Abstract

The present invention pertains to a device for controlling polishing assembly movement. The device comprises a vertical rod, a motive power means for lowering and lifting, and rotating, oscillating, or both rotating and oscillating the vertical rod about an axis of rotation coaxial with the vertical rod. The device also comprises a pin that is offset from the axis of rotation and connected to the vertical rod for mounting the polishing assembly. Optionally, the device may comprise a sensor for activating movement of the vertical rod.
