COMPENSATING WORKHOLDING EQUIPMENT

摘要

Workholding equipment for a machine tool, in particular an arbor chuck (2), having a plurality of internal elements comprising a wobble washer (26) and at least one of a floating nut (24) and flat washer (28) which counteract workpiece misalignment. In arbor chucks, the wobble washer and floating nut counteract misaligned pulling forces due at least in part to the lead angle of threads (15) on an expander (14) of the arbor chuck.
