Automatic Transmission (AT) Valves

Unique precision cutting/grinding technologies and surface treatment technology
Valves and sleeves are central parts that ensure the control function of AT vehicles.
These parts, which require the processing of complicated shapes and high-precision finishing,
are efficiently produced by unique precision cutting and grinding technologies.

Apex Seals

Ultraprecision grinding technology
Apex seals for precision parts that influence the performance of rotary engines.
The original know-how acquired through the development of a ceramic apex seal that was equipped in Le Mans is the mother of our ultra-precision grinding technology that is taking on the world of submicron technology.
