Our best estimate for the Mazak Quick Turn Nexus 450MY is $340,000 – $520,000. 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-my#price; the request is passed to Yamazaki Mazak or an authorised dealer.
The table is not consistent on this. One row lists a maximum turning length of 1,524 mm (60 in) with 1,570 mm (61.8 in) of Z travel; the rows for the QUICK TURN 450MY-80 list a machining length of 80.31 in. Treat the bed length as unknown until it has been measured or read from the machine's documents.
It is not in Mazak's current lineup under the Nexus name. Mazak's table for the present Quick Turn 450MY gives an 18 in chuck, 2,000 rpm, Ø24 in (610 mm) of turning diameter, 80 in (2,032 mm) of turning length and 8 in (203 mm) of Y travel. The listed Nexus machine is similar in size, but the tables should not be mixed.
37 kW (50 hp) at 25% ED and 22 kW (30 hp) continuous, with 2,450 Nm (1,807 ft-lb) of torque at 25% ED and a 2,000 RPM maximum on an A2-11 nose. For long roughing cuts plan with the continuous figure. The milling spindle is listed at 4,500 RPM with no power figure.
The listed Y-axis is ±80 mm (±3.15 in). On long shafts that allows keyways, wrench flats and offset holes to be cut while the part is still held between chuck and tailstock, which saves moving a heavy part to a second machine.
The Quick Turn Nexus 550-II is listed as a larger machine without the 450MY's Y-axis rows: 830 mm (32.68 in) of turning diameter, a 610 mm (24 in) chuck, 1,500 RPM, 4,800 Nm (3,540 ft-lb) at 25% ED and 22,000 kg (48,502 lb). The 450MY is listed at 14,500 kg (31,967 lb) with a 2,000 RPM spindle.
