How much does the Nakamura-Tome NTR Series cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Nakamura-Tome. Configuration moves it a long way.
Overview
The Nakamura-Tome NTR Series is listed here as a sliding-headstock (Swiss-type) lathe for bar up to 32 mm (1.26 in), with a hydrodynamic guide bushing, main and counter spindles at 8,000 RPM and up to 40 total tool positions. This table has not been checked against a current Nakamura-Tome page, so treat the listed figures as a starting point and confirm them for the specific machine.
The listed maximum machining length is 200 mm (7.87 in) per cycle, which is the stroke a guide-bushing machine works within before it re-chucks the bar. Parts longer than that are still possible but take more than one stroke. A bushing-less option is listed as available, which suits short parts where bar remnant matters more than support.
Power is modest, as is usual for this class: 3.7 kW (5 hp) on the main spindle and 2.2 kW (3 hp) on the counter spindle, with live tools listed at 6,000 RPM. The cross-slide axes are listed as X1, Z1, X2, Z2 and Y1, and rapid traverse as 32 m/min (1,260 ipm). Approximate machine weight is 2,500 kg (5,512 lb), which matters for floor loading and rigging.

Strengths & Limitations
Strengths
- Takes bar up to 32 mm (1.26 in) through a hydrodynamic guide bushing
- Up to 40 total tool positions on multiple cross-slide axes
- Main and counter spindles both listed at 8,000 RPM
- Bushing-less option listed for short parts
Limitations
- The listed figures have not been confirmed against a current manufacturer page
- Main spindle power of 3.7 kW (5 hp) limits heavy cuts on the largest bar
- Machining length is 200 mm (7.87 in) per cycle, so longer parts need re-chucking
- Live tools are listed at 6,000 RPM, slow for very small cutters

Frequently Asked Questions
01
The listed maximum bar capacity is 32 mm (1.26 in), with a maximum machining diameter of 32 mm (1.26 in). Machining length is listed as 200 mm (7.87 in) per cycle.
02
The listed specification is a hydrodynamic guide bushing, with a bushing-less option available. The guide bushing supports long slender work close to the tool; running without it suits short parts and reduces bar remnant.
03
The main spindle is listed at 8,000 RPM and 3.7 kW (5 hp), the counter spindle at 8,000 RPM and 2.2 kW (3 hp). Live tools are listed at 6,000 RPM. Confirm these against the machine's own documentation before quoting work on them.
04
Approximately 2,500 kg (5,512 lb) in the listed specification. Check floor loading and rigging access on that figure, and confirm it for the exact model in the series being considered.
