The numerically-controlled machine tool master drive system is uses for to realize the engine bed main movement transmission system. Including electric motor, transmission system and spindle unit. This article through designs to XK5025 numerical control milling machine master drive systems various aspects, achieves the low production cost, the simplified organization, to realize the optimization. Uses the frequency conversion electrical machinery and the first-level machinery velocity modulation achieves the velocity modulation and the transmission power request; With step-by-steps the motor-driven main axle vertical motion to achieve the Z traveling schedule the request; The numerical control installment uses 51 monolithic integrated circuits to realize to an electrical machinery more precise control and realizes the machinery velocity modulation automatic control.
