The Quick Turn Nexus 450-II MY is the largest of the company’s Nexus series of turning and multitasking machines developed for the oil and gas services and construction machinery industries.
In addition to turning and milling, the machine also features boring capabilities for long, large-diameter shaft-type workpieces. Its combination tailstock, equipped with a bull-nose center and a 40" boring bar, enables deep-hole boring to depths ranging to 31.5". The machine’s headstock features a 7.2" through-bore size and a 50-hp integrated spindle motor that provides 2,000 rpm maximum speed. Optional 18" or 21" chuck sizes are available. Together with the Y-axis travel of a 12-position milling turret, the spindle is used as a C axis, capable of being indexed at 0.0001-degree increments to position workpieces for square-facing and slotting cuts, and off-center-line drilled holes.
Also on display will be the Orbitec 20 valve production center, which features a headstock spindle design and optional two-pallet changer.
