High Speed-Precision

Get A Quote

Seibu’s M75B wire EDM is built for large size heavy parts. The machine is designed to deliver high material removed rates while holding a pitch accuracy of ±3 microns. Machine castings are ground and hand scraped 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 in high precision parts. The new 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.
