Electrical discharge machining. Electrical discharge machining (EDM), also known as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks).
At 8,157 lbs., the affordable EDAF2 outweighs most machines in its class by more than two to one. The EDAF2 sinker EDM machine, with its fine-hole option, achieves maximum micromachining performance with superior surface finishes. The EDAF3, a larger, more dynamic version of the popular EDAF2, provides shorter machining times, high accuracy, high-quality surfaces, and fine-hole machining in a space-saving footprint.
