Electric Discharge Machine > MMA Series Seibu successfully developed the world’s first CNC Wire Electrical Discharge Machine (W-EDM) in 1972. By adding a variety of functions to the CNC W-EDM, it was reborn as M-series of high-speed, high-precision W-EDM in 2003. And now, our never-ending quest into research for precision led to the development of the MM-series. With a fine and silky smooth motion, an electrode wire can cut metal as desired. Our high standards for precision are proof of a traditional scraping technique called “KISAGE”. The “KISAGE” is repeated until perfection is attained to make very smooth, high-precision finishes on metal surfaces which a machine cannot attain. Seibu will continue to develop new advanced technologies to take that extra step in EDM manufacturing. High quality performance is accomplished in MM series using a traditional scraping technique called “KISAGE”. MM series has achieved cutting accuracy in submicron and long term stable pitch accuracy. Can meet ultra-precision metal mold! Operator can do cutting such as progressive plate cutting with confidence by use of the world’s top-class AWF. This automatically corrects the displacement of wire vertical position due to the surrounding temperature change or effect of the heat by electric discharge. This function can enhance the shape accuracy of product. It is also possible to obtain better cutting accuracy without spending money on temperature control facility. It is possible to monitor various conditions such as [progress], [alarm], [cutting finish], etc. of machine operation status using e-mail by mobile-phone.
