零件的后锪孔、锪面加工，由于受零件结构限制难度较大。目前在此种零件加工时大都采用带方孔的刀杆，先将刀杆插入孔内，然后将事先刃磨好的刀块装入刀杆上进行加工。这种加工方法不仅工艺较为落后，而且生产效率及零件加工质量都比较低，很难满足生产要求。为此，笔者根据当 After the hole, face, face processing, due to part structure constraints more difficult. Currently in the processing of such parts are mostly used with a square hole arbor, first arbor into the hole, and then a good sharpener before the knife into the bar for processing. This processing method is not only backward technology, and production efficiency and quality of parts are relatively low, it is difficult to meet production requirements. To this end, the author based on when
