EDM machines

Electrical discharge machining processes conductive materials without direct mechanical contact between tool and workpiece. Wire EDM suits accurate contours and through profiles, sinker EDM creates cavities and negative forms, while EDM drilling produces small holes and wire start channels. The technology is widely used in toolmaking, dies, medical components and precision parts.

Machine selection depends on workpiece size, travels, thickness, finish, accuracy and productivity. Generator performance, discharge control, wire guidance, dielectric management and thermal compensation influence the result. Cavity work also requires evaluation of electrodes, automatic changing and roughing-to-finishing strategy.

Mepro reviews geometry, material and surface requirements to select the appropriate process and configuration. Consulting covers integration into the toolroom, accessories and consumables, while the technical team provides installation, training and service in Romania.

The final recommendation also accounts for utilities, available floor space, operator access, safety and the way the new equipment will connect to upstream and downstream operations. Every capacity or availability statement is confirmed for the selected model in the technical proposal. This keeps comparison grounded in the actual part and production target rather than generic catalogue limits.
