Naoki Ball screws, which are made up of a screw shaft, a ball nut, balls, and a recirculator, serve to translate rotational motion to linear motion. Ball screws are used in machine tools and semiconductor manufacturing equipment. They can also be found in injection molding machines used to produce the smartphone chassis that we all use. Ball screws are in high demand in a wide range of industries including automobile components, such as electric-hydraulic brake systems. Ball screws can even translate linear motion into rotational motion, which is a feature utilized in vibration damper for buildings.
Takashi One characteristic of ball screws is their ability for high-precision positioning. Since they can achieve very precise motion, they can help to increase the precision of machinery. Ball screws can also convert a slight rotational force into a much larger thrust. This characteristic is utilized in machines that need to generate extremely large forces, such as press machines.
