本文介绍了一种用于钢轨表面除蚀的新型磨光机，该机把砂带磨削原理、ＰＬＣ与液压控制融为一体，成功地应用于钢轨电极接触面磨光机上，经三年多的运行考核，取得了十分可观的效益。
This paper introduces a new type of grinding machine for removing corrosion on the rail surface. The machine combines the principle of abrasive belt grinding, PLC and hydraulic control into one and is successfully applied to rail electrode contact surface polisher. After more than three years The operation of the assessment, made a very substantial benefit.
