ABSTRACT:
A dual position chuck and turning machine method allow automatic shifting of a workpiece from a first to a second turning axis by actuation of a draw bar through the spindle of the turning machine. A linkage in the chuck drives a movable jaw assembly having peripheral fixed keys thereon in an arcuate keyway responsive to the draw bar movement. The arcuate keyway allows moving the workpiece to second axes which are not merely rotations of the jaw assembly.
