Makino EDNC-17

The Makino EDNC-17 takes the EDNC-15 and widens the envelope: 1,700 x 1,150 x 800 mm (66.9 x 45.3 x 31.5 in) of travel over a 2,000 x 1,350 mm (78.7 in x 53.2 in) table, rated for 10,000 kg (22,046 lb). Makino describes it as offering the same utility and capability as the smaller EDNC-15 with larger X and Y strokes and a larger work tank.

Y travel is the change that matters. The EDNC-15 has 700 mm (27.6 in) of Y and a 1,000 mm wide table; the EDNC-17 has 1,150 mm (45.3 in) of Y and 1,350 mm of table width. Wide die halves, or several cavities laid out across the table, can be reached without moving the part.

Makino's description includes the HS-Rib high-speed Z-axis without calling it an option. It reaches jump speeds up to 20 m/min with 1.0G acceleration, uses a core-cooled ball screw with a dedicated closed-loop chiller unit, and covers the full 31.5” (800mm) of Z travel to keep depth control and blending of electrode features consistent. Makino aims it at die and mold rib electrode details and says it can reduce machining times by up to 60 percent.

The 4-sided programmable rise-and-fall work tank measures 2,500 x 1,600 x 800 mm (98.4 in x 63.0 in x 31.5 in), and Makino gives 98.4” x 63.0” (2,500 x 1,600) as the largest part size. Dropping all four sides simplifies loading large details and reduces what robot automation needs. ATC options of different sizes, with 8, 16 or 32 tools in the table, are mounted outside the tank.

Electrodes can weigh up to 100 kg (220 lb), the generator row reads 60A ~ 240A, and rapid traverse is 5,000 mm/min (197 ipm). SuperSpark IV and HyperCut run from the Hyper-i control on a 24” class touch screen.
