Electrical Discharge Machining was pioneered by the Soviet researchers Mr. and Mrs. Lazarenko when they were studying the phenomenon and causes of corrosion and damage to switch contacts generated by the spark of electrical discharge in 1941. The Lazarenkos discovered that the instant high temperature of electrical discharge sparks could locally melt and oxidize the metal, leading to its corrosion. This discovery led to the creation and invention of electrical discharge machining methods. The Lazarenkos is often credited with building one of the earliest EDM machines.

Wire EDM(Electrical Discharge Machining) machining or cutting is a specialized machining process for cutting conductive materials – especially carbide alloy or hardened material(heat-treated steel) to high-precision and intricate shapes utilizing electrically charged thin wire through the workpiece.  There are three types of wire material in light of the cutting speed. Molybdenum wire is used for high-speed and moderate-speed wire cutting, while low-speed wire cutting requires brass wire. The molybdenum wire can be reused while the brass wire can’t. The wire diameter ranges from 0.005mm to 0.3mm as per specific application. The low-speed wire EDM has been widely used in the precision die & mold-making industry because of its high accuracy and high-quality surface finish.
