Zusammenfassung: | PROBLEM TO BE SOLVED: To make it possible to perform excellent mirror surface finishing on the outer periphery surface in such manner as not to give a surface defect and to improve the dimensional accuracy and the product yield by combining a centerless polishing and an electrolytic composite polishing. SOLUTION: A long-sized aluminum or aluminum alloy pipe Q which is finished to a prescribed dimensional accuracy and has a surface roughness below 10 μm is cut to a specified length after centerless polishing and is subjected to polishing with a cylindrical outer electrolytic composite polishing device 4 having a tool electrode mechanism equipped with special elastic grinding wheels 8, there the pipe Q is finished below |
