Overview
The Nakamura-Tome NEW TW-30 is a two-spindle turning center for large chucked parts: left and right spindles each rated 22/18.5kW at 3,500 rpm, a 10 in chuck as standard, 335 mm (13.2 in) of turning diameter and 300 mm (11.8 in) of turning length.
What sets it apart is that the right spindle is not a smaller helper. The table lists the same 22/18.5kW drive motor on both sides, so the second side of a part can be cut with the same depth and feed as the first. Compare the AS-200L, whose optional right spindle is rated 7.5 / 5.5 kW against 15 / 11 kW on its main spindle. On the NEW TW-30, a part with heavy features on both faces does not have to be planned around a weak second operation, and the two operations can be balanced for cycle time.
Chuck choice is broad. Beyond the standard 10 in chuck, the table lists 12 in and 15 in chucks as options, and bar capacity is 71 mm (2.8 in). The short 300 mm turning length combined with a 15 in chuck option points at flanges, hubs, gear blanks and other wide, short parts rather than shafts. Keep in mind that a larger chuck usually carries a lower permitted speed than the spindle's 3,500 rpm.
The table lists 24 tool stations, described as expandable, but gives no turret count, Y-axis travel or driven-tool rating, so ask for the tooling layout if milling is part of the job. The machine is large for its turning envelope at 4,975 × 2,606.3 × 2,250 mm (W × D × H); plan the floor before anything else.

Strengths & Limitations
Strengths
- Left and right spindles are both rated 22/18.5kW at 3,500 rpm, so the second operation has the same power as the first
- 10 in chuck standard, with 12 in and 15 in chucks listed as options
- 24 tool stations, listed as expandable
- 335 mm (13.2 in) turning diameter, larger than the 290 mm (11.4 in) of the AS-200
- 71 mm (2.8 in) bar capacity for bar-fed work alongside chucked parts
Limitations
- Turning length is 300 mm (11.8 in), so long shafts are outside its range
- Both spindles top out at 3,500 rpm, which is slow for small diameters
- Footprint of 4,975 × 2,606.3 × 2,250 mm (W × D × H) is large for the turning envelope
- The table lists no Y-axis or driven-tool figures, so milling capability has to be confirmed before ordering

Frequently Asked Questions
01
Both are listed at 22/18.5kW and 3,500 rpm. Because the right spindle matches the left, the second side of a part can be roughed as hard as the first, which makes it easier to balance the two operations.
02
A 10 in chuck is standard, and the table lists 12 in and 15 in chucks as options. A larger chuck holds wider parts but usually has a lower speed rating, so check the chuck's limit against the 3,500 rpm spindles.
03
The table lists 24 tool stations and describes them as expandable. It gives no turret count, Y-axis travel or driven-tool rating, so ask Nakamura-Tome for the tooling layout if parts need milled features.
04
The SC-300II swings 360 mm (14.2 in), turns up to 635 mm (25 in) long and lists a ±60 mm (±2.36 in) Y-axis, with a 22 / 18.5 kW spindle at 3,500 rpm. The NEW TW-30 is shorter at 300 mm (11.8 in) but offers a 15 in chuck option and a matched 22/18.5kW right spindle.
05
The footprint is 4,975 × 2,606.3 × 2,250 mm (W × D × H). Allow extra room for a bar feeder if you plan to run 71 mm (2.8 in) bar, and for chip conveyor and service access.
