A revolutionary method for the complete processing of worm shaft profiles

Unbeatable cycle time with outstanding surface finish quality

With the JUTWIST 2000 high-speed grinding machine, grinding worm shaft profiles from blank became cheaper, more accurate and faster. The new machine concept makes it possible to grind parts with up to six starts with a clamping length of up to 300 mm and a swing diameter of up to 50 mm – all in a single clamping set-up.

Substituting costly manufacturing processes

JUNKER is replacing today's common manufacturing processes, such as milling, spinning, rolling, with grinding. Grinding eliminates high tooling costs, increases flexibility to produce any thread forms, and provides a single solution for soft and hard material. In short, removing all disadvantages of the current common processes.
