Ball Screw Introduction

The ball screw is a high-precision and high-efficiency transmission component, widely used in CNC machine tools, industrial robots, precision measurement instruments and other fields. It consists of three main parts: screw, ball and ball holder. The balls roll in the helical groove of the screw, achieving precise linear motion. The ball screw has the characteristics of high transmission efficiency, high positioning accuracy, low friction resistance, and long life span, and can meet various high-precision and high-efficiency transmission requirements.

In CNC machine tools, the ball screw is one of the important components for achieving high-precision positioning of the feed system. Its processing accuracy and assembly accuracy directly affect the machining accuracy and performance of the machine tool. The ball screw can also achieve rapid feed and high-speed cutting, improving processing efficiency and quality.

The following are the main parameters of the ball screw and their significance:

Parameter name | Definition and significance 

Transmission efficiency | The transmission efficiency of the ball screw is the ratio of its transmitted power to the input power, indicating its energy conversion efficiency. 

Positioning accuracy | The positioning accuracy of the ball screw refers to the accuracy of its output shaft's movement within a certain range. 

Friction resistance | The friction resistance of the ball screw refers to the friction force acting on its movement, affecting its movement smoothness and efficiency. 

Lifespan | The lifespan of the ball screw refers to the length of time it can operate normally, usually measured in hours. 

In summary, the ball screw is an important transmission component, and its performance and processing quality have a significant impact on the safety, stability, and precision of various equipment. By understanding its parameters, we can better choose and apply the ball screw.
