Our best estimate for the Mazak Quick Turn Nexus 550-II is $420,000 – $620,000. 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-550-ii#price; the request is passed to Yamazaki Mazak or an authorised dealer.
No, it is not in Mazak's current lineup. Anyone considering one is looking at an existing machine, so the figures that matter are those on its own plate and in its manual. The listed figures on this page are a starting point for that check.
The listed figures are a 610 mm (24 in) chuck, 1,800 mm (70.87 in) of maximum turning length, a 46.33" swing over the bed and a 12.5" bar capacity. X travel is listed at 475 mm (18.7 in) and Z travel at 1,855 mm (73.0 in).
4,800 Nm (3,540 ft-lb) at 25% ED, on an A2-15 spindle nose. That is an intermittent rating. The Quick Turn Nexus 450MY is listed at 2,450 Nm (1,807 ft-lb) at 25% ED, so on the same rating the 550-II has close to twice the torque.
Start with the points where the listed rows disagree: top spindle speed, motor power, maximum turning diameter and the control fitted. Then check the tooling, since the turret is listed as a 12-position VDI 80 type, and the site, since the listed weight is 22,000 kg (48,502 lb).
