Abstract
An electropolishing system including an anode, a cathode, a rolling block and a motion controller. The anode is configured to removably retain a metal device to be electropolished, and may be formed as a bar made from a solid cylindrical piece of metal or other configurations, such as wires with hooks. The anode transfers the electricity to the metal device while grooming the surface of the metal device as it contacts the rolling block. The cathode may be configured as a mesh and completes the electrical circuit. The rolling block is formed from a relatively smooth, solid material and positioned so as to allow the metal device to roll against the surface of the block. The motion controller is configured to provide vertical and horizontal movement of the anode and metal device, using force transducers to control the compression of the metal device against the rolling block.
