EDM wire cut machines, EDM die-sinking machines and EDM hole drilling machines are the key technologies in mold and tool making. This EDM machinery is manufactured by GF Machining Solutions.
Their EDM machinery can be used to machine conductive materials of any hardness to an accuracy of up to one-thousandth of a millimeter with no mechanical action.
Wire EDM machine uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting.
