Chucks for machine tools and portable power tools -- Code of practice for the safe operation of workholding chucks used on lathes

PUBLISH DATE 1989

BSI BS 1983-5:1989

This Part of BS 1983 identifies and describes safe practices for design operation of workholding chucks used on turning machines.

The technical aspects covered by this code concern:

  1. the adequacy of the gripping force in the chuck;
  2. the fact that at excessive speed there may be failure of chuck components (fracture or excessive yielding);
  3. acceptable degrees of lack of balance and consequent vibration;
  4. the inertia loading imposed on the machine drive both by the chuck and by the workpiece;
  5. gravitational forces arising from the mass of the chuck and workpiece, together in some circumstances with cutting forces, and their effect on the machine;
  6. other aspects concerning the safe operation of lathe chucks.

Whilst primarily intended for application to lever and wedge type power chucks, including centrifugally compensated types, this code of practice can and should also be applied to manual chucks, but in such cases it is necessary to know the input torque.

NOTE 1 It should be recognized that even when a torque wrench or power driver is used, the grip is known to a lesser accuracy than, say, that of a power chuck having an hydraulically operated drawbar.

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
