Manufacture of precision machine parts

[Strength of products/technologies]
Our first product developed within the company is a precision rail cutting machine that can cut a 60 ㎏ rail in three minutes. Then we developed and commercialized our rail drilling machine "Kabutomushi (stag beetle)," These two machines are highly appreciated in the railway industry and a total of 2,000 units have been delivered to JR and other railway companies. These machines are patented in Japan and also in the United States and Taiwan. Gears are the epitome of our technology. We manually manufacture gears individually as small-lot high-precision parts to meet large-variety small-lot production needs.
