Pursuing high precision and high quality

We offer narrow tolerance products based on our processing technology and ingenuity accumulated over many years.
Example
+0/-0.004mm tolerance for 19.00mm outside diameter

The bending condition of the shaft greatly affects the product characteristics.
We are promoting the development of high straightness products.
Example
Run-out of 0.01mm or less for a span of 300mm

Internal stress always occurs in cold drawing steel.
Internal stresses are released during machining, which adversely affects part quality and accuracy.
We have already established a cold drawing technology that reduces internal stress, and we have received favorable comments from many customers.
In addition, regarding internal stress reduction technology in cold drawing, we have announced the results of many years of research at academic conferences.

The grinding technology that we have cultivated over many years has enabled high precision grinding of not only metal products but also non-ferrous metals such as brass and aluminum, as well as various resins.

“Offensive quality” that responds to user needs that are increasing day by day, and “defensive quality” that makes use of many years of experience.
We maintain both offensive and defensive quality through ISO9001, and promise high quality through synergistic effects.

Hints for the birth of manufacturing technology for high quality, high precision products can be found at the production site.
We value the opinions of the production site, and in order to establish new technology, we are working daily on prototyping and process improvement (Offensive quality) centered on the Innovation Department.

Support for users includes technical advice before purchasing the product and after-sales follow-up.
Our technical support department works with the sales department to meet user needs and serves as a conduit for user evaluations to each factory, working to maintain and improve quality (defensive quality).
