ABSTRACT:
A longitudinally sectioned collet pad having plural pad segments of the detachable type, such as are conventionally used in an expansible collet, is provided with a freely interchangeable liner for each pad segment. Fastening means secure each liner against the inner surface of an outer member of the pad segment, and hold the liner against movement, either circumferentially, or radially inwardly.
Liners for each pad segment are provided with a roughened inner surface, preferably with serrations, to grip a bar of stock by coaction of the pad segments. Interchangeability of liners obviates the need for integral pad segments, permits the use of liners for a wide range of stock diameters using the same outer members of the pad segments, and effects great economy in the manufacture and use of removable collet pads.
