一、概述砂带磨削是使高速运动着的砂带与工件接触进行磨削与抛光的一种工艺方法。它有生产率高、加工成本低、机床功率利用率高和经济效益显著等优点。砂带磨削的生产率比铣削高10倍,比砂轮磨削高4～10倍。砂带磨削在国外机械加工行业中已经得到了广泛的应用,国内一些重型机械加工行业也有所应用,但不很多。我厂自1979年开始进行砂带磨削工艺的试验和研究工 First, an overview Belt grinding is to make high-speed movement of the belt in contact with the workpiece grinding and polishing a process. It has the advantages of high productivity, low processing costs, high machine tool power utilization and significant economic benefits. Belt grinding productivity than milling 10 times higher than the wheel grinding high 4 to 10 times. Belt grinding in foreign machining industry has been widely used, some heavy machinery processing industry has also been applied, but not many. I plant since 1979 grinding belt grinding process of the pilot and research workers
