Iiyama Seiki Co., Ltd.

We are expanding our business to other countries with our capabilities of handling Kovar and other difficult-to-process materials as our advantage.

Our company machines and grinds metal parts, mainly up to 50 mm in diameter, by using composite automatic lathes and centerless cylindrical grinding machines. We can handle difficult-to-process materials such as Kovar, titanium, and copper, and also various other types of steel. We have an advantage in high-mix low-volume, high-accuracy processing in Japan. In 2013 we opened a factory in Vietnam for mass production outside Japan. We cover everything from material procurement to grinding and hard turning after outsourced thermal treatment and surface treatment to deliver completely finished products.


[Product description] Our company has particular confidence and experience in processing hard materials such as Kovar, titanium, and Inconel. We meet various customer needs by combining our many years of experience and cutting-edge machining technology. We handle from experimental manufacturing to mass production, including high-mix production in small to medium lots (one to several thousand pieces). We also offer machining with general-purpose lathes and milling machines. We have various kinds of machining equipment, mainly for NC lathing from 0.5 to 60 mm in diameter. Our company also processes super-hard materials such as molybdenum, tungsten, and tantalum.
