过去,我们是使用内圆磨床来加工内孔的。但由于内孔加工精度与表面光洁度要求提高了,所以采用老一套的办法就不能满足技术要求了。为了保证加工精度,我们利用原有内圆磨床,安装石墨砂轮进行磨削内孔的方法,解决了质量过不了关的困难。采用这种砂轮磨出来的内孔,其表面光洁度达▽▽▽▽11～▽▽▽▽12,精度达1～2级。砂轮制造比较简单,虽然应用这种方法磨内孔时,生产效率较低一些,但对于单件小批生产或试验是很适用的。尽管这一方法目前在提高生产效率以及扩大它的应用等方面,还存在着一
In the past, we used internal grinders to machine the bores. However, due to the inner hole machining accuracy and surface finish requirements increased, so the old set of methods can not meet the technical requirements. In order to ensure machining accuracy, we use the original internal grinder, the installation of graphite grinding wheel bore method to solve the quality of the difficulties. Using this grinding wheel out of the hole, the surface finish ▽ ▽ ▽ ▽ 11 ~ ▽ ▽ ▽ ▽ 12, accuracy of 1 to 2 levels. Grinding wheel manufacturing is relatively simple, although the application of this method of grinding the hole, the lower the production efficiency, but for a single small batch production or test is very applicable. Although this method is currently improving productivity and expanding its use, there is still a
