The FANUC iD Series wire EDM machines offered by Methods EDM Division of Methods Machine Tools, Inc. (Sudbury, MA) feature a beefier, CAD-designed cast Meehanite base that is thermally insulated and 40 percent more rigid than previous models. Table travels are increased with no load overhang during table movement, providing high rigidity even for heavier workpieces. Heavy-duty 1.26” (32 mm) ball screws for the X and Y axes are double-anchored and encapsulated in “bellows” style covers to prevent contamination. Even the ball screws for the U and V axes are 0.79” (20 mm) in diameter. iD Series machines are equipped with FANUC’s most powerful EDM CNC control yet—the 310iS-WA. The FANUC AWF (auto wire feed system) has an Air Jet wire transport system in the upper annealing pipe improving accuracy, reliability and speed. The twin-servo wire-tension-control system ensures the highest possible part accuracy and quality by reducing tension variations to ¼ that of conventional machines. Patented FANUC R Series adaptive-control technology counts real-time effective discharge pulses in the cutting gap and continuously adjusts discharge energy density and gap, providing optimum machining speed and control on complex workpieces with steps or corners, even in poor flushing conditions on the toughest materials. Digital nano interpolation and corner control ensure smooth cutting and accurate part geometry. Servo-driven tank valves ensure that the water level automatically follows the Z axis position, preventing lines on the work surface—common with conventional machines—caused by the opening and closing of solenoid valves.
