Factory Introduction

The latest facilities, reaching the top of the world

For precision machining of race engines, which cannot have even the smallest accuracy error throughout its components, it is absolutely necessary to invest latest cutting-edge technology.

At KOGANEI, we only utilize the latest state-of-the-art precision machining equipment which has been fully customized to meet our specification based on our know-how.
There are no other companies in the machining industry that have the same level of facilities as we do.
KOGANEI's production assembly line including material selection, machining, and inspection of finished products operates 24 hours a day. During the assembly process, machining takes place under strict temperature control, and stricter temperature control is implemented for the measurement process. Our assembly environment is most suitable for high precision machining.
In addition, according to the philosophy of precision machine manufacturing in Switzerland, a rich natural environment is the mother of fine products. Our company shares the same philosophy—our Sayamadai plant is located in Iruma, a unique industrial area in Japan surrounded by tea fields; our Maebashi plant is located in at the foot of Mount Haruna in Gunma Prefecture.

To create “Winning” engines.
KOGANEI is always challenging the cutting-edge technologies.
