砂带是国外六、七十年代蓬勃发展起来的一种新型涂附磨具。它具有磨削效率高、抛光作用强、机床能量利用率高、磨削温度低等主要特点,在许多工业部门已获得广泛应用。但由于砂带只有一层磨料,为保持切削能力,一般不进行修整,再加上受力变形等其它一些原因,与砂轮相比,其磨削精度较低。目 Belt is a new type of coated abrasive developed vigorously in foreign countries in the sixties and seventies. It has the main features of high grinding efficiency, strong polishing effect, high energy efficiency of the machine tool and low grinding temperature. It has been widely used in many industrial sectors. However, as the abrasive belt has only one layer of abrasive material, in order to maintain the cutting ability, it is generally not trimmed, coupled with mechanical deformation and other reasons, compared with the grinding wheel, the grinding accuracy is low.
