摘要
In an electropolishing method passing large current, an electrolytic solution is given a viscosity by reacting an organic acid (a phosphoric acid solution or a mixed solution of phosphoric acid and sulfuric acid) with a silicon dioxide as a gelling agent, the electrolytic solution is continuously introduced to an electrolysis case and concurrently the first introduced electrolytic solution is discharged to progress the electropolishing. The electrolysis case has a cathode at a specific height from a lower open end of a frame in a specific size and depth, an introduction port on the cathode for introducing the electrolytic solution with specific viscosity, and a discharge port for discharging the solution from the frame. It is possible to shorten the distance of the cathode in the electrolysis case from the open end corresponding to the work-piece surface, and control the resistant of the electrolytic solution, so that the large current can be passed and the operation time can be reduced.
