Basic Concept of Wire EDM

Wire EDM machining (Also Known as Spark EDM) use brass wire as electrode that comes off a spool and is fed through an upper and lower diamond guide and then discarded after it is used. In conjunction with de-ionized water (used to conduct electricity), the wire electrode cut through metal by the use of heat from electrical sparks.
The wire is controlled by a CNC control which allows you to program a path for the wire to travel along sort of like a super precision band saw. The wire can range from 0.10-0.30mm or ( .0120 to .0008 inches ) in diameter.
Due to the inherent properties of the process, wire EDM can easily machine complex parts and precision components out of hard conductive materials. This form of EDM stands the most accurate machining method and is able to hold size well and exact within .0001 inches.
