Seibu - Manufacturing wire EDMS since 1972

KGK International is the North American importer for Seibu high quality wire EDM machines which are 100% made in Japan. Seibu is the only EDM manufacturer who guarantees a pitch accuracy down to ± 1μm. Although new to the U.S. market, Seibu has a long history. They created the world’s 1st CNC wire EDM in 1972. The wire EDMs are built in Seibu’s ISO certified factory in Koga City, Fukuoka Prefecture which is located in southern Japan. Seibu machines target the high end precision wire EDM market which requires a quality machine designed to last and produce consistent results. Only 30 to 40 individually created high quality Seibu machines are hand crafted per month. Seibu manufacturing philosophy is about quality and not quantity. High end brands are rarely the most popular but always offer the highest quality. All machine castings are hand scrapped which uses a blade to remove high spots left behind by during the machining process resulting in improved part geometry, repeatability & surface finish. Guideways are checked for flatness, lasered for straightness and test cuts are performed on all machines which are then checked on a CMM for accuracy.  Since Seibu machines manufactured in Japan, they are built for precision and will outlast and out perform the competition.
