Get A Quote

Seibu’s Super MM80B wire EDM is designed to deliver high material removed rates while holding a pitch accuracy of ±1 micron across a large travel in the X and Y axis. Machine castings are ground and hand scrapped for complete flatness. 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 resulting high precision parts. The Smart NC (Fanuc Control) 21.5” touch panel can access all operations like a smartphone. The control has been customized to show more information so operators can check the necessary cutting data or maintenance work on any screen at any time.
