardened in the countersink
region.
They should only be depth-hardened, not surface-hardened.
If unhardened top jaws or chuck jaws in a special design are used,
ensure that the jaws weigh as little as possible. For soft top jaws or
chuck jaws in special design, the permissible speed of rotation
according to VDI 3106 must be calculated for the machining job in
question. The recommended maximum speed must not be
exceeded. The calculations must be checked using dynamic
measurement. Function monitoring (piston movement and
actuating pressure) must be performed in accordance with the
guidelines of the Berufsgenossenschaft (employers' mutual
insurance association).
