The recommended max. r.p.m. is only valid for max. operating
force and the use of the suitable hard standard stepped jaws.
WARNING
Danger of personal injury and property damage caused by flying
parts in case of spiral fracture of soft top jaws!
Soft standard top jaws must be hardened at the area around the
countersink.
They should only be depth-hardened, not surfacehardened.
When using unhardened top jaws or jaws in special design, make
sure that their weight is as low as possible.For soft top jaws or
jaws in special design the permissible speed of the respective
cutting task has to be calculated in accordance to VDI 3106,
whereby the maximum standard value may not be exceeded.The
calculated values have to be examined with a dynamic
measurement.Control of function (piston movement and actuation
pressure) has to be accomplished in accordance with the
guidelines of the professional association.
