Thermal Characteristics Analysis of Feed Axis Ball Screw Pair Based on Thermal Network Method

The ball screw pair is a key transmission component in the feed system of modern CNC machine tools. Its performance directly affects the accuracy and stability of the system. Due to working conditions such as high load and high speed, the ball screw pair will generate a lot of heat during operation. This causes the temperature to rise, which in turn affects its lubrication state, wear and the dynamic performance of the entire system. Therefore, studying the thermal characteristics of the ball screw pair is of great significance to improving its working performance and extending its service life.
