Profiler Sets Titanium Machining Record
Fives' new 5-axis Cincinnati XT Profiler sets metal removal record by machining titanium at 100+ cu ipm, an unmatched throughput on a single-machine platform that promises aerospace manufacturers an industry-best performance/investment payoff.
The new 5-Axis Cincinnati XT “super profiler” from Fives (Hebron, KY) has broken the “sound barrier” in aerospace titanium machining by demonstrating a 100 cu ipm metal removal rate (MRR) during test cutting prior to customer shipment.
According to Chip Storie, the executive vice president of Fives Cincinnati, the 5-axis, 5-spindle XT profiler is engineered and built for maximum dynamic stiffness and sustained power in titanium roughing operations to meet the industry’s need for maximum throughput and investment return.
“The industry needs to set new standards for producing titanium parts at the lowest cost per piece, and the XT Profiler provides that capability and more,” he emphasized. “This machine is in a performance class by itself, equipped with a massive cross rail and robust spindle design that enable it to perform at this high rate on a sustained basis. We expect to exceed 100 cu ipm metal removal once the machine is married to its dedicated foundation and high-pressure coolant system. This demonstration is only the beginning, and is going to change the way the industry approaches titanium machining.”
Randy Von Moll, the director of technical sales, 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 and it was a remarkable demonstration that exceeded our highest expectations.”
The new 5-axis gantry design utilizes the same high-stiffness frame as the previously introduced 3-axis XT model. “The 3-axis version of this machine really proved itself, and the new 5-axis version builds on the success of the platform,” noted Von Moll. “We set demanding requirements for the 5-axis model, and our engineers stepped up with a completely new approach that is superior to anything else on the market. This is a major breakthrough in gantry design that gives our customers significant new capabilities. Accuracy will be on par with the 3-axis design. The A/B rotary axes on each spindle can be independently calibrated and controlled to enhance accuracy.”
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 rpm to 7,000 rpm. The alternative high-torque spindle with HSK 125A tool interface is rated 51 kW (68 hp) and produces 2,523 Nm (1,860 ft-lb) S1 torque with a maximum speed of 3,500 rpm.
“A multispindle machine that can rough and finish titanium at this rate provides our customers with a strategic advantage,” explained Von Moll. “A single-spindle machine runs at roughly the same speeds and feeds, yet our machines complete five parts in the same cycle time, so we are much more efficient and the result for our customer is a much better return on investment with lower risk.”
The XT models build upon the most popular multi-spindle machining platform in the aerospace industry with more installations than all other builders combined. This experience base and the new performance parameters result in a new era for manufacturers of aerospace titanium components.
