Abstract
PURPOSE:To polish the inner surface of a tube without moving a plate terminal and without providing many electrode terminals even when the position of the following coiled electrode is optional with respect to each inner surface of a tube by using a tubular work as the anode, arranging the coiled electrode in the tube as the cathode, and carrying out electrolysis in an electrolyte. CONSTITUTION:A cathode is arranged in a straight or bent-tube work 3, and the inner surface of the work 3 is electropolished in the electrolyte 2 by using the coiled electrode 5 as the cathode. When the electrode 5 is energized, a magnetic flux is generated in the direction orthogonal to the cross section of the coil, the magnetic flux is generated all over the inner surface of the work 3, an ion is eluted from the work 3, and an anolyte layer is formed all over the inner surface of the work 3. Namely, the anolyte layer is formed all over the inner surface irrespective of the shape of the work 3 and the position of the cathode in the work 3, and the inner surface of the work 3 is polished, lustered, and smoothed. In addition, the electrode 3 is inserted in an electrical insulating tube 4 having wetted holes 6 on the periphery, the assembly is inserted in the work 3, and electrolysis is satisfactorily carried out.
