A few simple tips for maintaining accurate, reliable ball screws. It's relatively simple to determine the lead accuracy of a ball screw before you buy it. Just ask the manufacturer and get a protocol.

It’s a fact of life for CNC router owners — swarf. Whether it’s the fine dust from a sheet of MDF or nice fat chips from a piece of aluminum, the debris your tool creates gets everywhere. You can try ...

This close-up of the ball contact in a profile projector shows a gothic arch. It consists of at least two radii slightly larger than the ball used, but offset so the raceway touches the ball on both ...

Ball screw mechanisms represent a critical class of precision drive components that convert rotational motion into linear motion by utilising recirculating ball bearings. This conversion is achieved ...

Ball screw drive systems are pivotal in modern machine tools, providing the precise conversion of rotary motion into linear movement. Their high stiffness and efficiency render them essential in ...

The PRS models, with G5 lead accuracy, are available in screw diameters ranging from 8- to 80-mm, and deliver static load ratings up to 218,000-lbf. Exlar’s PRR models, with G9 lead accuracy, are ...

Global production network: In February, Schaeffler started production of ball screw drives for steering systems at its plant in Xiangtan, China. Credit: Schaeffler. Schaeffler, a German manufacturer ...

A lot of the projects we feature here on Hackaday engender the classic “build versus buy” argument. We’ve always been puzzled by that; if anyone can appreciate the sheer joy of making something rather ...
