Methods Machine Tools Inc. has introduced the new Fanuc RoboCut iE wire EDM series, which have a new power supply for accurate and efficient cutting performance in challenging materials. Additional new features include a redesigned lower arm and controls for improvements in efficiency, cutting speeds and energy savings, according to the company. Seven-axis simultaneous machining is an option. "The Fanuc iE wire EDMs are capable of increased geometric accuracy to less than 0.0001" and virtually no recast," said Steve Bond, national sales manager for Fanuc RoboDrill, RoboCut and EDM products at Methods. "For example, recast is virtually undetectable at 1000:1 magnification in high-nickel alloys." The machines are suitable for EDMing a wide range of materials, including cobalt-chrome, high-nickel alloys and titanium. The machines feature an upgraded Ai Pulse Control II, providing high-speed and accurate cutting for stepped workpieces by enabling optimal control based on the accurately detected number of discharge pulses. The Ai pulse control also ensures a minimized witness line at both the wire approach and step point, in addition to improved oval shape and small round hole accuracy. A redesigned lower arm incorporates a system that isolates the lower arm power feed contact during final cuts. This reportedly improves finishes during skim cutting with less passes, straighter parts and improved cutting speeds. A new energy-saving function displays power consumption in real time along with cumulative electric power. The energy saving setting reduces surplus electric power during idle time, reducing overall electrical consumption by up to 20 percent. To significantly reduce operating costs and heat output, the iE Series uses high-efficiency inverter-style chillers. In addition, the Fanuc Auto Wire Feed system has been enhanced to thread while submerged through the start hole of a workpiece with a maximum thickness of up to 8.0" (200mm). In the event of a wire break, the auto wire repair system can thread through the kerf while submerged to a depth of up to 6.0" (150mm) without returning to the start point.

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • electrical-discharge machining ( EDM)

    electrical-discharge machining ( EDM)

    Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • kerf

    kerf

    Width of cut left after a blade or tool makes a pass.

  • wire EDM

    wire EDM

    Process similar to ram electrical-discharge machining except a small-diameter copper or brass wire is used as a traveling electrode. Usually used in conjunction with a CNC and only works when a part is to be cut completely through. A common analogy is wire electrical-discharge machining is like an ultraprecise, electrical, contour-sawing operation.
