How Does the EDM Process Work?

Electrical Discharge Machining (EDM) is the process of electrically removing hard material from a conductive material. This process is achieved by applying high frequency, pulsed direct current to the workpiece through an electrode, wire, or through a copper or brass tube. The wire or tube melts and vaporizes the workpiece material at approximately 7,500 degrees, coupling with a servo-drive. While never touching the workpiece, an electrode discharges its 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.

Electrical Discharge Machine Advantages

EDMs are used to create extremely precise, exacting cuts in materials too difficult for conventional cutting methods. Using an EDM provides numerous benefits

, including:

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