A novel method was proposed to improve surface quality of bearing friction pair with nanometer grind technology. Using special nanometer material, mechanical grind and chemical abrasion were implemented at the same time. The grinding mechanism, characteristics of each grinding materials, and processing technology of new method were accounted in detail. With quantity of experiments on different kinds of bearings, measuring and analyzing surface morphology of friction pair, it is found that the chemical grinding method could effectively improve bearing＇ s surface morphology, reduce running vibration and noise, and increase hearing＇s quality.
