NC innovation can meet production needs with short transformation period. Take the CA6140 lathe as an example, in this paper to process numerical control innovation design of mon lathes. The main research contents are as follows: Analysis the structure, ponent and function of the mon lathes, and identify the numerical control innovation scheme of mon lathes and do economy demonstration. According to the mon lathe processing ability, design partial reconstruction of the lathe spindle box, and give brief illustration. According to the mechanical and electrical design principle, and the machine feeding system requirement, making calculation of cutting force, and choose appropriate ball screw and assembly design. Design choice ball screw supporting mode and to choose corresponding bearings, stepping motor. Making selection of design automatic rotary tool post and corresponding checking calculate. According to the properties and transformation of precision index to select suitable numerical control device system. Give installation and debugging method of mon lathes numerical control innovation.
