SPECIAL PURPOSE EDM, which stands for Special Electrical Discharge Machining, is a precise machining method used to create intricate shapes in metals that are difficult to machine with traditional techniques. This process involves generating electrical discharges or sparks between an electrode and the workpiece, gradually eroding material to achieve the desired shape.

SPECIAL PURPOSE EDM is widely used in various industries, including aerospace, automotive, and medical device manufacturing. It excels at producing complex and intricate parts, molds, and dies with tight tolerances. Additionally, it offers the advantage of not requiring direct contact between the tool and the workpiece, reducing the risk of tool wear and heat-affected zones.

SPECIAL PURPOSE EDM can be employed for both sinking (die-sink) and wire-cut EDM, making it a versatile machining process suitable for a wide range of components.
