MDI uses EDM machines to cut very intricate shapes and precise forms from hard metals. This FANUC machine is capable of cutting slots as small as .0070” wide and internal radii as small as .0035”. It is also used for producing extremely smooth finishes up to 13 RMS.
The EDM process does not induce mechanical stress into the metal as it cuts, because rather than shearing the metal away from the workpiece, the wire EDM uses electrical discharges to erode or “melt” the metal away.
MDI also uses EDM machines to design and cut fixturing for use in simultaneous multi-part production.
