With the demand for high-speed and high-precision development of CNC machine tools, ball screw, as one of the main feed functional components of CNC machine tools, is particularly important for its selection and installation to ensure the transmission accuracy of the machine tool; So, what are the requirements of CNC machine tools for ball screws?

1. Accuracy retention: As an important transmission component of CNC machine tools, ball screws need to have the ability to maintain their original accuracy for a long time. This means that the wear of the ball screw should be minimized to prevent loss of accuracy.

2. Stiffness: The ball screw needs to withstand a large amount of load, so it must have good stiffness. This not only helps to maintain accuracy under load, but also helps to make correct considerations in the structure and material selection of the lead screw.

3. Guidance: Good guidance includes the straightness of movement of moving parts and the smoothness of circular motion. This directly affects the transmission accuracy and motion stability of CNC machine tools.

4. Transmission efficiency: Compared to traditional threaded screw, ball screw adopts rolling transmission method, which significantly reduces sliding friction and greatly improves transmission efficiency. This enables the ball screw to more efficiently complete the positioning and movement of the workpiece in machine tool processing.

5. High speed performance: Ball screw is suitable for high-speed motion because its rolling transmission characteristics reduce friction resistance and allow for higher rotational speeds.

6. Thermal stability: During continuous operation, the ball screw should be able to maintain stable performance even under temperature rise. Thermal stability is crucial for maintaining the machining accuracy of machine tools and extending the service life of ball screws.

7. Compatibility: The ball screw should be compatible with other components of various CNC machine tools, including control systems, guides, bearings, and motors.
