This paper summarizes the basic composition and working principle of CNC machine tool servo system. As the core component of CNC machine tool, servo system is mainly composed of servo motor, drive controller, position sensor and other parts, by precisely controlling the speed and position of the motor, to achieve the precise movement of the machine tool. In this paper, the function of each component of servo system and the interaction between each other are analyzed in detail, which lays a foundation for the subsequent performance improvement strategy research. This paper analyzes the main factors that affect the performance of CNC machine tool servo system. These factors include the dynamic response characteristics of the servo motor, the control strategy of the drive controller, the accuracy and stability of the position sensor, etc. In view of these factors, this paper has carried on the in-depth discussion, and pointed out the influence mode and degree of each on the servo system performance. This paper puts forward the specific strategy of improving the performance of CNC machine tool servo system. In the servo motor, the dynamic response ability of the servo system is improved by optimizing the motor design and improving the motor speed and torque. In the driving controller, advanced control algorithms and strategies are adopted, such as fuzzy control, neural network control, etc., to improve the control accuracy and stability. In terms of position sensors, high-precision and high-stability sensors are selected to ensure the accuracy of position detection. In addition, this paper also emphasizes the cooperative optimization among all parts of the servo system and the improvement of the overall performance, and puts forward the comprehensive optimization strategy. This paper deeply discusses the performance improvement strategy of CNC machine tool servo system, and comprehensively analyzes the working principle, performance influencing factors and improvement strategy of servo system. By optimizing the performance of key components such as servo motors, drive controllers and position sensors, adopting advanced control algorithms and strategies, and strengthening the collaborative optimization between various parts, the overall performance of the CNC machine tool servo system can be significantly improved, and the machining accuracy, efficiency and stability of the machine tool can be improved.
