Sphering Mechanism for the Green Ceramic Balls Ground with the Two-wheels Grinding Technique

摘要

The machining of ceramic balls is one of the main difficulties of the manufacture process of ceramic ball bearings. This paper introduces a new grinding technique for green ceramic balls, the two-wheels grinding technique. The sphering mechanism for the green ceramic balls ground with the technique was analyzed in theory, and the influencing factors were studied by experiment. The experimental research presents that the spherical deviation of the ground green ceramic balls can be improved to 0.02mm.
