Study on Plan Magnetic Abrasive Finishing - Discussion on Processing Methods for Improving Flatness

Abstract:

Magnetic abrasive finishing (MAF) is a precision surface polishing method. At present, most studies on planar MAF are focused on improving the surface roughness accuracy and the uniformity of roughness. In practical applications, the initial surface of the work piece is not only a rough surface, but also a flat surface without a uniform height. While the traditional processing method improves the surface roughness accuracy, the original surface is basically unchanged. In this paper, a processing method is studied. According to the uneven distribution of magnetic brushes, the reasonable distribution of processing speed and processing time can finally achieve the purpose of improving the surface flatness. At the same time, this paper analyzes the non-uniform characteristics of the magnetic pole and the magnetic brush itself, and verifies the effectiveness of the processing method through experiments.
