EA 12S Advance Sinker EDM

Built for aerospace and molding applications – best for medium-sized parts.

The Mitsubishi EA12S Advance represents over 50 years of continuous innovation in sinker EDM technology from one of the most well-recognized industrial machining brands in the world. Sporting a slightly larger footprint that enables greater axis mobility and increased functionality, the EA12S Advance is a compact sinker EDM designed to support various micro-fine machining needs in a productive, cost-efficient way—all while being easy to operate.


  • Highly durable components keep maintenance costs in their place while meeting project requirements.


  • Manages profit margins by balancing resources and energy consumption with high-speed production capabilities.


  • The EA12S is remote360-enabled, letting you react to potential problems in real time to help keep your lines running.


  • FP80S energy-saving power supply achieves 20% less electricity consumption compared to previous models
  • Power Master GF2 adaptive control reduces downtime and minimizes maintenance and part replacement costs by creating 80% less electrode wear
  • SS Jump 5 system grants users greater acceleration control to stabilize high-speed no-flush burning
  • Fuzzy Pro Plus enables greater hands-off operation for better usability
  • PS circuit standard allows for fine finishing


  • FP80S power supply (provides 80 peak AMPs)
  • Compact, highly rigid machine design
