• Machining force F
spz
= 3000 N (application-specific)
• max. RPM n
max
= 3200 RPM ("Lathe chuck data" table)
• RPM n = 1200 RPM (application-specific)
• Mass of one (!) top jaw m
AB
= 5.33 kg (application-
specific)
• Center of gravity radius of top jaw r
sAB
= 0.107 m (application-
specific)
• Safety factor S
z
= 1.5 (according to VDI 3106)
• Safety factor S
sp
= 1.5 (according to VDI 3106)
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:
Take the centrifugal torque of the base jaw and top jaw specified
from the "Lathe chuck data" 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:
