ABSTRACT:
The chuck disclosed has a work-gripping collet at the longitudinal axis thereof which is surrounded by front and rear annular slides that are spring biased in an axially forward direction. The slides are independently shiftable axially. The inner peripheral surface at the front end portion of the front slide and the inner peripheral surface at the rear end portion of the rear slide are inclined radially inwardly and axially rearwardly to correspond with the inclination of the outer surface of the externally tapered workpiece. The workpiece is telescoped rearwardly over the collet so that its external surface is first engaged by the inclined surface on the rear slide and then by the inclined surface on the front slide. After the leading end of the workpiece engages a part stop on the chuck the collet is shifted rearwardly to firmly grip the workpiece.
