通过多次试验证明:在研磨过程中磨料生产率降低的主要原因是磨粒的碎裂,使能够产生研磨作用的大磨粒数量减少,而碎裂后的小磨粒容易被切屑堵塞,以致不能起切削作用。而磨粒碎裂前切削尖棱并未显著钝化,所以切削能力并未丧失,只是粒度变小些。试验还证明磨料粒度过大也使生产率 Through many tests, it is proved that the main reason for the decrease of the abrasive productivity during the grinding process is that the abrasive particles are fragmented so that the amount of the large abrasive particles capable of producing the grinding effect is reduced, and the fractured small abrasive particles are easily blocked by the chips so as not to From the cutting effect. However, the cutting edges before grinding debris did not passivate significantly, so the cutting ability was not lost, but the grain size became smaller. Experiments also show that too large abrasive particle size also leads to productivity
