The Haas UMC-750SS is a Super Speed 5-axis vertical machining center with a reputation for dependable 5-axis productivity that has made it a staple in aerospace, medical, and high-mix job shop environments. This 2016 unit delivers travels of 30" × 20" × 20" through a 15,000 RPM inline direct-drive CAT 40 spindle driven by a 30 HP motor, with rapids to 1,417 ipm, a 40-pocket side-mount tool changer, and an integrated dual-axis trunnion table offering full 4th-axis continuous rotation for true 5-sided machining. The machine comes factory-equipped with through-spindle coolant, a programmable coolant nozzle, auxiliary coolant filtration, a Haas CC-E4 belt-type chip conveyor, high-speed machining, expanded memory, an ethernet interface, Haas Connect remote monitoring, a remote jog handle, and rigid tapping, and it ships with a Makro-Grip 125 5-axis vise, Quick-Point pallet plates, a hard-coated aluminum sub-base, and a 59-piece tooling package.
Compared to the earlier standard Haas UMC-750, the UMC-750SS Super Speed delivers a meaningful performance upgrade. Haas replaced the UMC-750's 8,100 RPM 40-taper spindle with a 15,000 RPM inline direct-drive head, pushed rapids from roughly 1,000 ipm up to 1,417 ipm, and made high-speed machining and expanded control memory standard — directly shortening cycle times on aluminum aerospace and contoured medical parts. For shops looking to step beyond the entry UMC-750 without jumping to a European 5-axis price point, the UMC-750SS is the right upgrade at a used-machine price.
