把砂轮分成粗加工区和精细加工区,使用电镀结合CBN砂轮,能够明显提高内孔切断磨削过程的放率。用内孔切断磨削的办法对已经淬火的盘类工件孔进行最终加工,是一种经济灵活的磨削方法。这种方法能够通过一次精磨,加工出所要求的工件表面。与其他内孔磨削方法相比,由于砂轮厚度小,在单位时间切削时,摩擦力和工件温度都很低。通过把砂 The wheel is divided into rough machining area and fine processing area, the use of electroplating combined with CBN wheel, can significantly improve the rate of cut-off grinding process within the hole. With the hole cut grinding method has been quenched disk type workpiece hole for final processing, is an economical and flexible grinding method. This method is able to produce the desired surface of the workpiece by a single pass. Compared with other bore grinding methods, due to the small thickness of the grinding wheel, cutting unit time, friction and workpiece temperature are low. By putting the sand
