1. Definition
A ball screw is a mechanical precision component that converts rotational motion into linear motion and vice versa. It consists of a threaded shaft and a nut, within which balls circulate to reduce friction, allowing efficient, precise, and nearly frictionless force transmission. Ball screws are used in high-precision machinery and applications because of their high positioning accuracy and low friction losses.
2. Application Areas in Industry
Ball screws are widely used in various industries that require precise and low-friction movement:
-
Mechanical Engineering: Ball screws are extensively used in machine tools, CNC machines, and machining centers where precise positioning and high repeatability are essential for manufacturing.
-
Automation and Robotics: In the automation and robotics industries, ball screws enable precise control of linear axes. They are crucial for high-speed and accurate movement in pick-and-place systems and conveyor belts.
-
Medical Technology: In medical devices such as CT scanners and surgical robots, ball screws are used for precise positioning and movement, where high accuracy and reliability are critical.
