ABSTRACT:
A collet chuck holder is described in which a standard collet is threaded into a retaining ring which is firmly fastened to the inside of a chuck body. A push tube inside the chuck is joined by bolts to a closing sleeve which surrounds the collet; these bolts pass through oversize holes in the collet retaining ring so that forces exerted by the push tube affect only the closing ring and are not transferred to the collet retaining ring. Unlike the draw bar action normally applied to collet operation, there is no axial displacement of the workpiece. This feature is useful where axial displacement would cause errors in the machining operation.
