PURPOSE:To improve the durability while to lengthen the service life and to provide the rigidity sufficiently for independent use, by making the angle between many micro teeth and the side face smaller than 90 deg.. CONSTITUTION:A metallic polishing member 1 to be employed when polishing the surface of a non-metallic and metallic material to be polished is constructed with a metallic base material 2 and integrally formed teeth 3. In other word, many micro metallic teeth 3 are formed integrally on at least one surface of said material 2. Each tooth 3 is equipped with a top face 4 and a side face 5, where the top face 4 can contact with the material to be polshed while an edge section 6 is formed at the interface of said faces. The angle between the top face 4 and the side face 5 or the cutting angle (s) is set to 40-70 deg.. Consequently the durability, long service life and the rigidity sufficient for independent use can be provided easily. |
