Ensure minimal weight for all jaws.
For the respective machining task, the permissible speed of
rotation for a given initial clamping force or the required clamping
force for a given speed of rotation must be calculated according to
VDI 3106, whereby the maximum speed of rotation or the
maximum clamping force of the lathe chuck must not be
exceeded. The calculated values must be checked by dynamic
measurement. Functional monitoring must be performed
according to the guidelines of the insurance association.
