Abstract: The fundamental experiment of the grinding of the stainless steel using the metal bonded CBN wheel which was excellent in wear resistance was conducted. The most appropriate grinding conditions were obtained by clarifying wear process of grinding wheel and finished ground surface quality. When grinding was carried out up to stock removal 7000mm3/mm, radial wear of grinding wheel %R is 3μm and surface roughness Rz was 0.5μm or less. The grinding ratio Gr becomes about 3000, and long life grinding with little change of surface roughness was possible.

Abstract: In this study, the influences of carbides and alloy additives on ground surface characteristics of several high Chromium (Cr) steels and abrasive grains of working surface were discussed. In the grinding using metal bonded CBN wheel, almost constant values in ground surface roughness and high grinding ratio were shown. 5% Cr steel with Vanadium, 8% Cr steel and 10% Cr steel showed a rougher surface than Cr steels with 3%, 4% and 5% due to the carbide inclusion. The grinding ratio of 5%Cr steel could be raised considerably by adding sulfur to it.
