摘　　要：以45钢和不锈钢SUS304为研究对象,研究采用磁力研磨法对磁性和非磁性工件的微小沟槽表面的光整加工。通过理论分析,解析磁力研磨的加工机理。分别采用径向充磁和轴向充磁圆盘环形永磁铁作为磁极,结合Ansys磁场模拟分析与磁力研磨实验,探讨不同材质工件微小沟槽表面的光整加工工艺。实验结果表明:对于45钢微小沟槽表面的光整加工,不能选用圆盘环形轴向充磁磁极,应该选用圆盘环形径向充磁磁极,研磨加工后沟槽底面的表面质量要好于侧面;对于不锈钢SUS304微小沟槽表面的光整加工,选用圆盘环形轴向充磁磁极更适合,加工后底面和侧面都能获得较好的表面质量,加工效率较高。Takes 45# steel and stainless SUS304 as the research object, and studies the finishing machining of tiny groove surface of magnetic and non - magnetic material by magnetic abrasive finishing （MAF）. Through theoretical analysis, parsing the mechanism of magnetic abrasive finishing. Radial magnetization of per- manent magnets and axial magnetization of permanent magnets are used as magnetic pole respectively, and combines magnetic field simulation analysis in Ansys with magnetic grinding experiment to explore the finishing machining technology of tiny groove surface of different material workpieces. Not disk an- nular axial magnetization of magnetic pole but disk annular radial magnetization of magnetic pole should be chosen when finishing machining tiny groove surface of 45# steel, and after processing, bottom sur- face quality is better than the side. The disk annular axial magnetizing pole is more suitable when finish- ing machining tiny groove surface of stainless SUS304, and after processing, both the bottom surface and the side surface can obtain better surface quality, and machining efficiency is higher.
