Our best estimate for the Mazak Quick Turn Nexus 450-II is $280,000 – $420,000. This is an estimate for a cnc lathes / turning centers in this class, not a quote from Yamazaki Mazak; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/mazak-quick-turn-nexus-450-ii#price; the request is passed to Yamazaki Mazak or an authorised dealer.
No, it is not in Mazak's current lineup. The Quick Turn 450MY in the present range has an 18 in chuck, a 2,000 rpm spindle and Ø24 in (610 mm) of turning diameter, and adds milling and a Y-axis that the listed Nexus 450-II table does not show.
The table lists 2,450 Nm (1,807 ft-lb) of torque at 25% ED, and power of 37 kW (50 hp) at 25% ED or 22 kW (30 hp) continuous, with a 2,000 RPM maximum. Use the continuous figure for long roughing passes and the 25% ED figures for short heavy cuts.
The Quick Turn Nexus 550-II is the bigger machine: 830 mm (32.68 in) of turning diameter, 1,800 mm (70.87 in) of turning length, 4,800 Nm (3,540 ft-lb) at 25% ED, 1,500 RPM and 22,000 kg (48,502 lb). The 450-II is listed at 600 mm (23.62 in), 1,524 mm (60 in), 2,450 Nm (1,807 ft-lb) at 25% ED, 2,000 RPM and 12,500 kg (27,558 lb).
Not according to the listed table, which has a turret of 12 positions and no milling spindle or Y-axis row. The Quick Turn Nexus 450MY is the listed variant with a milling spindle of 4,500 RPM and a Y-axis of ±80 mm (±3.15 in).
The chuck actually fitted, since the table lists 533 mm (21 in), and the spindle bore against the listed 102 mm (4 in) bar capacity. Also confirm the control, listed as MAZATROL SmoothG CNC, and plan the move around the listed 12,500 kg (27,558 lb).
