Clamping force-speed diagram - Lathe chuck K11-200
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 diam-
eter of the chuck.
7.7
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 "Determin-
ing the permissible speed for lathe chucks (jaw chucks). This guideline also allows for the resid-
ual tensioning force at a specified speed to be determined.
