Our best estimate for the Nakamura-Tome JX-250 is $550,000 - $850,000. 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-jx-250#price; the request is passed to Nakamura-Tome or an authorised dealer.
The JX-250 turns 1,650 mm (65 in) long and 320 mm (12.6 in) in diameter, on chucks of 8 in and up, with a 4,500 rpm main spindle. The JX-200 is listed at 1,058 mm (41.7 in) of length, 6”, 8” chucks and a 6,000 rpm spindle. Pick the JX-250 for long and large parts, the JX-200 for faster spindle work on shorter ones.
The B-axis range is 240 degrees (+/-120 degrees). The table also lists an XY plane stroke of 250 mm square and Z crossover travel of R: 490 mm, L: 140 mm. The table does not explain these two rows further, so check them against a drawing of your part.
Standard is φ65 (A2-6), 65 mm (2.6 in) bar, 18.5/15 kW and 4,500 rpm. Bar capacity options are 71 mm (2.8 in), 80 mm (3.1 in) and 90 mm (3.5 in). The Ø80 mm option runs to 3,500 rpm; the Ø90 mm option runs to 2,500 rpm with an A2-8 nose and 22/18.5 kW, and turning length becomes 1,587 mm (62.5 in).
The ATC magazine holds 40 tools as standard, with 80 or 120 tools optional. For long parts with many features, the larger magazines avoid stopping to swap tools between jobs.
It measures 5,578.5 × 3,257.7 × 2,954 mm (W × D × H), with a machine height of 2,954 mm (116.3 in). Check crane hook height and door openings for delivery as well as floor space.
