Shaft part scraping and cutting system and scraping process

The invention relates to a shaft part scraping and cutting system and technology. The cutting system comprises a machine tool base, a backrest plate, a shaft radial supporting frame, a shaft clamping tip, a tool rest driving motor, a tool rest and a scraping tool. Shaft clamping tips are installed at the two ends of a machine tool base respectively, a backrest plate is installed on the outer side of the machine tool base, a plurality of shaft radial supporting frames are sequentially installed on the side, facing a machined shaft, of the backrest plate, a tool rest driving motor and a tool rest are installed on the inner side of the machine tool base, and a scraping tool is installed on the tool rest. According to the scraping technology, no cuttings or a small amount of cuttings are generated in the cutting process, and the rear tool face of the scraping tool slides on the surface of a pressing shaft and the surface of a torsion shaft to generate pressure stress.
