A reliable integrated production system that achieves high quality and low cost.
We strictly control all processes from raw material processing to finishing.
In order to provide high-quality products more speedily and at lower cost, it is necessary to implement integrated production from raw material processing to finished-product processing in-house. We have been working on building an "automated, integrated production system" from an early stage. We will continue to improve our production processes in order to respond to the diversifying and increasingly precise needs of our customers.

Rolling and forging process
Lathe process

Broaching process
The inner gear is processed using a broaching machine.
Allows processing with high precision and speed.

Gear shaping process
Allows cutting of stepped gears, special gears (missing teeth), etc., which cannot be processed by the hobbing machine.
Chamfering process

Hole-making process
Hole-making with machining.
A single machine can drill holes of multiple diameters.
