Overview
The Tsugami S206A-II is an enhanced 6-axis opposed gang tool Swiss-type CNC lathe with 20 mm (0.8 in) bar capacity and Y-axis capability. It's the top-spec machine in the S-series 5/6-axis lineup, combining the Y-axis milling capability of the S206-II with the automation enhancements carried by the 'A' designation.
The core platform delivers 200-10,000 RPM on both main and sub-spindles with a 2.2/3.7 kW motor. Live tooling runs at 10,000 RPM across up to 24 live tool positions in the maximum configuration, with estimated total tool capacity of 31/45 positions. The 6-axis configuration with Y-axis enables off-center drilling, milling, hex profiling, and contouring that the 5-axis S205A-II can't match. This is the machine you want when your parts have complex features on both the front and back sides.
The convertible guide bushing system supports both Swiss operation and guide-bushless chucker mode, and the modular tool zone with cartridge-type tooling keeps changeovers efficient. Rapid traverse at 35 m/min ensures positioning moves don't drag down cycle times. The estimated weight of 3,750 kg (8,267 lbs) and footprint are consistent with the S206-II platform.
Note that specific 'A' variant enhancements aren't fully documented in public specifications, and some specs are estimated from the base S206-II model. In Tsugami's convention, the A designation typically points to improved automation integration, enhanced production software, or additional features that support higher-volume and lights-out manufacturing. For shops that need both Y-axis capability and enhanced automation on a 20mm Swiss platform, the S206A-II is the most capable option in the S-series lineup.

Strengths & Limitations
Strengths
- 6-axis with Y-axis enables off-center milling, hex profiling, and complex contouring on both sides of the part
- Up to 24 live tool positions at 10,000 RPM is one of the highest live tooling counts in the 20mm Swiss class
- Enhanced 'A' variant adds automation features oriented toward higher-volume and lights-out production
- Convertible guide bushing system handles both long Swiss parts and short chucker parts on one machine
- Cartridge-type modular tool zone enables fast offline pre-setting and quick changeovers
- Estimated 31/45 total tool positions keep backup tools loaded for extended unattended runs
Limitations
- Highest-priced option in the S-series 20mm lineup -- the premium only pays off if you need both Y-axis and automation features
- Some specifications are estimated from the base S206-II since A-variant details aren't independently published
- Complexity of 6-axis programming requires experienced operators or quality CAM software
- Proprietary cartridge tooling system may limit some third-party tooling options

Frequently Asked Questions
01
Choose the S206A-II when your parts require off-center features -- hex profiles, flats, eccentric holes, keyways, or contoured surfaces that need Y-axis movement. If all your features are on-center, the S205A-II handles them at a lower cost. The S206A-II also offers more total tool positions (estimated 31/45 vs. 25/39), which matters for complex parts or backup tooling for unattended runs.
02
The 'A' designation in Tsugami's naming convention typically denotes enhanced automation or production features. Exact differences aren't fully detailed in public specs, but the A variant is oriented toward higher-volume production with improved bar loading integration, production software, or additional automation support. Contact your Tsugami dealer for current A-variant specifications.
03
The S206A-II supports up to 24 live tool positions running at 10,000 RPM. That's a lot of live tooling capacity -- enough for complex parts requiring multiple cross-drills, milling operations, and threading from different angles. Standard configuration starts lower and can be expanded based on your tooling needs.
04
Yes. The 2.2/3.7 kW spindle motor and 200-10,000 RPM speed range are well-suited for titanium grades commonly used in medical and aerospace applications (Ti-6Al-4V, CP Grade 2). You'll run at lower speeds (typically 500-2,000 RPM for turning) with appropriate carbide or PCD tooling. The machine's rigidity handles the cutting forces involved.
05
Most major Swiss-type CAM packages support the S206-series platform: PartMaker (now part of Autodesk), ESPRIT, GibbsCAM, and PrimeTurning from Sandvik. The FANUC 32i-B control is a standard platform, so post-processor availability is good. Tsugami also provides automatic programming software that handles common operations without external CAM.
