Overview
The Tsugami S205-II is a 5-axis opposed gang tool Swiss-type CNC lathe with 20 mm (0.8 in) bar capacity, representing Tsugami's modular tool zone approach to high-volume precision production. This is a serious production machine built around the concept of cartridge-type live tooling that can be swapped quickly without re-qualifying the entire setup.
The numbers tell the story: 200-10,000 RPM on both the main and sub-spindle, 2.2/3.7 kW (2.9/5 hp) spindle motor, and live tooling running at 10,000 RPM across up to 16 live tool positions. Standard configuration starts with 25 tool stations and maxes out at 39, giving you the flexibility to keep backup tools loaded for extended unattended runs. The FANUC 32i-B control manages the 5-axis coordination, and rapid traverse clocks in at 35 m/min to keep cycle times tight.
The convertible guide bushing system is a standout feature. With the guide bushing installed, you get up to 210 mm (9.84 in) of machining length for long, slender parts. Remove it and run in chucker mode with 45 mm (1.77 in) of stroke for shorter parts where you don't want the material waste associated with guide bushing remnants. This flexibility means one machine can cover a wider range of part geometries.
At 3,750 kg (8,267 lbs) with dimensions of 2,325 x 1,270 x 1,970 mm (91 x 50 x 77.5 in), the S205-II is a mid-weight Swiss machine. It competes directly with the Citizen L20 and Star SR-20 series in the 20mm class, and its modular tool zone design is Tsugami's answer to the quick-change tooling systems those competitors offer. For shops running mixed-part production with frequent changeovers, the cartridge tooling system can meaningfully reduce downtime between jobs.

Strengths & Limitations
Strengths
- 10,000 RPM live tooling speed is best-in-class for 20mm Swiss machines, enabling productive milling and cross-drilling operations
- Convertible guide bushing/chucker system covers both long slender parts (210mm) and short parts (45mm) on one machine
- Up to 39 tool positions with 16 live stations handles complex parts and keeps backup tools loaded for unattended runs
- Cartridge-type modular tool zone enables fast changeovers by swapping pre-set tooling cassettes
- 35 m/min rapid traverse rate minimizes non-cutting time between tool changes and positioning moves
- FANUC 32i-B control is a proven platform with extensive support network and third-party software compatibility
Limitations
- 5-axis configuration lacks the Y2-axis of the S206-II, limiting back-side milling to on-center operations
- 3,750 kg machine weight requires adequate floor loading capacity and makes relocation more involved
- Modular tool zone cartridges are proprietary to Tsugami, limiting third-party tooling options for some configurations
- 20mm bar capacity may be insufficient for shops occasionally running larger diameter work

Frequently Asked Questions
01
The S206-II adds a Y-axis (6th axis) that enables off-center milling, drilling, and contouring on the back side of the part via the sub-spindle. The S205-II is limited to on-center back-working. The S206-II also offers more total tool positions (31/45 vs. 25/39). Choose the S206-II if your parts require complex back-end features; the S205-II is sufficient and less expensive for simpler back-side operations.
02
The S205-II can be configured with a guide bushing for long, slender parts (up to 210mm machining length) or without it in chucker mode for shorter parts (45mm stroke). Switching between modes requires some mechanical adjustment but doesn't require specialized equipment. This flexibility lets one machine handle a wider range of part geometries and eliminates guide bushing remnant waste on short parts.
03
The tool zone uses pre-settable cartridges that slide into standardized stations. You can set up tooling for the next job offline while the current job is still running, then swap the cartridges during changeover. This can cut changeover time by 30-50% compared to individually replacing and touching off each tool. It's especially valuable for shops running multiple part numbers across shifts.
04
Both are excellent 20mm Swiss machines. The Citizen L20 offers LFV chip-breaking technology as an option, which is a significant advantage for stringy materials. The Tsugami S205-II counters with its modular cartridge tool zone for faster changeovers and 10,000 RPM live tooling (vs. typically 6,000-8,000 RPM on the L20). Service and support availability may vary by region.
05
New S205-II machines typically price between $250,000 and $380,000 depending on tooling configuration, options, and bar feeder. The base configuration with standard tooling is at the lower end; fully loaded with maximum live tools, high-pressure coolant, and a bar feeder pushes toward the upper range. Used units from the S205 generation (pre-II) may be available in the $120,000-$200,000 range.
