With exceptionally fast cutting speeds, auto wire feed system, and powerful EDM CNC, Fanuc iC Series Wire EDM machines from Methods Machine Tools (Sudbury, MA) are available in five models with Z-axis heights to 16” and can be seen at Westec. These machines provide exceptional accuracy and surface finishes and come standard with features including artificial intelligence cutting functions, microfinish power supplies, digital servo systems, linear glass scales, tooling packages, high-pressure flushing, chiller units, and quick-change cartridge filtration systems. With five microprocessors to control artificial intelligence cutting functions, graphics, keyboard, and power supply, the Fanuc 180is-WB CNC is fiber-optically interfaced to perform eight times faster than any other EDM control. Using economical brass wire, these machines offer the fastest cutting speeds of any wire EDM—31.0 inches2/hour with uncoated wire and 33.6 inches2/hour with coated wire. Revolutionary R1 technology monitors the number of effective pulses per second and adjusts the machine’s feedrate to maximize cutting speed and minimize wire breaks, even on difficult jobs such as those involving PCD. A Workpiece Thickness Adaptive Control function monitors thickness variations in the workpiece and automatically adjusts cutting current, reducing overall machining time by 30 percent. High Response Vector Control helps provide true circular accuracy and excellent vertical straightness. Noncutting time is reduced and productivity is further enhanced by Fanuc’s Auto Wire Feed System, which anneals, cuts, moves to a new location, threads, and begins discharging—spark-to-spark in only 18 seconds! It can thread .010” diameter wire through a start hole as small as .015” while the workpiece is submerged. A 35-pound wire spool allows the completion of complicated jobs with longer run times. With a fully integrated 6-axis robot and exclusive cell-control software, Fanuc iC Series machines can run unattended for extended periods, making “lights out” manufacturing a reality.
