Profiler sets metal removal rate record
MAG’s XTi profiler demonstrated a 90-cubic-inch-per-minute metal removal rate (MRR) in titanium prior to shipment to Aerospace Dynamics International Inc. (ADI), Valencia, Calif. The machines are part of a $100 million expansion that includes a new 120,000-sq-ft manufacturing center. The two machines will share a 120-foot X-axis rail for multi-part production of titanium components for the Boeing 777 and 787, and Airbus A350.
The XTi profiler uses five spindle motors capable of up to 3500 rpm, each rated 51 kW (68 hp) and producing 2523 Nm (1860 ft lb) of torque. The machine is engineered with a new spindle support structure that is incorporated into an extremely stiff, heavyweight gantry for superior damping. The massive cross rail is 77 percent larger than previous designs, providing added stiffness, rigidity and damping for high-horsepower, chatter-free machining. The XTi is available with HSK 125A tool interface as an option. Five 6-pocket tool exchangers, located at each end of the work zone, permit five tool exchanges per machine. X-axis motion is powered by rack-and-pinion drives on both rails, while Y and Z axes are driven by large-diameter ballscrews, with a counterbalance and brake on the Z. The two new 5-spindle XTi profilers join 32 other mostly MAG profilers at ADI.
