2022 Haas UMC-750SS CNC Vertical Mill

The 2022 Haas UMC-750SS is a CAT-40 super-speed vertical machining centre that drives 30-in X, 16-in Y and 20-in Z strokes at 1 200 inch-per-minute rapids across a 36- by 18-inch table, yet its TR-160 trunnion tilts 120 degrees and spins 360 degrees to cradle parts up to 660 lb on a 19.7-inch platter. A 30 HP inline motor launches cutters to 15 000 RPM and delivers 90 ft-lb torque for steel hog-outs, all cooled by 1 000 PSI through-spindle coolant that drills Inconel without peck-cycles. Haas Next-Gen Control layers Dynamic Work Offsets, Tool Centre-Point Control and High-Speed Machining over WIPS probing, letting operators probe, align and cut complex blisks in a single chucking. A 50 + 1 side-mount changer flips tools in 2.8 seconds chip-to-chip and a chip auger funnels swarf out the rear for lights-out shifts.

Against the UMC-750—limited to 12 000 RPM and 40 + 1 tools—the SS variant adds 3 000 RPM, boosts ATC capacity to 50 + 1, and equips the high-speed trunnion with 150 deg/sec rotary rapids, all while retaining identical work envelope and Haas macros ? ?. That means legacy programs port over instantly but finish hours sooner, giving the SS the edge for aerospace ribs and medical implants where cycle time equals profit.
