Note:
Masses of the jaw mounting screws and T-nuts are not taken
into account.
First the required effective clamping force F
sp
is calculated using
the machining force stated:
Initial clamping force during shutdown:
Calculation of total centrifugal force:
For two-part chuck jaws, the following applies:
Centrifugal torque of base jaw and top jaw specified in "Chuck da-
ta" table:
For the centrifugal torque of the top jaw, the following applies:
Centrifugal torque for one jaw:
The chuck has 3 jaws, the total centrifugal torque is:
The total centrifugal force can now be calculated:
Initial clamping force during shutdown that was sought:
