EDM (Electrical Discharge Machining) is a non-contact machining process that uses electrical discharges between the electrode and the workpiece to remove material. It is particularly suitable for machining difficult materials (e.g. very tough or brittle materials) as long as these are sufficiently electrically conductive. This quality is enhanced in the ‘micro’ version of the process, improving both machining precision and surface finish by allowing micrometric (<50 µm) and high form ratio geometries to be produced.
The laboratory is equipped with state-of-the-art equipment for high-precision micro EDM, capable of 3- or 5-axis machining, both drilling and milling, with wire and die-sinking EDM. The laboratory also has optical instruments for dimensional characterisation and analysis of the surface quality of manufactured components.
