The Makino EDNC65 features a “drop-tank” design that allows for easier, faster, more accurate setups as well as lower mechanical stress during orbiting. Its 3-axis head allows superior dynamic control, burning precision and machine response compared to machines that move the table for axis positioning. The drop-tank design integrates the rear wall of the tank with the machine base for space and strength gains. The design gives the EDNC65 a large tank size—1,100 x 750 x 450mm—while allowing for an even more massive base. A U-shaped continuous structure provides the other three walls of the tank body. The structure retracts completely into the machine table. Retractability provides open access to the table for safe, simple slide-on loading and setup. The EDNC65 comes standard with programmable tank raising and lowering. Adjustable tank depth allows optimal matching of dielectric fluid level to workpiece size—shallow for small jobs, high for large—for overall dielectric savings.
Once loaded, the EDNC65 is equally easy to operate. Master “model plan” menus allow simple selection and input of the machining conditions for the desired feature shape and surface finish—then automatically calculate machining time. Graphic prompts allow automated programs to be created without NC programming. Macro-based software optimizes orbital motion machining by the EDNC65’s 3-axis head for superb finish, sharp corners, precise detail and the creation of complex shapes with fewer electrodes.
Automatic tool change and adaptive controls enable high levels of unattended machining. “A-Jump”—automatic jump machining control—sets jump conditions to the machining job, eliminating the need for operator intervention. This makes it possible to machine small, finely detailed jobs, and also deep ribs, reliably and accurately without trial runs, regardless of operator skill.
