Demand for the American-made Quick Turn Nexus 450-II MY multi-tasking machine, the largest model in Mazak’s Nexus series of turning and multi-tasking machines, continues to grow, says the company and is especially suitable for the oil and gas and construction machinery industries.
Mazak currently produces more than 100 different models of turning centres, multi-tasking machines, and vertical machining centres, many of which include five axis machining capabilities. The company incorporates modular assembly operations in its US manufacturing plant as part of its “Production-On-Demand” manufacturing principle, as well as using an extensive amount of Mazak multi-tasking technology and unattended machining operations.
The 450-II MY showcases not only turning and milling, but also boring capabilities for long, large diameter shaft-type workpieces. The machine?s special combination tailstock, equipped with a bull nose center and a 1016 mm (40 in.) boring bar, allows for deep-hole boring to depths of up to 800 mm (31.5 in.).
The machine?s headstock features a 183 mm (7.2 in.) through-bore size and a 50 hp integrated spindle motor that provides a maximum speed of 2,000 rpm. Optional 457 mm (18 in.) or 533 mm (21 in.) 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° increments to accurately position workpieces for square facing and slotting cuts or off-center-line drilled holes.
