Makino’s EDNC65S RAM EDM combines rugged construction, simple programming and advanced design and performance features. The result is an EDM that machines 30 percent faster than manual EDM machines, while utilizing Makino’s High-Quality Surface Finish (HQSF) technology to achieve superior speeds and finishes. In some applications HQSF technology allows you to machine to a mirror finish without benchwork or polishing.
The Makino EDNC65S features a "drop tank" design that allows for easier, faster, more accurate setups as well as lower mechanical stress during orbiting. Its three-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 EDNC65S a large tank size—1100 x 750 x 450 mm—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 slid-on loading and setup. The EDNC65S comes standard with programmable tank raising and lowering. Adjustable tank depth allows optimal machining of dielectric fluid level to workpiece size—shallow for small jobs, high for large—for overall dielectric savings.
Once loaded, the EDNC65S 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 EDNC65S’ three-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, fine jobs and also deep ribs reliably and accurately without trial runs, regardless of operator skill.
