Capabilities ::: About ECM
The value of electro-chemical machining (ECM) technology is influencing OEM’s to choose ECM in lieu of traditional processes for a wide variety of applications including:


Blades and Vanes

Blisk and IBR’s
Cases and Structures
Helicopter shafts and hubs
Internal tube geometry

ECM allows fast, stress- and burr-free machining of contoured shapes in a single pass. The process works equally well on all metals–regardless of the hardness–including new Titanium aluminides, Titanium-17, Titanium-6-2-4-2, Titanium-6-4, IN100, Rene 88, Rene 95 and Inconel-718. What's more, ECM does not produce a heat-affected zone, a recast layer or a change in the microstructure of the base material.
