Ball screws are mechanical linear actuators that convert rotational motion into precise linear movement through a system of recirculating balls. Unlike traditional sliding mechanisms, recirculating ball screws use rolling contact to minimise friction, increase efficiency and maintain high repeatability. 

In machine tool and industrial automation applications, precision ball screws provide the accuracy, rigidity and smoothness required for tasks such as cutting, milling, drilling and high-precision positioning. 

What is a ball screw in a CNC machine? 

A ball screw CNC machine uses ball screws to control the movement of its axes with high accuracy and minimal backlash.Their low friction and high rigidity allow CNC machines to achieve the tight tolerances and repeatability required in precision machining. 

How do ball screws work? 

Recirculating ball screws operate by using a threaded shaft and a nut filled with ball bearings that circulate continuously within the raceways. As the shaft rotates, the balls roll between the nut and the screw, converting rotation into smooth and efficient linear motion. This rolling contact reduces wear, increases durability and provides consistent positioning accuracy even at high speeds or under heavy loads.
