The EDM is suitable for electrically conductive materials. The average roughness generated surface reaches up to 50 nm and it is possible to generate cost structures associated with conventional machining processes are sometimes not produced. Also, conductive ceramics such as silicon carbide, sintered certain materials can be processed.

The wire EDM (WEDM) with its up to five simultaneous axes makes traveling with wire diameters from 0.02 mm to 0.25 mm in the manufacture of complex three-dimensional geometries with a high degree of dimensional accuracy. The program is created according to the requirements of the workpiece geometry rather than on the machine or to CAM workstations. For one Drahtersosion Charmilles Robofil 4020 related to water and Agie Charmilles CUT 1000 with oil as the dielectric is available. Our CNC EDM machine from Agie Agietron the exact features a finely tuned pulse generator.
