How much does the Nakamura-Tome WT-200II 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 WT-200II is a two-turret, twin-spindle turn-mill center for bar work up to 65 mm, with a 260 mm maximum turning diameter and 400 mm of turning length on the main spindle. The table on this page has not been checked against a current Nakamura-Tome page, so the figures below are the listed ones and should be confirmed before purchase.
In the listed specification both turrets have 12 driven stations, and the upper turret has ±52.5 mm of Y-axis travel. Driven tools run to 6,000 rpm on 5.5 kW. With a driven tool in every position of both turrets, the machine can drill, tap and mill off-centre features while the other turret or spindle keeps working, which is the point of the layout.
The main spindle is listed at 5,000 rpm, 22 kW and 230 Nm; the sub-spindle at 5,000 rpm and 15 kW. Rapid traverse is given as 30 / 36 m/min on X and Z, and the control row reads NTControl. The 400 mm turning length is short next to the 780 mm (30.7 in) listed for the WT-300, so the WT-200II suits shorter bar parts rather than long shafts.

Strengths & Limitations
Strengths
- Two turrets with 12 driven stations each in the listed specification
- ±52.5 mm of Y-axis travel on the upper turret for off-centre features
- Main spindle listed at 22 kW and 230 Nm, with a 15 kW sub-spindle
- Both spindles listed at 5,000 rpm, with 65 mm bar capacity
Limitations
- The listed figures have not been confirmed against a current manufacturer page
- Y-axis travel is listed for the upper turret only
- Turning length is 400 mm on the main spindle, short for shaft work
- Driven tools are listed at 5.5 kW and 6,000 rpm, which limits heavy milling

Frequently Asked Questions
01
The listed specification gives 12 driven stations on the upper turret and 12 driven stations on the lower turret. Driven tools are listed at 6,000 rpm and 5.5 kW, and the upper turret has ±52.5 mm of Y-axis travel.
02
The main spindle is listed at 5,000 rpm, 22 kW and 230 Nm, with 65 mm bar capacity. The sub-spindle is listed at 5,000 rpm and 15 kW. Confirm these against the machine's own documentation, since this table has not been checked against a current manufacturer page.
03
The WT-300 lists 270 mm (10.6 in) of turning diameter and 780 mm (30.7 in) of turning length, with a 4,500 rpm spindle. The WT-200II is listed at 260 mm and 400 mm with 5,000 rpm, so it is the shorter, faster machine of the two.
04
The listed maximum turning diameter is 260 mm and the maximum turning length on the main spindle is 400 mm. Bar capacity is 65 mm. Larger or longer parts need a bigger machine, such as the WT-300 with 780 mm (30.7 in) of turning length.
