Abstract
A rotary chuck includes a clamp assembly, a first drive mechanism for operating the clamp assembly to clamp an associated workpiece, a frame rotationally fixed to the clamp assembly, and a second drive mechanism for rotating the frame and the clamp assembly. The second drive mechanism can rotate the frame and the clamp assembly around 360 degrees. A pair of alignment springs are engaged with a mounting plate upon which the second drive mechanism is mounted. The mounting plate can pivot relative to a stable surface to which it is mounted, and the springs limit the pivotal movement. Each first and second drive mechanism includes a motor, and are connected to a microprocessor for operation of the respective motor.
