Abstract: A workpiece is held between a movable clamping element (56) and a stationary clamping element (52). During setup, a hex drive (58) is rotated to move a traveler (100) which is connected to the movable clamping element along a threaded shaft (80). The threaded shaft is supported at one end through a spring retainer nut (88), a spring (86), and a bearing (82).
