After actual processing, due to the influence of factors such as machine precision and skill of an operator, deviation exists between the processing datum and the theoretical value and the assembling precision is poor. The assembly precision problem is mainly reflected in the phenomenon that the errors of a guide sliding surface and a lapping surface of a lapping part are large, the guide sliding surface is usually opened or interfered, and the 3D surfaces of a male die and a movable male die are not lapped smoothly or are not smoothly after repeated assembly. Resulting in a large amount of numerical control reworking processing and large internal consumption.
