Overview
The Tsugami S206-II is a 6-axis opposed gang tool Swiss-type CNC lathe with 20 mm (0.8 in) bar capacity and Y-axis capability on the tool post. It's the fully-featured version of the S205-II, adding the critical Y-axis that opens up off-center milling, drilling, and contouring operations that the 5-axis model can't touch.
The spec sheet is impressive for a 20mm-class machine. Main and sub-spindles both run at 200-10,000 RPM with 2.2/3.7 kW (2.9/5 hp) of power. Live tooling hits 10,000 RPM, and you get up to 45 tool positions in the maximum configuration with the standard starting at 31. The modular tool zone uses Tsugami's cartridge-type live tools that can be pre-set offline and swapped during changeovers, which is a real productivity advantage for shops running multiple part numbers.
The convertible guide bushing system gives you four distinct operating modes: stationary guide bushing with 250 mm (9.8 in) machining length, direct-drive rotary guide bushing with 210 mm (8.3 in), guide-bushless chucker mode with 45 mm (1.8 in), and carrier rotary mode with 80 mm (3.1 in). That's more flexibility than most competitors offer, and it means one machine can genuinely cover a broad range of part geometries without compromise.
The FANUC 32i-B control handles the 6-axis interpolation, and rapid traverse at 35 m/min keeps positioning moves quick. At 3,750 kg (8,267 lbs) and 2,325 x 1,270 x 1,970 mm (91.5 x 50 x 77.5 in), it's the same physical size as the S205-II. The S206-II is Tsugami's answer for shops that need maximum flexibility and capability in the 20mm Swiss class.

Strengths & Limitations
Strengths
- 6-axis with Y-axis enables off-center milling, hex profiling, and complex contouring that 5-axis machines can't produce
- Four convertible guide bushing modes (stationary, rotary, bushless, carrier) provide unmatched flexibility for diverse part geometries
- Up to 45 tool positions with 10,000 RPM live tooling handles even the most complex multi-feature parts in a single setup
- 250 mm machining length in stationary guide mode is generous for the 20mm bar class
- Cartridge-type modular tool zone cuts changeover time with pre-settable tooling cassettes
- 35 m/min rapid traverse rate minimizes non-cutting time for shorter cycle times
Limitations
- Premium pricing over the S205-II for the added Y-axis and tooling capacity may not be justified for simpler parts
- Complexity of 4 guide bushing modes adds setup considerations and training requirements for operators
- 3,750 kg weight requires solid floor loading and makes the machine difficult to relocate
- Proprietary cartridge tooling system limits some third-party tooling options

Frequently Asked Questions
01
The S206-II can run in four configurations: (1) stationary guide bushing for maximum machining length at 250mm, (2) direct-drive rotary guide bushing at 210mm for improved surface finish on some materials, (3) guide-bushless chucker mode at 45mm stroke for short parts without guide bushing waste, and (4) carrier rotary mode at 80mm for specific applications. Each mode has trade-offs in terms of part length capability, surface finish, and material usage.
02
Both are top-tier 20mm Swiss machines. The Citizen L20 offers LFV chip-breaking technology and a well-proven turret-style tool zone. The Tsugami S206-II counters with its four-mode guide bushing flexibility, 10,000 RPM live tooling, and modular cartridge tool system. The S206-II also offers more total tool positions (45 max vs. typically 36-40 on the L20). Choice often comes down to dealer support in your region and existing fleet standardization.
03
It depends entirely on your parts. If you're machining features that require off-center work -- hex profiles, flats, eccentric holes, keyways -- the Y-axis is essential and the premium pays for itself by eliminating secondary operations. If your parts only need on-center turning, drilling, and threading, save the money and go with the S205-II.
04
In stationary guide bushing mode, you get 250mm (9.8 in) of machining length, which is the maximum. Direct-drive rotary mode gives you 210mm (8.3 in). In guide-bushless chucker mode, the stroke is limited to 45mm (1.8 in). The mode you select depends on the part's requirements for length, surface finish, and material economy.
05
The S206-II runs on the FANUC 32i-B control, which is a premium CNC platform capable of smooth 6-axis interpolation. It supports macro programming, high-speed execution, and is compatible with most third-party CAM software for Swiss-type programming. Tsugami's automatic programming overlay is also available to simplify common operations.
