What is Electric discharge machining（EDM）？

Electric Discharge Machining (EDM) is a manufacturing process that uses electrical discharges (sparks) to remove material from a workpiece. It's also known as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion.

EDM is commonly used in industries where traditional machining methods are impractical or ineffective, such as aerospace, automotive, medical device manufacturing, and tool and die making. It's especially useful for machining complex shapes, hardened materials, and materials with very high strength or hardness, such as hardened steel and titanium alloys.

How does EDM Cutting work

It uses a thin single-strand metal wire that acts as a tool electrode to generate heat to cut a linear line through a metal workpiece. The thin wire creates an intense electrical spark that erodes the part’s material with exacting precision without physical pressure.

We use wire EDM for projects that have intricate tolerances, material stress limitations, and surface finish specifications. The number of passes to cut the workpiece affects tolerance and surface finish. More passes deliver a higher degree of precision and better finishes.

For high-volume projects with material too brittle for stamping, wire EDM offers a viable alternative. We stack work material in flat layers so we can cut through the stack for a high volume of precision parts.

Wire EDM cutting contours any conductive material difficult to shape with conventional machining techniques. Conductive metals include alloys, superalloys, steel, aluminum, brass, bronze, copper, carbon graphite, carbon steel, stainless steel, and titanium.
