How much does the Nomura NN-38 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-38 is listed as a 38 mm (1.496 in) Swiss-type lathe with 9-axis simultaneous control, including a Y axis on both the main and sub spindle sides and a B axis. Nomura's current product pages do not show a model under this name; the maker has not confirmed the table, and the numbers below are the listed figures.
The second Y axis is the reason to look at this machine over the NN-32, which is listed with Y on the main spindle side only and 7-axis control. With Y2 at the sub spindle, off-centre drilling and milling can be done on the back of the part as well as the front, and the B1 axis is there for angled holes and faces. Up to 32 tool positions are listed.
The larger bar brings lower speeds and more power. Main and sub spindles both run to 6,000 RPM, as do the driven tools, with 11 kW (14.7 hp) on the main spindle and 5.5 kW (7.4 hp) on the sub. The NN-32 is listed at 8,000 RPM with 7.5 kW (10 hp) and 3.7 kW (5 hp). For 38 mm bar the extra power is the useful trade, while small-diameter features will cut at a lower surface speed than on the smaller machine.
Machining length is 230 mm (9.06 in) through the guide bushing. Listed spindle runout is below 0.003 mm, positioning accuracy ±0.003 mm and repeatability ±0.002 mm. At 4,200 kg (9,259 lb), floor loading and rigging need more allowance than a lighter sliding-head machine would.

Strengths & Limitations
Strengths
- Y axis on both the main and sub spindle sides, plus a B axis, under 9-axis simultaneous control
- 11 kW (14.7 hp) main spindle and 5.5 kW (7.4 hp) sub spindle
- Bar capacity of 38 mm (1.496 in) with 230 mm (9.06 in) of machining length
- Up to 32 tool positions with driven tools at 6,000 RPM
Limitations
- Spindles and driven tools top out at 6,000 RPM, which holds back small drills and end mills
- Listed positioning accuracy is ±0.003 mm and repeatability ±0.002 mm, looser than the ±0.002 mm and ±0.001 mm listed for the NN-32
- Weighs 4,200 kg (9,259 lb), against 3,000 kg (6,614 lb) for the NN-32

Frequently Asked Questions
01
The table lists X1, Z1, Y1, X2, Z2, Y2, C1, C2 and B1 under 9-axis simultaneous control. In practice that is a C axis on both spindles, a Y axis on both the main and sub spindle sides, and one B axis.
02
The NN-38 is listed at 6,000 RPM on both spindles with 11 kW (14.7 hp) and 5.5 kW (7.4 hp). The NN-32 is listed at 8,000 RPM with 7.5 kW (10 hp) and 3.7 kW (5 hp). The larger machine has the power, the smaller one the speed.
03
Maximum bar capacity is listed as 38 mm (1.496 in) and maximum machining length as 230 mm (9.06 in). The machine works through a guide bushing, described in the table as a precision Nomura design.
04
The listed figures are spindle runout below 0.003 mm, positioning accuracy of ±0.003 mm and repeatability of ±0.002 mm. None of these has been confirmed by the maker, so ask for measured results on the machine being offered.
