Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

Lead screws are often called the workhorses of motion control. They consist of a threaded shaft and a nut that carries the load along the shaft or guides the shaft in moving the load, and they derive ...

Knowing the details of a linear-motion application increases the odds of choosing the right ball screw. The more thrust an application requires, the larger the diameter screw will be needed. That’s ...

Inventors have designed tiny, spinning screws that could drill into tumours and kill them. Kazushi Ishiyama at Tohoku University in Japan has invented prototypes of the tiny micromachines. The screws ...

The author describes the benefits, processes, and practicality of using hot-melt extrusion to mix active pharmaceutical ingredients with pharmaceutical-grade polymers. Extrusion technology is a highly ...

For any sort of precision machine, precision adjustability is required. For the hacker this usually involves an adjustment screw, where the accuracy is determined by the thread pitch. This was not ...
