How much does the Nomura NN-32 cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Nomura. Configuration moves it a long way.
Overview
The Nomura NN-32 is listed as a 32 mm (1.260 in) Swiss-type lathe with main and sub spindles that both run to 8,000 RPM, a guide bushing and 220 mm (8.66 in) of machining length. Nomura's current product pages do not show a model under this name, so the table is unconfirmed by the maker and is given here as the listed figures.
The axis layout defines what it can finish in one cycle. The table describes 7-axis simultaneous control with a C axis on both the main and sub spindle, but the Y axis is on the main spindle side only. With no Y axis on the sub spindle side, off-centre features on the back end have to rely on C-axis positioning. The NN-38 adds a second Y axis and a B axis, and gives up speed for it: its spindles and driven tools are listed at 6,000 RPM.
Power is split 7.5 kW (10 hp) on the main spindle and 3.7 kW (5 hp) on the sub spindle, so heavy stock removal belongs on the main side while the sub spindle handles pickup and finishing. Driven tools reach 8,000 RPM, the same ceiling as the spindles, and up to 28 tool positions are listed.
The precision rows are tight for this bar size: spindle runout below 0.002 mm, positioning accuracy of ±0.002 mm and repeatability of ±0.001 mm. Treat those as values to prove at acceptance. Machine weight is 3,000 kg (6,614 lb).

Strengths & Limitations
Strengths
- Main and sub spindle both listed at 8,000 RPM, with driven tools at 8,000 RPM as well
- C axis on both the main and sub spindle under 7-axis simultaneous control
- Up to 28 tool positions are listed across the two spindles
- Listed positioning accuracy of ±0.002 mm and repeatability of ±0.001 mm
- 220 mm (8.66 in) of machining length through the guide bushing
Limitations
- The Y axis is on the main spindle side only, which limits off-centre work on the back of the part
- Sub spindle power is 3.7 kW (5 hp), half the main spindle's 7.5 kW (10 hp)
- Bar capacity is 32 mm (1.260 in); the NN-38 is listed at 38 mm (1.496 in)

Frequently Asked Questions
01
On the listed figures the NN-32 takes 32 mm (1.260 in) bar and has 7-axis control with Y on the main spindle side only. The NN-38 takes 38 mm (1.496 in) bar and has 9-axis control with Y on both sides. The NN-32 spindles run to 8,000 RPM; the NN-38 spindles are listed at 6,000 RPM.
02
No. The table lists the Y axis on the main spindle side. Both spindles have a C axis, so the sub spindle can index and contour around its centreline, but off-centre milling on the back end is not supported by a Y axis.
03
The main spindle is listed at 7.5 kW (10 hp) and the sub spindle at 3.7 kW (5 hp). Both run to 8,000 RPM, and the driven tools are listed at 8,000 RPM too.
04
Spindle runout below 0.002 mm, positioning accuracy of ±0.002 mm and repeatability of ±0.001 mm. They are the listed figures and have not been confirmed by the maker, so ask for an inspection report or a test part.
