为了提高有色金属的磨削生产率,苏联某厂把有色金属的零件放在外圆磨床、平面磨床和无心磨床上进行磨削。在选用砂轮时,应考虑到磨粒的材料、粒度、粘结剂及硬度等各方面条件。磨料的选择是根据被加工的有色金属或有色金鼠合金的性质来决定;而粒度是根据被磨表面的光洁度来决定。其中以黑色碳化硅(ΚЧ)磨料或标 In order to improve the non-ferrous metal grinding productivity, a factory in the Soviet Union places non-ferrous metal parts on cylindrical grinding machines, surface grinding machines and centerless grinding machines for grinding. In the selection of grinding wheel, should take into account the abrasive material, particle size, binder and hardness and other conditions. The choice of abrasive is based on the nature of the non-ferrous or non-ferrous alloy that is being processed; the grain size is determined by the finish of the surface to be ground. Including black silicon carbide (ΚЧ) abrasive or standard
