NC machine tool solves the problem of complex, precise, small batch and multi-variety parts. It is a flexible, high-efficiency automatic machine tool, represents the development direction of modern machine tool control technology, and is a typical mechatronics Chemical products.    

In order to improve the performance of CNC machine tools, the feeding application scheme of CNC machine tools supporting the Elias AC servo system has the following characteristics:    
(1) High precision: It guarantees the quality and efficiency of parts processing, and ensures the positioning accuracy and processing accuracy of CNC machine tools. Achieved high positioning accuracy, such as 5µm, 1µm, etc. in position control; while in speed control, high speed regulation accuracy and strong anti-load disturbance ability, that is, static and dynamic speed drop May be small.    
(2) Fast response: In order to ensure the accuracy of contour cutting shape and surface roughness, in addition to ensuring high positioning accuracy, it also ensures that the system has good fast response characteristics, that is, the response of the tracking command signal is fast and the position tracking error is guaranteed. (Position tracking accuracy) should be small.    
3 (3) Wide speed adjustment range: For CNC machine tools, the feed servo system ensures that it can work normally in the wide speed adjustment range of 0 ～ 24m / min.    
(4) Low-speed and large-torque: According to the characteristics of the machine tool, most of the heavy-duty cutting at low speed, the feed servo system ensures a large torque output.
