摘要：利用雾化法制备的磁性磨料, 通过自行研制的微型数控研磨机床, 以S136模具钢为工件, 进行磁力光整加工实验, 考查主轴转速、磁性磨料粒度、磁场强度等因素对磁力光整加工中工件的表面粗糙度的影响。结果表明, 主轴转速为900 r/min, 磁性磨料粒径在104~150μm, 磁场强度为0.9 T时, 磁力光整加工中工件的表面质量最佳。

Abstract：In order to experimentally research magnetic abrasive finishing with magnetic abrasive by gas atomization method, S136 die steel was finished on self-designed micro numerical control finishing machine. Experiments were carried out to research the effect of various factors such as spindle speed, particle size of magnetic abrasive and magnetic field intensity on workpiece surface roughness. The results indicate that the best parameters are 900 r/min of spindle speed, grain size range from 104 to 150 μm of magnetic abrasive and 0.9 T of magnetic field intensity.
