The FANUC RoboCut iE Wire EDM series features a new power supply for accurate and efficient cutting performance in challenging materials, the company says. Other features include a redesigned lower arm and controls for improvements in efficiency, cutting speeds and energy savings. According to the company, the recast layer is virtually undetectable at 1000:1 magnification in high nickel alloys like Inconel and Waspaloy. The machines are also suitable for machining cobalt-chrome, high-nickel alloys and titanium materials for applications in aerospace, medical and military.
The machines feature an Ai Pulse Control II, which provides high speed and highly accurate cutting for stepped workpieces by enabling optimum control based on the accurately detected number of discharge pulses, the company says. The Ai pulse control also reduces the witness line at both the wire approach and step point, in addition to improved oval shape and small round hole accuracy.
The redesigned lower arm incorporates a system that isolates the lower-arm power feed contact during final cuts. This design is said to improve finishes during skim cutting with less passes, straighter parts and improved cutting speeds. An energy-saving function displays power consumption in real-time. The energy saving setting reduces electric power usage during idle time, thus reducing overall electrical consumption by as much as 20 percent. In addition, the auto wire feed system can thread while submerged through the start hole of a workpiece as thick as 8.0" (200 mm). If a wire breaks, the auto wire repair system can thread through the kerf while submerged to a depth of 6.0" (150 mm) without returning to the start point.
