Internal Gear Grinding Machine ZI20A

Achieving both high productivity and high precision through the world's first internal gear grinding technology developed independently.

◆High-efficiency grinding using barrel-shaped threaded grinding wheels (generative grinding process) By adopting barrel-shaped threaded grinding wheels, a larger axis intersection angle is achieved, increasing the grinding speed (slip speed) → Improved cutting performance = high tooth surface correction capability (pitch accuracy also improved) → Improved grinding ratio = extended grinding wheel life (reduced tool costs) ◆Generative grinding through high-speed, high-precision synchronous rotation of the grinding wheel axis and workpiece axis ◆Product detail page https://www.nidec.com/jp/machine-tool/products/B700/M104/S104/NMTJ-zi20a/
