本文叙述了单磨粒磨损试验研究的结果。在飞铣状态下进行磨粒试验,磨粒装在金属盘的周边上,代替砂轮工作。实验结果发现,磨损率与切削长度成正比,并随工件硬度、砂轮速度和未变形切削厚度的增加而增加。对用较硬磨粒观察到的较大磨损率提出了有可能性的解释。实践表明,高速磨削能获得较高的效率。

This article describes the results of a single abrasive wear test. Grinding test in the flying state, abrasive mounted on the periphery of the metal plate, instead of grinding wheel work. The experimental results show that the wear rate and cutting length is proportional to, and with the workpiece hardness, grinding wheel speed and increase the thickness of the non-deformation increases. A possible explanation for the higher wear rates observed with hardgrinding particles. Practice shows that high-speed grinding can get higher efficiency.
