ABSTRACT:
A lathe chuck jaw assembly utilizes top jaws which have replaceable inserts mounted to their clamping faces. The inserts are used to provide a contact surface to hold a workpiece during machining. The contact surfaces of the inserts may be machined for matching a particular workpiece shape such as round stock, hex stock, square stock, or custom configurations. A boring ring is installed between the top jaws and rotated so that the inserts may be symmetrically machined. Alternatively, a polygonal insert blank having congruent sections which are joined with keys along their outer sides may be loaded in the lathe chuck and machined for a particular workpiece. A pad adapter base for supporting a hardened collet pad is also disclosed.
