ABSTRACT
The design of the development and application of NC machine tools was introduced, and the structure characteristics of the NC machine tools are summarized. Main design is CK6140 NC machine tool main driving system, its main contents include: speed figure drawing up, the design and calculation of change gear, belt transmission design and calculation, the selection of the encoder and the installation and so on. The design results show that the machine has simple structure, easy maintenance and cost-effective.
CK6140 CNC lathe headstock by the installation in the precision bearing of hollow spindle and a series of change gear. CNC lathe spindle can get any speed within the speed range, in order to meet different processing requirements of cutting.
Key words: CNC lathe; headstock ; main driving system
