EDM the Process

EDM is a high precision metal removal process that uses thermal energy from a fine, accurately controlled electrical discharge -spark to erode - vaporize metals.

The scope of the EDM process ranges from the drilling of micro-holes that are smaller than a human hair to machining 100,000 pound automotive dies. In EDM, the workpiece must be electrically conductive and the machining gap submerged in a dielectric fluid. In the EDM sinking process, the inverted image of the tool electrode is gradually impressed in the workpiece.

Although each machine type is significantly different in design and application, they all use thermal energy produced by pulsed spark discharges for metal removal. The two primary types of EDM systems are "Die-Sinking" and "Wire" EDM. Die-Sinking machines are also called Sinker, Ram-Type, Conventional, Plunge or Vertical EDM.
