Overview

The Tsugami B0266 is a 26 mm Swiss-type automatic lathe built around a 6-linear-axis architecture that delivers exceptional versatility for complex small-part production. Positioned within Tsugami's B-series lineup, the B0266 extends the proven B026x platform with a streamlined six-axis configuration that balances capability and setup simplicity — making it an attractive choice for shops that need Swiss-type precision without the overhead of a full B-axis or Y-axis mill configuration.

With a 26 mm bar capacity and 10,000 RPM main spindle, the B0266 targets the same medical, aerospace, and electronics markets as Tsugami's other 26 mm machines, but its 6-axis layout — typically comprising X1, Z1, X2, Z2, and two additional linear axes for gang tooling or back-working — enables a wide range of front-work and back-work operations in a single setup. Tool capacity reaches 20 to 24 stations depending on configuration, covering OD turning, boring, drilling, threading, and transverse milling.

The guide bushing system ensures the bar stock is supported close to the cutting zone, keeping deflection minimal for long slender parts where taper and straightness are critical. Like other Tsugami B-series machines, the B0266 accepts the optional guide bushing removal kit for conversion to fixed-headstock mode, which reduces material remnants when running shorter part programs.

The Fanuc 32i-B control provides the programming environment, offering macro capability, high-speed look-ahead, and Ethernet connectivity for DNC integration. Tsugami's North American distribution through REM Sales supports the B0266 with applications engineering, spare parts, and field service across the US and Canada. List pricing typically falls in the $165,000 to $220,000 range depending on tooling configuration and options. Comparable machines include the Citizen L20, Star SR-20J, and Tornos GT 26.

Strengths & Limitations

Strengths

6-axis linear configuration covers the majority of complex Swiss-type part geometries without the programming complexity of a full B-axis machine
26 mm bar capacity and 10,000 RPM spindle handle the full range of medical, aerospace, and electronics small-part production
Guide bushing system maintains close bar support for long slender parts, holding ±0.005 mm tolerances on shafts and screws
Removable guide bushing option reduces material waste for shorter parts, cutting remnant loss in expensive alloys like titanium
Fanuc 32i-B control provides reliable operation, macro programming, and straightforward DNC networking for lights-out production
REM Sales North American support network provides competitive parts and service response against Citizen and Star dealers

Limitations

6-axis configuration without a B-axis limits angular drilling capability; shops needing off-angle holes require a more advanced model like the B0326
Sub-spindle at 8,000 RPM is lower than the main spindle, which can be a constraint for demanding back-work operations
$165K entry price requires solid production volume commitment to justify return on investment for smaller shops
24-tool capacity may limit flexibility for highly complex parts requiring more than two tooling changeovers per cycle

Best For

Medical device shops producing bone screws, pins, and small-diameter shafts requiring Swiss-type accuracy without B-axis complexity Automotive and electronics manufacturers running high-volume 26 mm and under parts where 6-axis capability is sufficient for the part mix Contract shops looking for a cost-effective entry into 26 mm Swiss-type production with Tsugami brand reliability and REM Sales support Shops transitioning from fixed-headstock CNC lathes who want Swiss-type precision in a configuration that minimizes operator retraining

Frequently Asked Questions

01 How does the B0266 differ from the B0326?

The primary difference is axis count and tooling density. The B0326 offers up to 7 axes including B-axis capability and up to 27 tool stations, while the B0266 provides 6 linear axes and up to 24 tools. The B0266 is better suited for parts that require front and back turning plus basic milling, while the B0326 handles angular drilling, thread whirling, and more complex multi-feature geometries. Both share the same 26 mm bar capacity and 10,000 RPM main spindle.

02 Can the B0266 perform cross-drilling and milling?

Yes. The B0266 supports live tooling for cross-drilling and transverse milling operations through its gang-mounted driven tool positions. The 6-axis configuration handles hex drives, cross-holes, slots, and flat features that are common in medical and automotive parts. For off-angle features requiring B-axis rotation, the B0326 or B0386 would be more appropriate.

03 What is the maximum part length the B0266 can produce?

The B0266 can produce parts up to approximately 200 mm (7.87 in) in length in guide bushing mode, determined by the Z1 axis travel. For longer parts, the sub-spindle pick-off extends the effective machined length by allowing the part to be transferred and back-worked. Non-guide bushing mode is generally limited to parts shorter than about 3x bar diameter to avoid deflection issues.

04 Is the B0266 suitable for titanium machining?

Yes, with proper tooling and coolant setup. Titanium Ti-6Al-4V is a common material in medical Swiss-type work and the B0266 handles it well with carbide tooling, high-pressure coolant (50-70 bar recommended), and conservative cutting parameters. The guide bushing support is essential for titanium to minimize vibration and maintain surface finish on long slender parts.

05 What bar feeder is compatible with the B0266?

The B0266 is compatible with standard hydrodynamic and magazine bar feeders designed for Swiss-type lathes. LNS and IEMCA units for 26 mm stock are common pairings. A 12-foot LNS Alpha or IEMCA Boss 332 adds approximately $20,000-$28,000 to the total investment. Tsugami and REM Sales can specify compatible feeders for the installation.
