Used Mitsubishi Electric EA28 Advance: Sell or Buy at Auction
Mitsubishi Electric is a major Japanese manufacturer of wire EDM and sinker EDM machines, as well as laser cutting systems. Mitsubishi EDM machines are known for advanced power supply technology, superior surface finish capability, and the industry-leading Advance CNC control. The FA Series wire EDMs are a standard in die and mold shops, medical device manufacturing, and precision machining.
The Mitsubishi Electric EA28 Advance is a die-sinking, or ram, EDM built to burn cavities, cores, ribs, and fine surface detail into hardened tool steel rather than cut a profile clean through it. A larger-format machine in Mitsubishi's EA Advance sinker lineup, it carries X and Y travels of roughly 25.6 by 17.7 inches over a worktable near 33 by 24 inches, with enough vertical (Z) travel and full-immersion dielectric to sink deep cavities in tall mold blocks. It accepts electrodes up to about 50 kg and runs on Mitsubishi's Advance control platform. That envelope reaches mold base and larger die work: the cavity and core burning that outgrows a bench-scale sinker but does not call for a wire EDM's through-cutting. Mold shops, die shops, and precision toolmakers bid on the EA28 Advance for exactly that reach, and KD Auctions puts machines like it in front of 500,000+ industry contacts across die, mold, and precision machining operations.

Frequently Asked Questions
What is a used Mitsubishi EA28 Advance sinker EDM worth at auction?
Resale value depends on the machine's age, hours, and overall condition, whether the control and generator are fully functional, and what tooling comes with it, such as electrodes, fixturing, and any orbiting or C-axis attachments. Rather than quote a number sight unseen, KD Auctions provides a free, AMEA-accredited and USPAP-compliant appraisal that establishes both orderly liquidation value (OLV) and forced liquidation value (FLV), so you know where your specific unit stands before you decide to sell.
How is the EA28 Advance different from Mitsubishi's FA Series wire EDM machines?
The EA28 Advance is a die-sinking EDM: it plunges a shaped graphite or copper electrode into the workpiece through dielectric oil to form cavities, cores, and blind or textured detail that a wire cannot reach. Mitsubishi's FA Series machines are wire EDMs, threading a fine traveling wire through deionized water to cut profiles all the way through stock. Shops building mold cavity halves and core detail reach for a sinker like the EA28 Advance, while shops cutting punches, dies, and through-features from plate look to the FA Series. Many toolrooms run both.
