The Mitsubishi EA12PS Advance Sinker EDM 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 improves accuracy by tracking and compensating for machine temperature changes. The standard NP2 circuit provides an ultra-fine, satin surface finishing anywhere on the table surface. An enhanced Glossy Mirror Finishing Circuit “LLTX” improves mold releasability 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. Meanwhile, the FP80PS Sinker EDM energy-saving power supply reduces electrical consumption by 20 percent (compared to the previous FP model). Like most Sinker EDM machines, the EA12PS features the new MITSUBISHI M700 series control with a 64-bit RISC processor and 15-inch touchscreen for easier user interface.
