How much does the Nakamura-Tome TW-10 cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Nakamura-Tome. Configuration moves it a long way.
Overview
The Nakamura-Tome TW-10 is, in the listed figures, a small two-spindle turning center: a 210 mm (8 in) main chuck and a 165 mm (6.5 in) sub chuck, 51 mm (2 in) bar capacity, 230 mm turning diameter and 400 mm turning length. Both spindles run to 6,000 rpm; the main spindle is rated 18.5 kW and the sub-spindle 11 kW.
The power split shows how the work divides. The main spindle carries the first operation, where most of the stock comes off, while the sub-spindle at 11 kW takes the part after cut-off for back facing, drilling and finishing. The main turret has 12 stations, and live tooling runs to 5,000 rpm, so cross holes and flats can be added in the same cycle. The control is listed as NT Smart X.
The envelope is close to that of the SC-100, which also lists 230 mm (9.1 in) of turning diameter and 400 mm (15.7 in) of turning length but an 11 / 7.5 kW main spindle at 5,000 rpm. The TW-10 listing is stronger on paper at 18.5 kW and 6,000 rpm. Ask Nakamura-Tome for a current specification sheet before relying on these figures, and on a used machine check them against the nameplate and the turret actually fitted.

Strengths & Limitations
Strengths
- Main and sub-spindle both run to 6,000 rpm
- 18.5 kW main spindle for the first operation, with an 11 kW sub-spindle for back-working
- 12-station main turret with live tooling to 5,000 rpm
- Separate chuck sizes: 210 mm (8 in) main and 165 mm (6.5 in) sub
Limitations
- Sub-spindle is rated 11 kW, so heavy cuts belong on the main spindle
- Bar capacity is 51 mm (2 in), which keeps larger bar off the machine
- Turning diameter of 230 mm and turning length of 400 mm restrict it to small parts
- The table lists no Y-axis travel or live-tool power

Frequently Asked Questions
01
Two. The main spindle is listed at 18.5 kW and 6,000 rpm with a 210 mm (8 in) chuck and 51 mm (2 in) bar capacity. The sub-spindle is listed at 11 kW and 6,000 rpm with a 165 mm (6.5 in) chuck.
02
The main turret is listed with 12 stations, and live tooling runs to 5,000 rpm. The table gives no live-tool power or Y-axis travel, so check those on the specific machine if milled features are part of the work.
03
The SC-100 lists 230 mm (9.1 in) of turning diameter and 400 mm (15.7 in) of turning length with an 11 / 7.5 kW main spindle at 5,000 rpm. The TW-10 listing has the same 230 mm and 400 mm envelope with an 18.5 kW main spindle at 6,000 rpm.
04
The listed maximum chuck diameter is 210 mm (8 in) on the main spindle and 165 mm (6.5 in) on the sub-spindle. Bar capacity is 51 mm (2 in), so most work will be bar-fed small parts.
