The principle of operation of principle of operation of the present invention and numerically controlled lathe is basic identical, does not just have mounting cutter in operation, can not produce true cutting.
Beneficial effect of the present invention is:
The present invention is exclusively used in the numerically-controlled machine of cultivating the student and debugs maintenance skills, and the one, can make the student grasp the principle of work of numerically-controlled machine and the effect of each components and parts through debuging of module one by one, lay the basis of diagnosing faults of numerical control machine; The 2nd, can be through tearing full dress entirely open, the basic skills of training student tool using and recognition electric diagram and machine debugging than high professional qualification; The 3rd, the components and parts of available inefficacy substitute original components and parts, the active design error failure, and training student diagnosis and the senior technical ability of fixing a breakdown, its main innovate point is embodied in:
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 auxiliary reclay to change the input/output signal of PLC, auxiliary reclay can show whether the input/output signal of PLC is normal, makes things convenient for tracing trouble;
3) adopt grease-box, and insert the input port of PLC to the alerting signal of grease-box;
4) adopt saddle controller, saddle controller is a today's numerical control lathe control device commonly used, can multiple protective be provided to the operation of knife rest;
5) turnning and milling is shared, and switch board of the present invention adopts three AC servo motors, both can be set to lathe system, can be set to the milling machine system again, makes things convenient for training and teaching and technical ability to identify;
6) adopt the double nut ball guide screw nat, cross slid platform major axis of the present invention is made up of the double nut ball guide screw nat, can accomplish the task of the pretightning force of regulating ball guide screw nat;
7) the present invention selects micro-machine for use, and is safe and practical, and not high to power requirement;
8) the present invention can tear full dress entirely open, makes things convenient for complete machine to debug.
