What is EDM (Electrical Discharge Machinery)? It is the process of electrically removing hard material from a conductive material. This is achieved by applying high-frequency, pulsed, DC current to the workpiece through (a) an electrode, (b) wire, or (c) a copper or brass tube, which melts and vaporizes the workpiece material (approximately 7,500 degrees), coupled with a servo-drive. An electrode never touches the workpiece but discharges it's current through an insulating dielectric fluid (water or oil) across a varying small spark gap. This spark vaporizes and melts the workpiece material. The servo-system controls this spark gap.

The following is a partial list of conditions that can be addressed with an EDM machine.

  • Small interior radius
  • Slight to extreme taper to part walls
  • Virtually burr less machining
  • Working with difficult hard materials and alloys
  • Extreme accuracy to side wall and straightness in "thick" components
  • Ability to cut submerged
  • Fine surface finishes
  • Four axis machining capability
