EDM Combining traditional manufacturing practices and techniques with the
latest technology

Seibu created the world’s first CNC wire electrical discharge machine (W-EDM) in 1972. Since then, we have steadily improved the productivity and precision of our expanding line of W-EDM systems. Adding new functions, Seibu is constantly researching and improve the user's productivity. Seibu developed oil type Ultra Precision Wire EDM "M25LP" which brings EDM manufacturing to a wider range of products. M25LP is ideal, for the manufacturing of lead frames, carbide machining, small electronic and medical components. The secret behind our unsurpassed precision is repeated "Kisage" hand scraping, while attaining a level of flatness that cannot be reached with machining.
