喷注器盘是液体发动机的一个关键零件,材料为不锈钢,在这个零件上需要加工许多成对相交的小孔,如图1为某型号发动机的喷注器盘,在不同半径的园周上就有直径为小0.9～2.6mm近千对小孔,每对孔轴线不相交度0.05 mm,交汇点高度差H　 0.1mm。在不锈钢零件上钻小孔是十分困难的,现在 The injector plate is a key part of the liquid engine and is made of stainless steel. Many pairs of intersecting holes need to be machined on this part. As shown in Figure 1, an injector plate of a certain type of engine is mounted on a circle of different radius There is a small diameter of 0.9 ~ 2.6mm nearly thousand pairs of holes, the axis of each pair of non-intersection of 0.05 mm, intersection height difference H 0.1mm. It is very difficult to drill holes in stainless steel parts right now
