The EDNC15 offers ATC (automatic tool changer) options to help achieve greater unattended machining time. 

The EDNC15 is the 4th machine in the EDNC-Series line-up, and accommodates large heavy work piece details.  The robust machine design delivers outstanding accuracy with its stationary work table construction and greater thermal stability, which is achieved by integrating the di-electric reservoir into the base casting which also reduces the machine footprint while providing support for parts weighing up to 22,000 lbs. (10,000kg).  The machine offers an X/Y/Z stroke capability of 59.0” x 27.6” 19.7” (1,000 x 600 x 500mm). The machine utilizes a 4-sided programmable rise & fall work tank that provides extremely easy access to the work zone for the operator, and the work tank system greatly simplifies the requirements and integration of robot automation.

The EDNC15 features Makino’s revolutionary Hyper-i control system, which represents a paradigm shift in user-friendliness and operational efficiency. The Hyper-i control empowers operators of all skill levels to achieve productive results with fast cycle times using the advanced SuperSpark™ IV and HyperCut technologies. The Hyper-i control features an inviting and intuitive interface with a graphical hi-definition 24” class touch screen and enables higher-level capabilities with the embedded on-machine support of the EDM assist digital manuals and practical E-Tech Doctor advanced help function.

Technical Specifications

The EDNC15 offers ATC (automatic tool changer) options to help achieve greater unattended machining time. The ATC system is located externally from the work tank so as not to impose stroke or processing limits. The optional HS-Rib high-speed Z-axis can reduce machining times by up to 60 percent on small details such as support ribs while maintaining precise depth control. The HS-Rib option includes a dedicated closed-loop chiller unit and a core-cooled ball screw Z-axis structure and permits high-speed jump motions up to 20m/min with 31.5” (800mm) of travel to reach any work piece feature. The user-friendly features and advanced technologies found in the EDNC15 enable machining performance similar to smaller machines while providing the highest level of productivity.
