钢球精研过程是敷砂和嵌砂两种研磨类型的复合,以半干研为主要特征。钢球表面金属的微细脱落属于磨料磨损;精研板沟槽表面的麻坑则属于表面疲劳磨损。提高板沟与钢球的密合精度可以延长板沟的疲劳寿命和提高钢球的表面质量。附图1幅,表2个。
Ball lapping process is sand and sand filling sand grinding two types of composite to semi-dry research as the main feature. The fine metal off the surface of the ball belongs to abrasion of the abrasion; the pit on the surface of the groove of the lapping plate belongs to the surface fatigue wear. Raise the tightness of the groove and steel ball can extend the fatigue life of the groove and improve the surface quality of the steel ball. Figure 1, Table 2.
