The surface of the part is required to be higher, or the hardness of the material is relatively lower, so that the surface is easily scratched by metal scraps when hole machining is carried out, and the surface quality of the part is affected.
At present, in order to ensure that the quality of the peripheral surface of a hole is not affected when the hole is machined by a part, common hole machining processes are as follows: firstly, a certain margin is reserved on the surface of a part in the previous working procedure of the hole machining working procedure, then the surface of the part is subjected to hole turning, chamfering and other processing, and then the part is returned to the previous working procedure for finish machining. However, there is a problem that since there is a machining allowance on the surface of the part during the hole machining, the chamfer of the hole machining also includes an allowance, and meanwhile, the allowance left on the surface of each part machining hole is actually different, so that the size of the chamfer allowance is not easy to accurately control, and the consistency of the chamfer of the orifice after the finish machining of the surface of the return path is poor. In addition, in the process of returning to the previous working procedure for finish machining after hole machining, the surface states of the parts are similar, so that the quality hidden trouble of finish machining leakage exists. Meanwhile, the process returns to finish machining, so that the number of parts is increased by one turnover and one clamping, and the machining efficiency of the parts is reduced.
Therefore, the improvement of the part hole processing technology is urgently needed, the finish processing technology of the part returning to the last pass is eliminated, and the problems are thoroughly eliminated.
