Electric Discharge Machining (EDM) is a widespread technique for processing electrically conductive hard materials. During this process the erosion arises through melting and evaporation mechanisms produced by spark plasmas which are created between a tool electrode and the workpiece. In order to adapt the technology to the manufacturing of 3D micro-parts, a specific process control has to be set up so as to meet the constraints of miniaturisation of the electrodes with respect to the repulsive forces coming from the sparks.
Welded with flux cored wire of high hardness for submerged arc welding which is made in our company, and machined with EME machine tool, the roll's life 3 times longer and cost only half than the new one. From prototype to production, Aerospace Techniques is uniquely qualified to meet your EDM machining requirements.
