Overview
The Tsugami B0326 is a 26 mm capacity Swiss-type automatic lathe built for high-precision, high-volume production of complex small parts. Tsugami is one of the leading Swiss-type lathe manufacturers globally, and the B0326 sits in their core production lineup targeting medical device, electronics, automotive, and watchmaking industries where tight tolerances and fine surface finishes are non-negotiable.
The B0326 handles bar stock up to 26 mm (1.024 in) diameter with a main spindle speed of 10,000 RPM and a sub-spindle rated at 10,000 RPM as well. The main spindle delivers 3.7 kW (5 hp) of continuous power, which is well-suited for the small-diameter precision work this machine targets. With up to 7 axes including B-axis capability for angular drilling and milling, the B0326 can produce complete parts in a single setup, eliminating secondary operations that add cost and reduce accuracy.
The machine features up to 27 tools across front, back, and gang-mounted positions, giving it exceptional tool density for complex part geometries. Cross-drilling, thread whirling, polygon turning, and off-center milling are all possible with the available tooling configurations. The guide bushing system ensures minimal deflection during cutting, which is critical for achieving the ±0.005 mm tolerances common in medical bone screws and dental implant components.
The B0326 runs on the Fanuc 32i-B control, providing reliable CNC operation with macro programming capability and network connectivity. Tsugami's TS series software overlay simplifies setup for operators transitioning from simpler turning centers. Pricing for the B0326 typically runs $180,000 to $250,000 depending on axis configuration, tooling packages, and options like high-pressure coolant and oil mist systems. Direct competitors include the Citizen L20, Star SR-20J, and Tornos GT 26. Tsugami has a strong North American presence through their partnership with REM Sales, ensuring reasonable parts and service availability across the US.

Strengths & Limitations
Strengths
- 26 mm bar capacity with up to 7 axes and 27 tools enables complete part production in a single setup, eliminating costly secondary operations
- 10,000 RPM main and sub spindles provide excellent surface speed for both ferrous and non-ferrous materials at small diameters
- Guide bushing system minimizes bar deflection for ±0.005 mm tolerances on long slender parts like medical bone screws and dental implants
- B-axis capability allows angular drilling and milling operations that would otherwise require separate fixturing and machine time
- Strong North American support through REM Sales ensures parts availability and service response competitive with Citizen and Star
- Removable guide bushing allows conversion to non-guide bushing mode for shorter parts, reducing material waste from remnant bar stock
Limitations
- Swiss-type setup complexity requires experienced operators; shops transitioning from conventional CNC lathes should budget 3-6 months for training
- $180K+ entry price is a significant investment for shops without guaranteed production volume to keep the machine running
- 3.7 kW main spindle limits heavy material removal; this is a precision finishing machine, not a roughing platform
- 27-tool capacity requires careful planning for tool interference and clearance in the tight Swiss-type work zone

Frequently Asked Questions
01
Both are 20-26 mm Swiss-type lathes targeting similar applications. The B0326 offers slightly higher tool density with up to 27 tools vs the Citizen's typical 20-24 tool configuration. The Citizen L20 counters with Citizen's LFV (Low Frequency Vibration) chip breaking technology, which is a significant advantage for stringy materials like stainless steel and titanium. Both machines hold similar tolerances and pricing. The choice often comes down to dealer relationship and existing shop experience with the respective control interfaces.
02
Yes. The B0326 features a removable guide bushing that allows conversion to non-guide bushing (fixed headstock) mode. This is advantageous for shorter parts where the guide bushing would waste material in the remnant bar. Non-guide bushing mode reduces material waste by approximately 200-300 mm per bar, which adds up significantly in expensive materials like titanium or Inconel.
03
The B0326 handles a full range of bar stock materials including free-machining steels, stainless steels (303, 304, 316), titanium alloys (Ti-6Al-4V), brass, aluminum, and engineering plastics like PEEK and Delrin. For difficult materials like titanium and Inconel, high-pressure coolant (up to 70 bar) is recommended. The 10,000 RPM spindle speed provides adequate surface speed for most materials at the small diameters this machine targets.
04
Cycle times vary with part complexity, but a typical medical bone screw (8-15 mm diameter, 25-40 mm length) with thread whirling, cross-holes, and hex drive runs in 30-60 seconds on the B0326. High-volume shops producing simpler turned parts like dowel pins or connector contacts can achieve cycle times under 15 seconds. The dual-spindle configuration overlaps main and sub-spindle operations to minimize total cycle time.
05
Tsugami typically pairs the B0326 with LNS or IEMCA hydrodynamic bar feeders designed for Swiss-type applications. A 12-foot magazine bar feeder for 26 mm stock adds approximately $20,000-$30,000. For maximum unattended runtime, LNS Alpha SL65 or IEMCA Boss 332 are popular choices among B0326 users. The bar feeder interface is standardized, so most major bar feeder brands are compatible.
06
The B0326 has a relatively compact footprint of approximately 2,500 x 1,200 mm (98 x 47 in) plus bar feeder length. With a standard 12-foot bar feeder, total length extends to about 6,000 mm (236 in). The machine weighs 2,700 kg and does not require special foundation work beyond a level concrete floor. Multiple B0326 machines can be arranged in tight cell configurations for high-volume production.
