Mitsubishi Electric MG Series Advanced Wire EDM

The Mitsubishi Electric MG Series Advanced represents the flagship tier of Mitsubishi's wire EDM lineup, incorporating the company's most sophisticated discharge control, axis control, and surface finishing technologies into a platform designed for the most demanding precision die and aerospace component applications. The MG Series targets applications where form accuracy, surface quality, and process repeatability are the primary purchase drivers.

At the core of the MG Advanced is Mitsubishi's next-generation MG power supply, which extends the capability of the Digital AE technology found in the MV-R series. The MG generator operates at higher pulse frequencies and finer energy increments, enabling surface finishes in the Ra 0.05–0.08 µm range on final finishing passes — performance that begins to overlap with precision grinding for flat and ruled surfaces. Form accuracy is held within ±0.001 mm on production runs.

The MG Advanced incorporates a twin-guide system with enhanced wire tension control, minimizing wire deflection and enabling high-accuracy taper cutting up to ±45° with exceptional angularity consistency. Its X/Y travels of 400 x 300 mm and 250 kg workpiece capacity reflect a design philosophy oriented toward precision over raw size — targeting precision punch and die sets, aerospace turbine component features, and medical implant tooling rather than large-format die work.

Mitsubishi's automatic wire threading on the MG Advanced uses a water-jet assist system that achieves reliable threading through small start holes without wire bending, a capability critical when working with fine wire in the 0.05–0.1 mm range. The machine's V550 CNC controller with embedded expert system automatically selects cutting conditions from an extensive on-board database, reducing setup time and enabling consistent results even for less-experienced operators.
