在使用MZ7650双端面磨床时,我们对接触工件的非软磨端面部分采用铸铁盘代替砂轮的措施,实现套圈软磨端面时的单端面磨削,见右图。这种磨削方法的缺点是:(1)端面连续进行磨削,砂轮与工件长时间接触,散热是主要问题。(2)生产效率高,每个工件被磨时间极短,磨削后工件表面粗糙度大,砂轮磨损快,工作尺寸难以控制。为了解决以上问题,必须合理地选择砂轮。
When using the MZ7650 double end face grinder, we use a cast iron disc instead of a grinding wheel to contact the non-soft end face of the workpiece to achieve single end face grinding when the ferrule is soft-ground. See the picture on the right. Disadvantages of this grinding method are: (1) End face continuous grinding, grinding wheel and the workpiece for a long time contact, heat is the main problem. (2) high production efficiency, each workpiece is very short grinding time, after grinding the workpiece surface roughness, grinding wheel wear fast, difficult to control the size of the work. In order to solve the above problems, we must choose a reasonable wheel.
