Mirror EDM is a kind of EDM technology, which melts the materials in the tool electrode and workpiece, evaporates quickly under the pulse impact force generated by high-frequency electric pulse discharge area, and makes the materials fall off the workpiece. The process of mirror EDM does not need to use mechanical cutting force, which has special advantages different from other machining methods, such as machining extremely hard, brittle, high-strength and difficult-to-machine materials.

Application of mirror EDM in manufacturing industry

Mirror EDM is widely used in various fields of manufacturing industry. It can be used to manufacture high-precision parts or components in aerospace, automobiles, molds, communication equipment and other fields, and can process any three-dimensional curved workpiece, high-precision small parts and complex internal structures. In addition, mirror EDM can also be used to make metal parts modeling and carving, pins, seals, hardness templates and so on.

Comparison between mirror EDM and other machining technologies

Traditional machining will be accompanied by certain impurities, while mirror EDM will not produce chips, fatigue and cracks on the surface, thus ensuring the consistency of surface quality and not losing tools when machining hard materials. Compared with laser machining, EDM has the advantages of high dimensional accuracy and low surface roughness, and is suitable for machining thick metal parts. In a word, mirror EDM, as a unique machining technology, has unique advantages and application prospects.
