This paper introduces the design of CNC hobbing machine with large-modulus and fewer teeth to fill the blank of the market.The structure of the CNC hobbing machine is designed with modular design method,and the layout of open vertical machine tool with large vertical column and fixed platform is adopted.In structure,the bed is strengthened and it s heat-balance structure is designed,the spindle system with larger tool installation space uses the structure to coordinate gap,improve the speed of the workbench.In addition,the suitable and sufficient spindle motor is chosen by calculation,so that the machine can cut the gear with large-modulus and fewer teeth in high speed and short time.The NC machine has developed the function of automatic programming software on the basis of the universal numerical control system.Input the corresponding gear parameters,tool parameters,installation parameters and process parameters through friendly man-machine interface,the software can automatically generate the machining code of machine tool recognition,so that the efficiency of hobbing programming can be greatly improved.
