Ibarmia SA specializes in high-productivity machining centers with fixed tables and movable columns. To satisfy an order for a machine to mill complex aerospace aluminum parts, the Azkoitia, Spain, company incorporated an innovative new CNC that excels in 5-axis machining.
The control is the Series 30i from GE Fanuc Automation. It controls up to 40 axes, if required, and 24 simultaneously. Notable features include an ultrahigh-speed processor, high-speed internal bus, servo current control, and nanometer interpolation. Together, these features deliver 8 3 faster interpolation cycle times, 1,000-block look-ahead, and 0.4-msec block-processing times.
"Performance and functionality make the 30i ideal for our machines requiring multi-axis, multi-path, complex, and ultrahigh-speed features," says Koldo Arandia, general manager at Ibarmia.
Ibarmia's ZVH 55/L3000, the machine sporting the GE Fanuc Automation control, has an 8-mm rotary table with continuous movement integrated into the machine's bench. An open head lets users hydraulically clamp on the B axis at any angle. The machine delivers 25 kW of power for high-speed machining up to 9,000 rpm.
Along with the 30i control, the machine uses GE Fanuc Automation's 400-V HACH Alpha is Series servomotors for X, Y, and Z axes and for its rotary table. The control's hardware executes up to 10 different CNC programs simultaneously, and a built-in programmable-machine-control (PMC) sequence controller provides execution speeds of 25 ns/step for ladder programs — three of these programs can be executed at the same time.
