我厂一台 M1432型普通外圆磨床,系上海机床厂1972年制造同年投产使用至今。近期来出现当工作台纵向行程到100毫米/分时就产生严重的爬行现象,操作者无法打磨砂轮,精度和光洁度都达不到要求。为了解决这一矛盾,经认真讨论和研究,我们认为首先必须要解决磨床的低速爬行问题。因为在其他条件一定的情况下,工件表面光洁度,是随着修整时工作 I plant a M1432-type general cylindrical grinding machine, the Department of Shanghai Machine Tool Plant in 1972 the same year put into operation manufactured use so far. In the near future, when the longitudinal stroke of the workbench reaches 100 mm / min, serious crawling occurs. The operator can not polish the grinding wheel, and the accuracy and the finish are not met. In order to solve this contradiction, after careful discussion and research, we think we must first solve the low-speed crawling grinder problem. Because of other conditions under certain circumstances, the workpiece surface finish, is working with trimming
