The Basics to Wire Erosion

The Basics to Wire Erosion. EDM (Electro Discharge Machining) Wire Erosion is a precision engineering process where a work piece is cut through with a strand of wire, it creates electrical sparks between the wire and the work piece, and these electrical sparks cut the work piece. It's a costeffective method that has incredible accuracy on thicker component parts.
