ABSTRACT:
The chuck disclosed has three radially movable jaws for gripping and releasing a workpiece. The jaws are displaced radially by means of a draw-bar actuated puller plate coupled to the inner ends of inclined, radially extending rods on which the jaws are mounted. The puller plate is swivelly coupled to the drawbar and to the jaw rods to enable the jaws to firmly grip a workpiece around a surface which is not concentric to a previously machined centering surface on the workpiece and by means of which the workpiece is positioned on the chuck. Means are provided for optionally preventing swiveling movement of the puller plate.
