Meanwhile, the particularity of deep hole processing also forms a difficult problem in the processing process: difficult chip removal, difficult cooling and lubrication, low rigidity of a tool system and poor self-guidance of the cutter. The problems are puzzled in the deep hole machining industry for a long time, the process range, the machining efficiency and the machining quality of deep hole machining are greatly limited, and the capacity of expanding the deep hole machining technology to other fields is also limited.
