DIAMOND GRINDER MAKING A DIFFERENT SIZE SCRATCH

摘要

A diamond grinding device forming scratch of various sizes is provided to enhance the abrasion efficiency and to easily recover the stiffness of the surface. A diamond grinding device(100) forming scratch of various sizes comprises: a particle region(33) in which a diamond particle(31,32) being stuck in a grinding tool main body(30); and a particle region having the diamond particle of same size or bagger. The particle region includes: a small particle region(34) having the most of the grinding tool main body; and a big particle region(35) having a majority part of the grinding tool main body. The small scratch of small size having shallow depth is formed on the pad surface with the diamond particle of the small particle region. The big scratch of big size with the deep depth is formed on the pad surface with the diamond particle of the large particle region.
