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 NT-Flex is a small twin-spindle turning center: Ø150 mm (5.9 in) of turning diameter, 405 mm (15.9 in) of turning length and 5 in chucks, with left and right spindles both running to 8,000 rpm on 7.5 / 5.5 kW. What it has in place of size is tooling. The turret row reads 24 per turret, 48 in total, and 96 with quad.

That ratio of tools to part size is the reason to look at this machine. Small turned parts such as fittings, valve components and pins often need many tools for a short cycle, and with 48 stations as standard several jobs can stay tooled up, cutting changeover time between short batches. The table does not explain the quad configuration, so ask Nakamura-Tome what it involves before planning on 96 tools.

Bar capacity is 32 mm (1.3 in) as standard and 38 mm (1.5 in) with the Ø38 mm option. At 8,000 rpm the spindles reach useful surface speed on these small diameters. The 7.5 / 5.5 kW rating is enough for that bar range but not for heavy cuts.

The machine is shallow front to back: 3,500 × 1,380 × 1,965 mm (W × D × H). For comparison, the NTJ-100 is listed at 175 mm (6.9 in) of turning diameter and 678 mm (26.7 in) of length with an 11 / 7.5 kW spindle at 5,000 rpm, so it takes larger parts but turns them more slowly.

Strengths & Limitations

Strengths

24 tool stations per turret, 48 in total, and 96 with quad
Left and right spindles both run to 8,000 rpm for small diameters
Compact 3,500 × 1,380 × 1,965 mm (W × D × H) frame
Bar capacity of 32 mm (1.3 in), or 38 mm (1.5 in) with the option

Limitations

Turning diameter is limited to Ø150 mm (5.9 in) and length to 405 mm (15.9 in)
7.5 / 5.5 kW per spindle rules out heavy roughing
Only 5 in chucks are listed, so chucked blanks must be small
The table does not define the quad configuration needed for 96 tools

Best For

Small bar parts up to 32 mm (1.3 in), or 38 mm (1.5 in) with the option High-mix work that keeps 48 tools loaded Small diameters that need 8,000 rpm on both spindles Cells where floor depth is limited to about 1,380 mm

Frequently Asked Questions

01 How many tools does the NT-Flex hold?

The table lists 24 tools per turret, 48 in total, and 96 with quad. It does not describe the quad configuration, so confirm with Nakamura-Tome what is needed to reach 96 before relying on that figure.

02 What size parts can the NT-Flex machine?

Up to Ø150 mm (5.9 in) in diameter and 405 mm (15.9 in) in length, on 5 in chucks. Bar capacity is 32 mm (1.3 in), or 38 mm (1.5 in) with the Ø38 mm option.

03 How does the NT-Flex compare with the NTJ-100?

The NTJ-100 is listed at 175 mm (6.9 in) of turning diameter and 678 mm (26.7 in) of length, with an 11 / 7.5 kW spindle at 5,000 rpm and a 6 in chuck. The NT-Flex is smaller, turns faster at 8,000 rpm on 7.5 / 5.5 kW, and lists 48 tools across its turrets.

04 How much floor space does the NT-Flex need?

It measures 3,500 × 1,380 × 1,965 mm (W × D × H). The 1,380 mm depth lets it fit in tight cells, but add the length of a bar feeder and space for chip handling when planning the layout.
