4.25.5 Clamping force-speed diagram - Lathe chuck K11-160

Speed n [rpm]
The clamping force to speed diagram shows the calculated centrifugal force with the matching
jaw design as a function for the speed if the chuck jaws do not protrude beyond the outer dia-
meter of the chuck.

4.25.6 Clamping jaw centrifugal force

To calculate the required tensioning force for processing a workpiece, the centrifugal force of
the clamping jaws must be taken into account.
The permissible speeds can be determined in accordance with VDI Guideline 3106 "Determi-
ning the permissible speed for lathe chucks (jaw chucks). This guideline also allows for the resi-
dual tensioning force at a specified speed to be determined.
