Electrical Discharge Machining (EDM)
Electrical Discharge Machining (EDM)
Electrical discharge machining (EDM) is a non-traditional form of precision machining that uses thermal energy instead of mechanical force to remove material from a workpiece.
EDM contains Wire erosion and Spark erosion. Wire erosion is a precision engineering process that involves cutting a workpiece with a strand of wire. Spark erosion, also known as sinker EDM or Die-sinking EDM, is a process to shape and form metal parts with high precision.
Wire erosion
The production method for extreme accuracy
Wire erosion is a form of electrical discharge machining (EDM) that makes it possible to machine hard materials with an accuracy that few other methods can match.
Wire erosion uses a thin, electrically conductive wire – preferably in the form of a Ø0.25mm coated brass wire – as a tool for cutting or shaping metal. The wire moves through the workpiece without touching it directly.
Spark erosion
The production method for complex shapes
Spark erosion is often used when there is a need to create very complex, precise shapes, preferably in hard materials such as iconell, duplex, superduplex or other steel and metal alloys.
Flexibility in design – The electrode can be precisely shaped to the desired geometry, allowing the creation of highly intricate details, deep cavities and complex structures that would be difficult with more traditional machining methods.
Reliability – From planning to the part being fully machined, the entire process is characterized by a systematic approach where nothing is left to chance. This combination of technology, experience and accuracy ensures that the end result is reliable and durable.
Optimum for advanced solutions – When the accuracy, shape of the part or the type of material mean that other machining methods are not sufficient, deep-sinking can be the solution – both in terms of quality and precision.
