据日本报导,磁力磨削法不仅用于去毛刺,而且能对平面、外圆、内孔、球面、自由曲面进行加工。经磁力磨削法加工的工件表面粗糙度,已可达到R_(max)0.1μm。以磁力磨削外圆为例.如图1所示,工件装夹在磁极N-S中间,在工件与磁极之间充满着磁性磨粒,当工件是磁性体时,磁性磨粒就会沿磁力线排列成刷子状,形成磁力磨削刷,对工件表面产生压力P_x。当工件在磁极中间旋转时,这时磨粒就会受到切向磨削阻力P_y的作用,从而产生磨削作用。为了加强磨削作用,工件还作轴向低频振动。磁力磨削过程中,磨粒还受到因磁埸分布不均而产生的磁力F_m的作用,从而防止了磨粒向磨削区外流出,使磁性磨粒
According to reports in Japan, magnetic grinding method not only for deburring, but also on the plane, cylindrical, bore, spherical, free-form surface processing. The surface roughness of the workpiece machined by magnetic grinding method can reach R max 0.1μm. Magnetic grinding cylindrical as an example. As shown in Figure 1, the workpiece is mounted in the middle of the NS pole, between the workpiece and the pole filled with magnetic abrasive particles, when the workpiece is a magnetic body, the magnetic abrasive particles along the magnetic line Into a brush-like, forming a magnetic grinding brush, the pressure on the workpiece surface P_x. When the workpiece in the middle of the pole rotation, then the abrasive will be tangential grinding resistance P_y role, resulting in grinding effect. In order to enhance the grinding effect, the workpiece also for axial low-frequency vibration. In the course of magnetic force grinding, the abrasive particles are also affected by the magnetic force F_m generated due to the uneven distribution of the magnetic ridges, thereby preventing the abrasive particles from flowing out of the grinding zone, so that the magnetic abrasive particles
