Abstract:The cutting technology of blind hole sleeve core rod for main shaft of largescale equipment such as steam turbine is studied.Through the research of cutting working principle，the cutting knife mechanism and blade structure shape are determined，and an automatic cutting knife for blind hole bar is designed.The cutting process and motion trajectory are analyzed，and the appropriate variable parameter cutting process is formulated.The test proves that the cutting knife can cut the mandrel efficiently and automatically.
