Sinker EDM

The EDNC17 machine provides a collection of user-friendly features and advanced technologies that parallel the machining performance and capability of much smaller machines while providing the highest level of productivity. 

The EDNC17 offers the same utility and capability as the smaller EDNC15 machine, but provides larger X/Y strokes and a larger work tank area.  Excellent access to the Work Zone is provided with the 4-sided programmable rise & fall work tank, and this design simplifies the loading and unloading of large work piece details while also minimizing robot automation requirements.  The EDNC17 minimizes floor space requirements by integrating the di-electric reservoir into the base casting of the machine, and this enhances machine thermal stability for greater accuracy.  The machine utilizes a stationary work table design with robust construction to deliver reliable precision, and can accommodate parts weighing up to 22,000 lbs. (10,000kg) or parts as large as 98.4” x 63.0” (2,500 x 1,600).

The machine makes use of Makino’s HS-Rib high speed Z-Axis, which achieves jumps speeds up to 20m/min with 1.0G acceleration, which is an ideal configuration for Die/Mold Rib electrode details and can reduce machining times by up to 60 percent.  The Z-Axis structure also incorporates a core cooled ball screw with a dedicated closed-loop chiller unit to ensure optimal depth control accuracy and proper blending of electrode features over the entire 31.5” (800mm) of travel.  The EDNC17 offers different size ATC (Automatic Tool Change) options, which are located externally from the work tank so that it does not impose stroke or processing limits, to help achieve greater unattended machining operation.

Technical Specifications

The EDNC17 is configured with the advanced SuperSpark IV and HyperCut generator technologies and with Makino’s Hyper-i control system, which empower operators of all skill levels to achieve efficient results with greater productivity.  The Hyper-i control represents a paradigm shift in user-friendliness and operator interaction, and features a graphical intuitive interface using a large hi-definition 24” class touch screen.  The Hyper i control embraces a familiar smart-device or tablet-like functionality for an extremely short learning curve, and the system evokes higher level capabilities with the embedded on-machine support functions such as the EDM Assist digital manuals and video tutorials, and the practical E-Tech Doctor advanced help function that provides a graphical tool to make expert-level changes to machining conditions.
