许多机件的摩擦副表面,特别是圆柱面,例如轴与轴套,阀体与阀芯,活塞与油缸,柱塞与缸体孔等,不少用手工研磨进行终加工。随着精密磨削的广泛应用,这些表面的光度(▽8～▽11)和精度都能通过精磨达到。为提高生产效率,降低劳动强度,生产中强烈要求用精磨代替手工研磨。但需研究以磨代研对摩擦副耐磨性的影响。日本摩擦学家佐藤健児认为,磨削加工面有变质层,其耐磨性不但比珩磨、研磨面
Many parts of the friction surface, especially the cylindrical surface, such as the shaft and sleeve, the valve body and the valve core, piston and cylinder, plunger and cylinder bore, many manual grinding for finishing. With the wide application of precision grinding, the luminosity (▽ 8 ~ ▽ 11) and the precision of these surfaces can be achieved by precision grinding. In order to improve the production efficiency and reduce the labor intensity, the production strongly requires the use of fine grinding instead of manual grinding. But the need to study the wear on behalf of the friction pair wear resistance. Japanese tribologists Kenji Sato that the grinding surface has a degenerative layer, not only its wear resistance than honing, grinding surface
