The Seibu MM75B/M75B delivers next-generation performance for manufacturers needing high-accuracy EDM machining. These large-format CNC wire EDM machines handle complex geometries, tight tolerances, and extended part sizes with ease. Whether cutting detailed molds or precision aerospace parts, both models maintain consistent, repeatable accuracy.
Each machine comes equipped with Seibu’s Smart NC control. This advanced CNC system simplifies programming and automatically adjusts cutting conditions in real time. Operators reduce setup time while gaining reliable performance and fine surface finishes. Both models also feature Seibu’s patented Automatic Wire Threading (AWF-4). The AWF-4 system anneals and straightens wire, ensuring it feeds through small holes and rethreads at break points. This technology supports uninterrupted machining and enables lights-out operation.
The MM75B/M75B models differ based on the Z-axis travel. The M75B offers a slightly extended Z-travel (750 x 500 x 310 mm), making it ideal for taller parts. The MM75B measures 750 x 500 x 280 mm, remaining suitable for most high-precision applications. Both machines are built with thermal stability, rigid frames, and ultra-precise motion control. Whether for toolrooms, production floors, or job shops, the MM75B/M75B line delivers scalable, production-ready CNC wire EDM solutions trusted by professionals worldwide.
