The Nexus QTN 450M is a high-torque, multitasking CNC turning center featuring a large-bore spindle. With a maximum swing of 33.3” and a maximum machining diameter of 22.8,” the machine is suited for larger-diameter workpieces. It features a 40-hp turning spindle with 1,327 foot-pounds of torque as well as a 12-station turret with a 10-hp, 4,000-rpm milling spindle (2,000 rpm optional). The integrated spindle/motor unit achieves speeds as fast as 2,000 rpm. The spindle bore is 6.5", and feeds are 1,181 ipm in the X and Z axes. According to the company, the machine’s design emphasizes rigidity in a construction that delivers machining capability while efficiently handling high turning and milling forces. The NC servo-driven tailstock features single-body construction that supports shaft workpieces and provides thrust force up to 2,923 lbs. The carriage and bed feature a new design promoting thermal stability, while the headstock also features chiller cooling for improved dimensional accuracy.
