改进碳化硅砂轮刃磨质量的基本途径是提高砂轮的自励性能。间断磨削法是通过砂轮开槽,间断与工件接触,来有效地提高砂轮的自励性能。高工件转速磨削对磨多刃刀具外圆有成效,实际上等于工件上开槽,间断与砂轮接触,因此也有利于提高砂轮的自励性能。这两种方法都是从工艺方面着手来提高砂轮的自励性。第一机械工业部磨具磨料研究所从砂轮本身着手,最近试验成功一种烧熔结合剂的碳化硅砂轮,具有良好的自励性能。同级硬度的 The basic way to improve the grinding quality of silicon carbide grinding wheel is to improve self-excitation performance of grinding wheel. Intermittent grinding method is through the wheel groove, intermittent contact with the workpiece, to effectively improve self-excitation performance of the wheel. High workpiece speed grinding on the grinding multi-blade tool cylindrical effect, in fact, equal to the workpiece slot, interrupted contact with the wheel, it is also conducive to improving self-excitation performance of the wheel. Both methods are from the craft to improve the self-motivation of the wheel. Abrasives Research Institute of the First Ministry of Machinery Industry proceed from the wheel itself, the recent successful trial of a sintered bonder silicon carbide wheel, with good self-excitation properties. The same level of hardness
