2.8 clamping force
Jaw clamping force
Clamping forces in Table 7 are with the jaws lubricated according to the directions contained under item 2.7.
2.9 admissible revolutions
Admissible revolutions of the chuck depend on many factors, such as cutting parameters, weight of the workpiece
and its balance or type of machining (interrupted or continuous turning) etc.
The max. speeds as indicated in the table below should not cause a decrease of the clamping force to the half
of its initial value. When machining in the stable conditions (machining material, tools, working conditions), the
clamping force may be reduced by up to 67% of its initial value.
This relate to the chuck equipped with standard jaws, that do not protrude beyond the outer diameter of the chuck
and the unbalance condition of the ‘chuck-machining workpiece’ is maintained (not exceeding 20gmm/kg). The
chuck and jaws must be in good condition. Otherwise, refer to the calculations as indicated in the PN-M-60650.
