一般的研磨是在两平面间或在两圆柱面之间放入研磨剂,使其相对运动。这些方法都只局限于母线是直线的零件,对于异形、复杂曲面零件的研磨就无能为力了。磁力研磨提供了一个解决办法,利用磁场吸引磁性研磨材料形成磁刷,使工件与磁极之间作相对运动(旋转或振动),就能实现曲面或异形零件的研磨。这种研磨方法具有很多优点:(一)磁性研磨可以调节,能获得较大的研磨力,因为调节电磁的电流是很方便简单的事;(二)可以多面同时研磨,效率高;(三)能容易地完成曲面和内、外表面的研磨,自动化程度较高;(四)研磨光洁度高,可用干式研磨,达到相当于 General grinding is in between the two planes or between two cylindrical surface into the abrasive, so that the relative movement. These methods are only limited to the linear parts of the bus, for shaped, complex surface grinding parts can not do anything. Magnetic grinding provides a solution that uses magnetic fields to attract magnetic abrasive materials to form magnetic brushes that allow the workpiece to move relative to the poles (rotating or vibrating) to achieve the grinding of curved or profiled parts. This grinding method has many advantages: (1) magnetic grinding can be adjusted to obtain larger grinding force, because the adjustment of electromagnetic current is very easy and simple; (2) multi-faceted grinding can be carried out with high efficiency; (3) Can easily finish the surface and the inner and outer surface of the grinding, high degree of automation; (D) grinding finish, available dry grinding, equivalent to
