5.2.3 Calculation of the required clamping force at a given rotational speed

The initial clamping force

𝐹

𝑠𝑝0

is the total force applied to the

workpiece through the chucks when the clamping device is
actuated radially while stationary. Under the influence of ro-
tation, the chuck mass generates additional centrifugal force.
This centrifugal force decreases, or the initial clamping force
increases, depending upon whether clamping is applied from
outside inwards or from inside outwards.

The total of initial clamping force

𝐹

𝑠𝑝0

and total centrifugal

force

𝐹

𝑐

is the effective clamping force

𝐹

𝑠𝑝

.

𝐹

𝑠𝑝

= 𝐹

(-) for clamping from outside inwards

(+) for clamping from inside outwards

When tension is applied from outside inwards, the effective
clamping  force  decreases  as  rotational  speed  increases,
proportional  to  the  increase  in  centrifugal  force  [these  are
opposing forces]. When the limit speed is exceeded, the re-
quired  minimum  clamping  force

𝐹

𝑠𝑝 𝑚𝑖𝑛

is not achieved.

Consequently, the workpiece is released in an uncontrolled
manner.

DANGER

Serious injuries caused by projectile workpieces
when the limit speed is exceeded!



Never exceed the calculated rotational speed.



Never drop below the required minimum clamping
force.

In the following illustration, the reduction in effective clamp-
ing force is reduced by the total amount of centrifugal force
when clamping from outside inwards.
