Fig. 3: Unclamping length
■ Unclamping length (L
which may be machined without the support of a bezel or tailstock is
a maximum of 5 times the clamping diameter (D
■ Clamping length (L
chuck without the support of a bezel or tailstock must not be less than
half of the clamping diameter (D
10 mm .
Examples:
D = 40 mm ==> min. L

Fig. 4: Clamping length
The maximum weight of the part to be clamped depends on the geometry
and the chuck size. The necessary clamping force must always be
calculated in accordance with the valid standards and directives. Failure to
observe this may lead to serious accidents due to clamped parts coming
loose!
