This study propose a new plane magnetic abrasive finishing process to improve the surface accuracy. In conventional plane magnetic abrasive finishing process, the magnetic particles are easy to cohesion, which hampers the realization of ultra-precision processing. Therefore, a new plane magnetic abrasive finishing process by the use of varying magnetic field has been proposed in this paper. Through the design of a new set of experimental device, the up and down movements are generated in the varying magnetic field by magnetic particles, thereby processing the workpieces. The movement changes of magnetic particles in water-soluble grinding fluid and oily grinding fluid have been observed and the finishing force has been measured. Further, C2801 brass plate surface has been polished by using the new plane magnetic abrasive finishing process, and the feasibility of this new method has been proved by the experimental results. The workpiece surface quality can be improved by this method.
