EA8PS Advance Sinker EDM

High-accuracy, high-grade Sinker EDM you can trust – for micro-fine finish, mold & die, or small-hole applications.

The EA8PS Advance can produce a variety of finishes 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.

BUILT TO PERFORM, BUILT TO LAST

  • The Mitsubishi EA8PS 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.

EXTREME VERSATILITY & UTILITY

  • The standard granite table and NP2 circuit provide ultra-fine, satin surface finishing anywhere on the table surface.
  • 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.

COST- AND USER-FRIENDLY

  • The FP80PS energy-saving power supply reduces electrical consumption by 20% (compared to the previous FP model).
  • Like most EDM machines, the EA8PS features the new Mitsubishi M700 series control with a 64-bit RISC processor and 15” touchscreen for easier user interface.
