How much does the Nakamura-Tome NTX-C cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Nakamura-Tome. Configuration moves it a long way.
Overview
The Nakamura-Tome NTX-C is listed as a small B-axis turn-mill center: 38 mm (1.5 in) bar capacity, 120 mm (4.72 in) of turning diameter and 300 mm (11.81 in) of turning length, with a main and a counter spindle both running to 8,000 RPM. This model does not appear on Nakamura-Tome's current product pages, so treat the listed figures as a guide and check them on the machine you are offered.
The main spindle is rated 11 kW (15 HP), and C-axis is listed on both spindles. Milling is done by a B-axis milling spindle that swivels +/- 120 deg, rated 5.5 kW (7.4 HP) and running to 10,000 RPM, supported by a 16-station lower turret. Y-axis travel is 80 mm (+/- 40 mm), X-axis travel 125 mm (4.92 in) and Z-axis travel 300 mm (11.81 in), with rapid traverse of 30 m/min (1,181 ipm).
The envelope is small and the machine is not light: the listed weight is 5,000 kg approx. That is a lot of machine for a 120 mm (4.72 in) part, so check floor loading and rigging before delivery. The work it is built for is small bar parts with milled and drilled features on both ends, machined complete.
