This paper deals with the relationship between the uniformity in wheel structure and the grinding performance in vitrified bonded CBN wheels. We have developed a novel manufacturing method of the grinding wheel that is possible to improve the uniformity in wheel structure. In this study, in order to compare the differences in grinding characteristics between the wheel produced by the novel method (uniform wheel) and the wheel produced by the conventional method ( conventional wheel), cylindrical grinding experiments for bearing steels have been carried out. The grinding ratio in grinding with the uniform wheel has increased by about 50% compared with the conventional wheel. The estimated tool life of the uniform wheel, based on the roughness of finished surface, has been about 1.9 times longer than that of the conventional wheel.
