【摘要】 磁性研磨技术是近年来应用于精密表面光整加工的新方法、新工艺。本文阐述了烧结钕铁硼[Nd-Fe-B]永磁磁极头的设计思路;简要介绍了磁性研磨加工的装置及加工原理;分析了所开发的三种永磁磁极头对铜合金板、铝合金板和45#钢板进行磁性研磨加工的加工效果,验证了强永磁材料磁极头进行光整加工的可行性和可靠性。此项技术的开发及研究为三维自由曲面的磁性研磨加工奠定了理论基础,开创了一个新的技术途径。更多还原

【Abstract】 Magnetic lapping is a new surface finishing technique. When the magneto pole is used in the magnetic lapping, temperature in the processing area goes down, grinding ability of the magnetic grains rises, the volume of the magnetic appliance has been reduced. In the paper, the design idea for sintered Nd-Fe-B magneto pole has been described .The tests for the developed magneto poles have been done and the surface roughness of the finished workpieces have been improved very obviously. The development and the investigation of the technology in the paper, lays a theoretical foundation and develops a new method for finishing the curved surfaces automatically under the numerical control.更多还原
