EA12PS Advance Sinker EDM

A highly useful, highly accurate model that can handle all kinds of mold & die situations.

The EA12PS Advance can produce a variety of finishes—and can even handle exotic materials—while still maintaining the degree of quality and high-accuracy precision the world expects from Mitsubishi machines. The EA-PS series offers truly high-grade sinker EDM solutions that generate serious cost savings down the road—from hands-off, low-maintenance components that keep your shop floor humming to intuitive user-focused design that requires less learning, so you can spend more time doing.


  • The Mitsubishi EA12PS Advance with Thermal Buster is the ideal choice for tight-tolerance applications such as die and mold.
  • The new Thermal Displacement Compensation System and Z axis cooling mechanism improve accuracy by tracking and compensating for machine temperature changes.


  • The standard granite table and NP2 circuit provide an ultra-fine satin surface finish.
  • An enhanced glossy mirror finishing circuit, LLTX “Lotus Leaf TeXture,” improves mold release without the need for polishing.
  • If you work with exotic materials such as PCD, cBN, or carbide, the HPS circuit enhances machining speed while reducing electrode wear.


  • The FP80PS energy-saving power supply reduces electrical consumption by 20% (compared to the previous FP model).
  • Like most EDM machines, the EA12PS features the new Mitsubishi M700 series control with a 64-bit RISC processor and 15” touchscreen for easier user interface.
  • High-speed rapid travel: 275”/min.(7m/min.).
  • SS Jump5 with 984”/min.(25m/min.) jump speed @ 1.6G acceleration.
  • Can produce a variety of finishes, including:
    • Ultra-fine matte finishing with the NP2 circuit standard (0.05μm Ra).
    • Fine matte finishes with the PS circuit.
    • Super-low wear with the SC circuit.
    • Glossy mirror finishing with the LLTX “Lotus Leaf TeXture” system.
  • Handles exotic material machining, PCD, cBN,and carbide,with the HPS circuit .
  • Fuzzy Pro Plus enables greater hands-off operation for better usability.
