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.

Abstract: An improved method of forming a relatively thin elongated metal product is disclosed. In forming the product, a workpiece is first tensioned with a relatively high axial tension force and then is tensioned with a reduced axial tension force. The workpiece is supported against sidewise movement with a pair of rolls having outer side surfaces which engage the surface of the workpiece throughout the axial extent of a major portion of the workpiece. The thickness of the workpiece is reduced along at least a major portion of the workpiece while the reduced tension force is maintained and the workpiece is supported by the rolls. Although the method of the present invention could be utilized to form solid workpieces, it is particularly advantageous in forming tubular workpieces having thin wall sections with a thickness of 0.050 inches or less.
