摘　　要：介绍了一种基于旋转磁性抛光液体的抛光技术。磁性抛光液体在磁力搅拌器的作用下产生旋转运动,利用外加强磁场作用增大磁性液体的粘度和剪切屈服应力,当加工工件放入磁性抛光液体中,磁性抛光液体与之相接触的工件表面发生磨削,从而达到对工件表面的光整加工。实验详细研究了磁性抛光液体抛光后工件的抛光区内表面粗糙度与抛光时间和位置之间的关系,实验结果表明:旋转磁性抛光液体抛光可以用于对工件进行超光滑加工,抛光时间越长,各处粗糙程度越接近,表面粗糙度越好,并且表面粗糙度比单独用研磨抛光膏的效果好。This paper presents a polishing technique that uses rotational magnetic polishing liquid, which can pro duce vortex motion under the action of a magnetic stirrer. The use of a strong external magnetic field increases its viscosity and shear yield stress when a workpiece is introduced into the magnetic polishing liquid. The magnetic polishing liquid contacts the workpiece surface grinding so as to achieve workpiece surface finishing. Experiments were carried out to study the relationship between the surface roughness of the workpiece, its polishing time and its polishing position. The experimental results show that the rotational magnetic polishing liquid can polish the super smooth surface and that the longer the polishing time and the closer the surface roughness at various locations, the better the surface roughness is, which is also better than that by using abrasive polishing alone.
