Our best estimate for the Nakamura-Tome NTRX-300L is $450,000 - $650,000. 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-ntrx-300l#price; the request is passed to Nakamura-Tome or an authorised dealer.
Turning length and width. The NTRX-300L turns 1,600 mm (63 in) long and is 5,440 mm wide. The NTRX-300 turns 1,100 mm (43.3 in) long and is 4,529 mm wide. Both are listed at 640 mm (25.2 in) of turning diameter and a 4,500 rpm main spindle.
An optional magazine for 3 long tools, listed at 65mm x 450mm. It is meant for deep bores and long holes that a standard holder cannot reach, which are common on the long parts this machine is built for.
The ATC magazine holds 40 tools as standard, with 60, 80 or 120 optional, plus the optional long-tool ATC for 3 tools. The B-axis swivels through 240 deg (+/-120 deg).
The L spindle runs to 4,500 rpm on 15/11 kW, with 22/18.5 kW optional; larger bore options lower it to 3,500 rpm or 2,500 rpm. The R spindle runs to 2,500 rpm, so plan small-diameter finishing on the L side.
