The 5-Axis Cincinnati XT “super profiler” has broken the “sound barrier” in aerospace titanium machining by demonstrating a 100-in.3 per min metal removal rate (MRR) during test cutting prior to customer shipment.
According to Chip Storie, Fives Cincinnati executive vice president, the 5-axis, 5-spindle XT profiler is engineered and built for maximum dynamic stiffness and sustained power in titanium roughing operations.
This machine is equipped with a massive cross rail and spindle design for sustained operation. Storie expects it to exceed the 100 -in.3 per min metal removal once the machine is married to its dedicated foundation and high-pressure coolant system.
Director of Technical Sales Randy Von Moll added: “This is the stiffest 5-axis profiler we’ve ever seen in action, able to make these demanding cuts in titanium with ease. The machine peeled off perfect ‘6-shaped’ chips with no chatter or sign of structural instability. The part finish was excellent.”
The gantries have a 3.8 m (145 in.) Y-axis range, with a Z-axis travel of 711 mm (28 in.). Each spindle’s angular A and B axes can travel ±30 degrees. The machine tested is equipped with five 52 kW (70 hp) spindles, and each spindle can deliver up to 1,345 Nm (986 ft lb) torque into the cut at 40-7,000 rpm. The alternative high-torque spindle with HSK 125A tool interface is rated 51 kW (68 hp) and produces 2,523 Nm (1860 ft lb) S1 torque with a maximum speed of 3,500 rpm.
