By adopting the spot facing machining device provided by the invention, in the machining of the integral blade disc sewage discharge hole of a certain machine, the problems that a forming spot facing cutter cannot be used on an electric tool or a pneumatic tool due to interference and the round of the orifice of the sewage discharge hole can only be manually polished and repaired by workers are effectively solved. The original workload of one shift can be finished in less than half an hour, the labor intensity of workers is reduced, and the work efficiency is improved by 15 times. The dimensional consistency after processing is also very good, and the product quality is effectively controlled and improved.
In addition, in the manufacture of aircraft engines, many parts have complex structures. Such interference phenomenon exists in the processing of many adherent holes similar to the above-mentioned blowoff hole, has increased the processing degree of difficulty, greatly influences machining efficiency and product quality. This counter boring processingequipment can effectively solve this type of problem, can obtain extensive application in the actual production.
