CN102749258A Abrasion resistance testing machine for ceramic balls
The invention relates to an abrasion resistance testing machine for ceramic balls, comprising a working table; a ferrule base for mounting a standard ferrule is fixed on the working table; a fixed testing frame is mounted on the working table on a side of the ferrule base; a top of the fixed testing frame is hinged with a movable testing plate; the In recent years, Si 3 N 4 hybrid ceramic ball bearings, which are representative of hybrid ceramic ball bearings, have been gradually applied and popularised in the high-speed spindles of precision machine tools [3]. Their main advantage is the low density of ceramics, being 40 % below that of steel, which reduces the centrifugal loading Characteristics and mechanism of surface damage of hybrid ceramic ball

Establishment of material removal model for lapping ceramic balls
Lapping ceramic balls with variable-radius groove plate (VRGP) has obvious advantages in achieving good consistency of batch manufacturing of ceramic balls. The material removal model of a single ball was established based on Hertz contact theory. Then, combining the previous research works based on kinematic analysis and the Ball sizing, also known as ball broaching or Ballizing, is the process of forcing an oversize ball through the inside diameter of metal part. It will increase the inside diameter and greatly improve the surface texture of the part. Under ideal conditions, tolerances of one or two ten-thousandths of an inch and a mirror like surface can be achieved.Bal-tec Report On Ball Sizing
