磁力光整加工铝镁合金永磁极研究
Research on Magnetic Abrasive Finishing Processes of Aluminum-magnesium Alloy Permanent Magnet Poles
摘要
Abstract
Based on the XK7136C CNC milling machine with spindle modification,the AZ31 series magnesium alloy and 7075-T651 aluminum alloy were used as the research objects. The theoretical calculation and magnetic field simulation were used to design the strong permanent magnet material for the machining of aluminum-magnesium alloy structural material magnetic poles, and the use of atomized fast-rolling spherical abrasive particles was tested to verify the feasibility of the finishing method and spherical abrasive performance."Tian word slot"and"Mi word slot"magnetic poles were used to test the two kinds of materials respectively. The experimental results show that two kinds of end slotting methods may prevent the local accumulations of abrasives,ensure the abrasive flowability,and increase the magnetic flux density and improve the grinding efficiency. The surface roughness of the two poles are as 0.126 μm and 0.148 μm respectively. The end faces with a stronger magnetic flux density of the" Tian word slot"magnetic pole are more efficient in the prophase polishing processes.关键词
