Company profile, offices, and history.

Since our founding on January 20, 1961 by former president Mr. Torimatsu Kikuchi, Kikuchi Seiki has specialized in precision machining, focusing on electrical equipment components, general mechanical parts, and precision machining of printing machine components. On June 21, 1979, the company's name was changed to 'Kikuchi Seiki Co., Ltd.' Then, in December 1983, we completed our “Second Factory,” establishing a production system that allows us to deliver finished products through machining, surface treatment, unit assembly, and more. In May 1995, we constructed the Mukoyama Factory and consolidated our equipment to this location. In February 2006, we introduced a surface plate and welding machine to the second factory, which began operation as a sheet metal processing facility. In July 2007, we completed our large-scale machine processing factory and shifted our focus to processing large machine parts. In August 2016, we obtained JIS Q 9100 certification for 'Machining of Forged Products for Aircraft Engines' at the Mukoyama Factory.
