1) adopt the good SINUMERIK 802C numerical control unit of versatility, SINUMERIK 802C numerical control unit is compatible good to various universal frequency converters and AC servo machinery driving device, and antijamming capability is strong, and is cheap;
2) adopt the input/output signal of auxiliary reclay conversion PLC, auxiliary reclay can show whether the input/output signal of PLC is normal, facilitates tracing trouble;
3) adopt grease-box, and the input port of the alerting signal of grease-box access PLC;
4) adopt saddle controller, saddle controller is today's numerical control lathe control device commonly used, and the operation of energy cutter setting frame provides multiple protective;
5) turnning and milling shares, and switch board of the present invention adopts three AC servo motor, both can be set to lathe system, can be set to again the milling machine system, facilitates training and teaching and Technique Authentication;
6) adopt the double nut ball guide screw nat, cross slid platform major axis of the present invention is comprised of the double nut ball guide screw nat, can complete the task of the pretightning force of regulating ball guide screw nat;
7) the present invention selects micro-machine, and is safe and practical, and not high to power requirement;
8) the present invention can tear full dress entirely open, facilitates complete machine to debug.
