利用立式钻床通过铸铁研磨盘对小型平面及圆柱进行研磨,能够获得▽▽▽▽10以上的表面光洁度,精度也能控制在0.005毫米以内,是一种经济简便的机械研磨方法。根据实验证明,对油泵的叶片、精密轴承的滚针等进行研磨,都得到良好的效果。 Using a vertical drilling machine to grind a small flat surface and a column with a cast iron grinding disc, it is possible to obtain a surface finish of ▽ ▽ ▽ ▽ 10 or more and the accuracy can be controlled within 0.005 mm. This is a economical and simple mechanical grinding method. According to the experiment proved that the pump blades, precision bearings, such as needle roller grinding, have been good results.
