In order to improve the finishing efficiency of the Magnetic Abrasive Finishing process, we proposed a new MAF process with renewable abrasive particles using compound magnetic finishing fluid circulatory system in this paper. This new finishing process has a circulating system that uses a conveyor belt to renew the mixed abrasive particles. This not only maintains the stability of the finishing but also ensures that the processing does not need to be interrupted. In this study, we investigated the magnetic field distribution, finishing force, and finishing behavior of the processing area. Furthermore, we designed experimental device to finish the sus304 stainless steel plate, to verify the feasibility of this process and understand its characteristics through processing experiments. Moreover, the influence of important process parameters, including magnetic particles, abrasive particles, conveyor belt line speed and working gap, on the surface quality of the workpiece is studied through the experiment. The experimental results indicate that the present process can achieve stable processing of the material surface without interruption, and the surface roughness of the sus304 stainless steel plate has been improved from 273 nm to 23 nm through this process.

为了提高磁性磨料精加工工艺的精加工效率，本文提出了一种使用复合磁性精加工液循环系统的可再生磨粒的新型MAF工艺。这种新的精加工工艺有一个循环系统，该系统使用传送带更新混合磨料颗粒。这样既保持了精加工的稳定性，又保证了加工过程不需要中断。在这项研究中，我们研究了加工区域的磁场分布、精加工力和精加工行为。此外，我们设计了实验装置来完成sus304不锈钢板，通过加工实验验证该工艺的可行性并了解其特性。此外，重要工艺参数的影响，通过实验研究了包括磁性颗粒、磨料颗粒、输送带线速度和工作间隙等对工件表面质量的影响。实验结果表明，本工艺可以实现对材料表面的稳定无中断加工，通过该工艺，sus304不锈钢板的表面粗糙度由273nm提高到23nm。
