Overview
The Tsugami B032-III is a 32mm-class opposed gang tool Swiss-type CNC lathe in Tsugami's third-generation B-series, covering sub-variants B0325B (5-axis) and B0326 (6-axis). At 32 mm (1.26 in) bar capacity, this machine handles a wide range of parts that the more common 20mm Swiss lathes can't accommodate -- larger orthopedic components, hydraulic fittings, automotive shafts, and industrial fasteners that demand Swiss-level precision.
The specs reflect the larger bar capacity: 200-8,000 RPM main and sub-spindle speeds (lower than the 20mm machines due to the larger workpiece diameter), 3.7/5.5 kW spindle motor, and live tooling at 6,000 RPM. The 5-axis B0325B offers 31/32 tool positions with 4/8 live stations, while the 6-axis B0326 steps up to 32/42 total positions with 15/26 live stations. That's a serious amount of tooling capacity, especially on the 6-axis version.
The guide bushing is convertible between Swiss and chucker modes, with headstock stroke reaching 330 mm (12.99 in) -- enough for long shafts and pins that are common in the 32mm part class. Rapid traverse runs at 35 m/min. The 5-axis variant uses the FANUC 0i-TF Plus control, while the 6-axis B0326 gets the FANUC 32i-B for Y-axis coordination.
At 4,000 kg (8,818 lbs) and 2,628 x 1,280 x 1,970 mm (103.5 x 50.4 x 77.5 in), the B032-III is a substantial machine. It competes against the Citizen A32, Star SV-32, and Tornos SwissNano 7 in the 32mm class. Tsugami's opposed gang tool approach provides fast tool-to-tool times that keep cycle times competitive despite the machine's size.

Strengths & Limitations
Strengths
- 32mm bar capacity handles a wide range of larger precision parts that 20mm machines can't accommodate
- 330mm headstock stroke is generous for long shafts and pins common in the 32mm part class
- 6-axis B0326 variant offers up to 42 tool positions with 26 live stations -- massive tooling capacity
- 3.7/5.5 kW spindle motor provides real cutting power for stainless, titanium, and high-temp alloys
- 35 m/min rapid traverse keeps positioning moves fast despite the machine's larger size
- Convertible guide bushing covers both long Swiss parts and short chucker parts
Limitations
- 8,000 RPM max spindle speed is lower than the 10,000 RPM available on 20mm machines, affecting cycle time on smaller diameter features
- 4,000 kg weight requires solid floor loading and limits easy relocation
- 6,000 RPM live tooling is slower than the 10,000 RPM offered on the S-series 20mm machines
- Larger footprint at 2,628mm wide demands more floor space than the 20mm class

Frequently Asked Questions
01
The B0325B is suitable for parts with on-center features only -- turning, center drilling, and threading. If your parts need off-center holes, flats, hex profiles, or milling operations, the B0326's Y-axis is essential. The B0326 also offers significantly more tooling capacity (42 vs. 32 positions) and more live tool stations (26 vs. 8), making it better for complex, multi-feature parts.
02
Both are competitive 32mm Swiss machines. The Citizen A32 offers LFV chip-breaking technology as an option, which is valuable for stringy materials. The Tsugami B032-III counters with its opposed gang tool design for faster tool changes and the B0326's 42 tool positions. Service and support networks vary by region, which is often the deciding factor.
03
Larger bar diameter means larger workpiece mass spinning at high speed. At 32mm bar capacity, 8,000 RPM already generates significant centrifugal forces and surface speeds. For a 32mm bar at 8,000 RPM, the surface speed is approximately 800 m/min, which exceeds cutting speed requirements for most materials. The speed is optimized for the diameter range.
04
The 6-axis B0326 typically runs $40,000-$80,000 more than the 5-axis B0325B, reflecting the added Y-axis mechanism, FANUC 32i-B control (vs. 0i-TF Plus), and additional live tooling capacity. Whether it's worth the premium depends on whether your parts need off-center features.
05
Yes. The 3.7/5.5 kW spindle motor provides adequate power for Inconel, Hastelloy, and similar alloys at the reduced speeds and feeds these materials require. The machine's rigidity handles the high cutting forces. Use appropriate carbide or ceramic tooling, high-pressure coolant, and conservative cutting parameters for best results.
