在普通外圆磨床上加工▽10～▽12的轴类工件时,一般都是采用经过粗、精磨后,再进行研磨的方法。这样,不仅效率低,而且质量也不稳定。为了提高生产效率和加工质量,我厂采用了精密磨削方法(将过去用油石精修砂轮,改用金刚石精修砂轮),光洁度可提高到▽11～▽12。 In the ordinary cylindrical grinder machining ▽ 10 ~ ▽ 12 of the shaft workpiece, are generally used after coarse, fine grinding, and then grinding method. In this way, not only inefficient, but also the quality is not stable. In order to improve the production efficiency and processing quality, our factory adopts the precision grinding method (using pasting stone with grinding stone and using diamond finishing grinding wheel), the finish can be improved to ▽ 11 ~ ▽ 12.
