无心磨削是外圆加工时常用的方法,它具有效率高,上下料方便,不需定心,磨削余量小,两端不需打中心孔等特点,因此,在大批量生产中被广泛采用。在加工中,经常出现的非正常现象有:火花不均匀、工件跳动、工件圆周滑动。相应地会出现产品的各种缺陷,如圆周误差,直线度误差,表面粗糙度值高等。往往生产单位出现这个问题之 Centerless grinding is a commonly used method of machining in the outer circle. It has the characteristics of high efficiency, convenient loading and unloading, no centering, small grinding allowance and no need to hit center hole at both ends. Therefore, in mass production, broadly used. In the processing, often appear abnormal phenomenon: non-uniform sparks, the workpiece beating, the workpiece sliding around. There will be a variety of product defects, such as circumferential error, straightness error, surface roughness value higher. Often the production unit appears this problem
