Spark Erosion

The Charmilles EDM uses 5 axis spark erosion enabling polished tunnel gates at any angle and deep slot eroding quickly and rapidly. Large areas can be simply eroded providing a uniform finish without buring or leving hotspots. Multiple electrodes are able to be used as the machines have electrode or tool changing carousels. Using the latest 3R holding/modular system, electrodes are machined in one setting providing greater accuracy and repeatability.
