CNC Die Sinking EDM Machine, also known as CNC EDM die sinking and CNC Spark Erosion Machine provided by one of the professional CNC EDM machine suppliers, DMNC, is a kind EDM machine that utilizes high-frequency power between positive and negative anodes (electrode and workpiece), 3-axis or more axes controlled, to break through the gap between electrode and workpiece, to create high temperature to melt and remove metal to get needed profile cavity. It's like a projective copy of the profile of the electrode on the workpiece.

Twin-head large EDM CNC sparking machine has two separated spindle heads and two separated controllers, also called double column large EDM machine, it was developed for some kinds of molds with very large size. Max table size could be up to 3500mm, and load capacity up to 20000kgs. Besides, two separated CNC electric discharge machines could be performed at the same on different locations of one mold. Of course, the dynamic and mechanical of double head CNC EDM is not as good as single-head CNC EDM die sinking EDM machine.
