Gantry Eagle 800 Sinker EDM

Best in class for large part and molding applications – low electrode wear and fast cycle times create an excellent ROI.

Combining the latest in technological innovation with a unique, human-centric design, the Gantry Eagle series places top-quality results firmly within reach—without requiring any extra hassle. Plus, with on-board components designed to reduce wear and tear throughout its lifespan—requiring less maintenance and costly downtime—the Gantry Eagle series offers unmatched utility across any number of projects, materials, industries, and more.

The Gantry Eagle 800 has an unexpectedly large, easy-access working area that requires less floorspace than other sinker EDM models, making it an excellent addition to any operation.


The Eagle PowerTec power supply reduces burn time and electrode wear without sacrificing accuracy.

The Gantry Eagle 800 uses the Eagle PowerTec power supply with the world’s first Adaptive Current-Shape generator. Each discharge pulse calculates and creates the ideal current shape to meet the exact discharge requirements at that moment.

  • Eagle PowerTec, combined with Eagle Power Jump, reduces burn time by up to 50% while drastically reducing electrode wear—especially in graphite.


The Gantry Eagle 800 features a dual 32-bit, PC-based CNC control that enables faster data processing and servo control. The machine’s unique construction provides thermal stability and rigidity and features a 4-sided drop tank design that allows work-area access from all sides.


The Eagle Gantry series balances a large workspace with high-precision machining, leading to results your business can comfortably depend on.
