The current precision axis process parameters are mainly based on the production process and determined by the process database. The five-axis precision parts machining database is generated by production experiments based on the characteristics of current production equipment and other standard conditions. In specific production, the process parameters cannot be applied to the production due to minor changes in materials, production equipment, personnel, processes and environment.
Precision CNC machining of precision shafts are mainly made of 3Cr13, which is generally quenched and tempered to a strength of 500-700 HV. The key optical shaft production process is: cable disconnection → heat treatment → tempering → straightening → end grinding → rolling → bore fine grinding → medium rolling → bore fine polishing → fine rolling → cleaning → demagnetization → appearance inspection → packaging. General shaped precision shaft processing production process is: CNC cutting → heat treatment → tempering → rough rolling → OD fine grinding → OD semi-precision polishing → medium rolling → OD fine grinding → fine rolling → ultrasonic cleaning → demagnetization → appearance inspection → packaging.
