Electrical discharge machining

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 cost-effective method that has incredible accuracy on thicker component parts. Wire cutting machines can cut complex shapes even in tough materials.

The sparks are extremely controlled and in the more recent years to make sure that the cutting is accurate, dielectric deionised water is used. The water acts as a coolant to make sure the metal components don’t overheat and to wash away any particles that could get in the way. The wire erosion process starts towards the edge of a work piece or by drilling a hole where the process will start.
