For the ROTA-S flex chucks it's necessary to
determine those data specific. Calculation
examples are in the chapter "Technology" in
the SCHUNK-lathe-chuck-catalog or in the
chapter "Special jaws/Technology" in the
SCHUNK-power-chuck-catalog. Those catalogs
are also available as download at
www.de.schunk.com.
The recommended max. speed is only valid for max. operating
force and the use of the suitable hard standard stepped jaws.

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.
The recommended speed is valid for ROTA-S flex with long base
jaws and SCHUNK stepped block jaws, hard, type STF.
In this the base jaws are inserted flush with outer diameter of the
chuck.
