The specified maximum speed of rotation stated only applies when
using the maximum clamping force and the SHB-type, soft, stand-
ard 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.
Ensure minimal weight for all jaws.
For unhardened top jaws or chuck jaws in special design, the permissi-
ble RPM according to VDI 3106 must be calculated for the respective
machining job. Whereby the recommended maximum speed must not
be exceeded. The values calculated must be checked by means of dy-
namic measurement using a clamping force tester.
