Att 1 - CNC 5 Axis milling center salient characteristics Rev 2 14Jul26.pdf

This document is a Salient Characteristics memorandum issued by the Department of the Air Force, 97th Air Mobility Wing (AETC) at Altus Air Force Base, Oklahoma, dated 14 July 2026. The memorandum outlines detailed specifications for a required 5-Axis Vertical Machining Center with a 30" x 20" x 20" work envelope and integrated 2-axis trunnion rotary table. The machine must feature a 40-taper spindle with 30 horsepower (22.4 kW) vector drive capable of 12,000 rpm and 90 foot-pounds of torque at 2,000 rpm, with electronic thermal compensation for each linear axis, 1200 IPM rapid rates, and 650 IPM maximum cutting speed. The equipment requires a 30+1 side-mount tool changer, wireless intuitive probing system, and a maximum footprint of 158.0" width by 124.1" depth by 123.2" height.

The machine must include a 55-gallon flood coolant system with auxiliary coolant filter, maintenance package, and sanitizer, along with through-tool air blast and through-spindle coolant capabilities. Additional mandatory features include a transferable controller compatible with other CNC machining centers, belt-type chip conveyor, top cover with mist extraction provision, programmable coolant nozzle, broken tool detection, high-speed machining capability, and automatic door. The B-Axis tilt range must accommodate +120/-35 degrees with C-Axis 360-degree rotation capability.
