摘要：

A new method of finishing advanced ceramics, namely, magnetic fluid grinding with a float, has been developed especially for Si3N4 balls. The removal mechanism in this process and the optimum grinding conditions have been studied in the last seven years. In this paper, the results from the published papers are surveyed and summarized from the viewpoints of removal rate, surface roughness and sphericity of balls. From this review, it was found that magnetic fluid grinding can be applied to the rough finishing process at high speed. However, ifa sphericity smaller than 0.1 mu m is required, some new ideas are necessary.
