PURPOSE:To finish the surface of a stainless steel pipe to excellent mirror surface efficiently. CONSTITUTION:As a preparatory step of the finishing polish for finishing a stainless steel pipe 2 to a mirror surface, a brush 1 made of synthetic resin, which is mainly composed of meta group aromatic polyamide and which is contaminated with grinding grains, is used, and the center of rotation of the brush 1 is inclined at 5-25 degree against the moving direction of the stainless steel pipe 2 or the brush 1, and the brush 1 is rotated to polish the stainless steel pipe 2. The stainless steel pipe 2 can be polished to a mirror surface with few passes by setting the angle of inclination of the brush 1 at 5-25 degree. The surface of the polished stainless steel pipe 2 is finished at a degree of smoothness, of which surface roughness Rmax=0.1mum, without flaws such as scratches and polishing mark. |
