Description
EDM drilling machine D7703F is mainly used for machining stainless steel, hardened steel, hard alloy, copper, aluminum and other conductive material on the workpiece diameter fromΦ0.3 mm -Φ3 mm between deep holes. The depth-diameter ratio is over 200:1. EDM drilling machine D7703F can also be used to remove bits and hammers broken in the workpiece without damaging the original holes or threads.
