Clamping Force-Speed Diagram - Lathe Chuck K11-80 - Optimum Optiturn TU 2807VB Betriebsanleitung

DANGER!
Risk to life and limb of the operating personnel and significant property damage when
the RPM limit is exceeded! With gripping from the outside inwards, and with increasing
RPM, the effective clamping force is reduced by the magnitude of the increasing
centrifugal force (the forces are opposed). When the RPM limit is exceeded, the
clamping force drops below the minimum clamping force F
workpiece is released in an unchecked manner.

Do not exceed the calculated RPM.

Do not fall below the necessary minimum clamping force.

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 diam-
eter of the chuck.
