Based on the requirements of spinneret micro-hole machining,the automatic spinneret micro-hole machining scheme is designed.Firstly,the hardware structure and control system of digitally controlled precision machining machine tool are designed.In order to solve the three problems of delayed tool wear compensation,easy breaking of flat drill and difficult row of blind drill chips,Three functional design schemes of tool wear compensation,online monitoring of tool damage and blind hole chip removal are put forward,and the application optimization of micro-hole drilling technology is carried out from four aspects:determination of bottom hole process parameters,optimization of cutting parameters,selection of flat drilling materials and comparison of hole bottom processing,and optimization of flat drilling processing problems,aim-ing at realizing the goal of automatic micro-hole machining of spinneret and improving the quality and effi-ciency of micro-hole machining of spinneret.
