■Our Strengths

Abundant equipment and skills

We have an abundance of industry-leading machining equipment such as a simultaneous five-axis machining center, a CNC composite lathe, an NC automatic lathe, a cylindrical grinding machine, and a centerless grinding machine.

A 99% rate of “on-time deliveries as promised” thanks to our in-house production management system (FY2017)

Our manufacturing process is visualized through our production management system, which is created with our own IT technology, so that we can track the progress of the process conveniently. Through such innovations, we aim for increased efficiency in production.

Cultivating engineers and handing down skills

We train skilled workers to be certified by the Ministry of Health, Labor and Welfare and we teach these engineers the technology of the NC processing machines as well as general-purpose lathes, milling machines, and others so that the technologies do not die out.

Original tools

Since our founding, we have been refining the techniques needed to produce cutting tools from hard base metals while incorporating the opinions of our mechanical engineers. With our processing know-how, we can efficiently manufacture these tools, which also demonstrates our strengths in cost reduction.

Microprocessing technology cultivated in the medical field

We are skilled in the fine processing and strict safety requirements such as those needed for medical endoscopes and implants that are to be used for the human body. Our in-house made manufacturing tools and fine processing technologies are utilized for more than just medical equipment.

Achievement record of machining aircraft parts
