The EDNC21 machine has a work tank size of 122” x 71” (3,100mm x 1,800mm) and provides X/Y/Z strokes of 78.7” x 59.1” x 31.5” (2,000mm x 1,500mm x 800mm). The machine features dual independent ATC (automatic tool changer) systems, dual independent controllers and dual independent power supplies to facilitate multi-process machining. The ATC system can be configured with a 10- or 32-tool magazine to provide prolonged unattended machine operation. The EDNC21 EDM machine can also be configured with the HS-Rib high-speed Z-axis that achieves jump motions up to 20m/min. The HS-Rib Z-axis maintains high-speed jump motions with precision depth control using integrated core-cooled ball screw construction. The efficiency benefits of the HS-Rib system can reduce cycle time by up to 60 percent, which enables the large EDNC21 machine to attain similar capability and performance found on much smaller machines. 
 
The EDNC21 machine makes use of dual Hyper-i control systems, which provide the ultimate in user-friendly operation and flexibility. Operators of all skill levels will appreciate the graphical nature and intuitive streamlined flow of the Hyper-i control system and will make effective use of the system’s time–saving, on-board digital manuals and advanced E-Tech Doctor help functions. The large 24” class hi-definition touch screen offers an easy, inviting approach to machine functionality. However, the real advantage of the Hyper-i control is its ability to intelligently apply the power of Makino’s advanced technologies, such as HyperCut and SuperSpark™ IV, in delivering the most efficient and productive machine operation.
