Device and method for electropolishing by means of a conductive surface

A device for electropolishing by means of a conductive surface which, applicable for polishing the surface of a metal part (2), comprises:

• a power source (3);
• an electrode (4);
• a conductive surface (1);
• a system that provides electrical connectivity to the metal part (2) to be polished at a pole of the power source (3);
• a system that provides electrical connectivity to the conductive surface (1) at the opposite pole of the power source (3);
• and
• a system that provides relative movement of the conductive surface (1) with respect to the metal part (2) to be polished,
• wherein the electrode (4) contacts one side of the conductive surface (1) and the part (2) to be polished can be brought into contact with the conductive surface (1) on the other side, such that a polishing effect occurs when the power source (3) applies a potential difference between the part (2) to be polished and the electrode (4),
• characterized in that the conductive surface (1) is manufactured with a non-conductive material that retains a conductive liquid solution, such that the conductive surface has an electrical conductivity that can be measured between the two sides of the material.
