Original Technology and Production System

Production System (as of December 2025)

Gleason cylindrical gear grinding machine #275G

We have 150 or more gear cutting and grinding machines, mainly for spur and bevel gears, producing over 500,000 gears of all kinds every month. JIS Class 0 precision is also available to be comply.
We provide stable, high-quality gears through high-precision equipment and a production system integrated from
design through heat treatment and finishing.

Production capacity is currently being expanded.
