摘　　要：基于CBN油石的超硬特性、良好自锐性以及CBN油石超精的丝路、峰线豁口,简要分析了采用CBN油石超精对沟道波纹度和残余压应力等表面质量指标的影响,深入分析了轴承自润滑能力提高的机理以及对提高轴承寿命的影响。Based on the ultra-hard characteristics and good self-sharpening of CBN oilstone, as well as the ultra-fine wiredrawing striation and peak line gap produced by it, the effect of CBN superfinishing on surface quality indexes such as groove waviness and residual compressive stress is briefly analyzed, and the mechanism of improving the self-lubricating ability and the effect on improving the bearing life are analyzed.
