Our best estimate for the Nakamura-Tome NTY3-250 is $500,000 - $700,000. This is an estimate for a mill-turn / multi-tasking machines in this class, not a quote from Nakamura-Tome; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/nakamura-tome-nty3-250#price; the request is passed to Nakamura-Tome or an authorised dealer.
Because the turrets reach differently. The upper turret covers 310.5 mm (12.2 in) of turning length and the lower turret 905.5 mm (35.6 in). Long parts are therefore turned with the lower turret, and a cycle that needs the upper turret on a long part should be checked against the shorter reach.
The main spindle takes 65 mm (2.6 in) as standard, with options for 71 mm (2.8 in) and 80 mm (3.1 in). The right spindle takes 51 mm (2 in) as standard, with options for 65 mm (2.6 in) and 71 mm (2.8 in). Larger bores reduce speed: the Ø71 mm option runs to 3,500 rpm.
In speed and standard power, yes: both are 18.5 / 11 kW at 5,000 rpm. They differ in chuck and bar size. The left spindle has an 8 in chuck and 65 mm (2.6 in) bar, the right a 6 in chuck and 51 mm (2 in) bar. Only the left spindle lists a 26 / 22 kW option.
Both turn 225 mm (8.9 in) in diameter with three Y-axis turrets and up to 72 stations. The NTY3-150V runs faster, 6,000 rpm standard and a 10,000 RPM milling motor, on 51 mm (2 in) standard bar and 685 mm (27 in) of turning length. The NTY3-250 takes bigger bar, 65 mm (2.6 in) standard, at 5,000 rpm, and its lower turret reaches 905.5 mm (35.6 in).
The listed footprint is 4,900 × 2,580 × 2,395 mm (W × D × H). Add room for access, chip handling and any bar feeder when planning the installation, since the footprint figure covers the machine only.
