サイズのものと交換しておく。 The apparatus of the present invention configured as described above connects the negative side to the terminal of the tubular electrode 2 while flowing the required amount of electrolyte from the electrolyte inlet 11 toward the electrolyte outlet 12, and connects the negative side to the terminal of the tubular electrode 3 to be treated. While connecting the sides and applying a predetermined voltage, the tube material 3 to be treated is inserted into the hole of the sealing member 6 while pushing it outward as shown by the arrow in FIG. As the tube material 3 to be treated is gradually advanced, the inner circumferential surface of the soft porous tube 1 comes into sliding contact with the outer circumferential surface of the tube material 3 to be treated, and the electrolytic solution impregnated in the soft porous tube 1 flows into the tube material to be treated. It reacts with the outer peripheral surface of No. 3, and the contamination is removed by electrolytic polishing. In this case, the soft porous material pipe 1
The seal member 6 and the seal member 6 are replaced with one of the optimum size suitable for the pipe material 3 to be treated.

ない。 The electrolyte flows through the electrolyte passage 4, during which time it sufficiently impregnates the soft porous material tube 1, and the treated tube material 3 passes through the soft porous material tube 1 while its outer peripheral surface is rubbed.
Although it definitely comes into contact with the water, it does not flow unnecessarily.
