摘要：The ball screw and linear guide are important transmission components of a feed system, and their structure directly influences the static and dynamic characteristics of a machine tool. This study used finite element analysis to analyze the static and dynamic characteristics of the spinning machine with different structural designs. Results showed that the feed system is the key functional component that influences the static and dynamic characteristics of the entire machine. A design method is proposed for the structural optimization of the spinning machine based on the structure of the ball screw and the linear guide. Four three-roller models and five counter-roller models are established. A single-factor analysis method is adopted for the contrastive analysis of the static and dynamic characteristics. Finally, the structure of computer numerical control spinning machine with the optimal feed system structure is optimized. The analysis indicates that the reasonable optimization of the structure of the b...
