Fanuc iC wire EDMs deliver cutting speeds up to 31 in. 2 /hr with uncoated brass wire and 33.6 in. 2 /hr with coated wire. R1 technology monitors effective pulses and adjusts machine feedrates to maximize cutting speed and minimize wire breaks. A workpiece thickness adaptive control function checks workpiece thickness variations and automatically adjusts cutting current to, reportedly, reduce overall machining time by 30%.
Fanuc's auto wire feed system anneals, cuts, moves, threads, and starts discharges. It threads 0.010-in.-diameter wire through start holes as small as 0.015-in. in diameter while parts are submerged.
