A countrys level of CNC machine tool industry has become of an important sign of the countrys manufacturing industry to measure the level of industrial modernization and the countrys comprehensive competitiveness , directly bearing on national economic construction and national defense and national security and strategic position. CNC lathe as a key component of the research is of important significance. font color=#9a9a9a/font br / Micro-CNC lathe of CK0620 is a multi-functional desktop lathe. It is simple and practical, user-friendly, cost-effective, and other characteristics, to achieve a straight line, taper, arc, thread and other parts of the complex processing, and as a teaching machine. From the research, we can know the basic principle and the basic structure of the CNC lathe, laying a good foundation for future work.br / This main content of the paper is studying the spindle system, the feed drive system, the NC system. The machine spindle motor drive system uses frequency reducer combination with the box, feeding system using stepper motor-driven ball screw and nut combination of transmission, making the machine structure is simple, easy to use, high precision machining and other features.br / br /
