Short answer: Electrical discharge machining (EDM) cuts electrically conductive metal with controlled sparks instead of a cutting tool — so hard, brittle or delicate parts (tool steel, carbide, tungsten) can be shaped to tight tolerance with no mechanical force. Wire EDM slices profiles; sinker EDM burns cavities.
At a Glance
How the Spark Cuts
A servo-held electrode erodes the workpiece in dielectric; relate to Metal Machinability Guide et Metal Grain Size Guide. Hard stock from Tool Steel Supplier et Tungsten Supplier is ideal.
Process Selection
Pick wire vs sinker by geometry; inspect results via Metal Ndt Guide and verify size per Mill Test Certificate Guide. Wear relates to Metal Wear Mechanisms Guide.
