Micro EDM in a nutshell


Micro EDM (EDM = Electrical discharge machining) refers to spark erosive material removal. These electrical discharges are generated through the smallest amounts of energy. Micro EDM serves both the three-dimensional processing as well as the introduction of smallest drill holes in electrically conductive materials.


Micro EDM is underlied with electrical discharge technology which has established itself for years - from large-scale mould construction up to microsystems technology. As a rule, the term micro EDM is used when the geometry to be manufactured is smaller than 500 μm.


Systems of the latest generation are able to make drill holes with a minimum diameter of 0.03 mm.
