为了完善环带抛光技术并指导加工，根据Preston方程建立了材料去除量的理论模型。考虑环带抛光技术中的影响因素，如抛光盘与工件之间的转速比、偏心距及压强分布等参数，建立了材料去除量与各影响因素之间相互关系的数学模型。理论分析和实验结果显示，转速比、偏心距和压强分布对磨削量均有影响，材料的去除效率随转速比和偏心距增加而增大，转速比越接近于1，磨削越均匀；工件露边时，工件露出部分材料的去除效率急剧下降。实验结果表明，通过对该理论模型中相关技术参数的研究来完善环带抛光技术，有效地提高了抛光的效率及稳定性。

In order to improve the zone polishing technology, a material removal theoretical model of zone polishing technology is founded based on the Preston equation. In consideration of all influencing factors, such as rotating speed ratio, eccentric distance, pressure distribution between polishing laps and workpieces, the mathematical model about the relationship between the material removals and the influencing factors is established. The theoretical analysis and experiment results indicate that the rotating speed ratio, eccentric distance and pressure distribution all have effects on the material removals. The material removal efficiency is increased as the increases of rotating speed ratio and eccentric distance. When the rotating speed ratio is near to 1, the removal distribution is more uniform. The material removal efficiency of edge is quickly reduced as the edge of workpiece holds out of the polishing lap. These results show that the zone polishing technology is improved through researching the technological parameters of the theoretical model, and the polishing efficiency and stability are increased.
