Spark erosion allows us to achieve intricate details inside components that would, otherwise, be too complex or impossible to obtain with traditional cutting methods and is especially useful for the machining of hard materials such as mould tools, or for removal of broken taps. It also allows for a good surface finish and the drilling of very small and complicated shapes. Because there’s no contact between the tool and the piece, intricate sections or weak materials can be worked on without distortion. If materials have a minimum electrical conductivity of 0.01 S/cm, then it’s likely they can be machined with spark erosion. Like Wire EDM, Spark Erosion can be used for applications where the adherence to tight tolerances of 0.1 microns is key.
