Since the size 65 clamping head chuck can exert a maximum
radial clamping force of ��
ciple 1.
In this example, Principle 2 does not apply because work is
performed without a tailstock in this case.
Principle 3 would also be satisfied, because the calculated
cutting force of ��
= 1226�� is well below the limit of ��
��
5000��.
On the other hand, Principles 4 and 5 are immaterial in this
example because both principles only need to be considered
in relation to radial drilling operations.
Result of the sample calculation
All limits have been checked.
The axial actuation force is proportional to the radial clamp-
ing force and interpolation can therefore be used to deter-
mine this on the basis of the values for ��
as indicated on the clamping head chuck, or you can consult
