How much does the Tsugami S205A-II cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Tsugami. Configuration moves it a long way.
Overview
The Tsugami S205A-II is a 20 mm (0.79 in) Swiss-type lathe from Tsugami's S20x line, listed with 27 tools as standard. On paper its two spindles are identical: 10,000 rpm maximum (rated 8,000 rpm) and 2.2/3.7 kW each, so the sub spindle is a full partner for back-end work rather than a light pickup.
Tsugami's table splits rapid traverse by axis. Z1, X2 and Z2 move at 35 m/min, while X1, Y1 and Y2 move at 24 m/min. The faster group covers the headstock's Z stroke and the back side, where most of the non-cutting distance is travelled. The Y1 and Y2 entries show a Y axis on both the front and the back, which is what off-centre drilling and milling on either end of a part needs.
Within the family, the S206A-II shares this spindle data, the rapids and the 3,750 kg (8,267 lb) weight, but carries 31 tools as standard against 27. The B0125C, at 1,800 kg (3,968 lb), has 21 tools and runs its spindle to 12,000 rpm (rated 10,000 rpm). The S205A-II sits between them: more tools and mass than the B0125C, four fewer tools than the S206A-II.
Floor space is 2,325 × 1,270 × 1,970 mm (91.5 × 50.0 × 77.6 in). The table gives no machining length per chucking, guide-bushing details, live-tool speed or control, so get those from Tsugami before quoting a part.

Strengths & Limitations
Strengths
- 27 tools as standard on a 20 mm (0.79 in) machine
- Main and sub spindles matched at 10,000 rpm (rated 8,000 rpm) and 2.2/3.7 kW
- Rapid traverse of 35 m/min on Z1, X2 and Z2
- Y1 and Y2 axes in the rapid row, so off-centre features can be cut from either side
Limitations
- X1, Y1 and Y2 rapid at 24 m/min, well below the 35 m/min of the Z axes
- Four fewer tools than the 31 standard on the S206A-II
- No machining length, live-tool speed or control in Tsugami's table
- Weighs 3,750 kg (8,267 lb) against 1,800 kg (3,968 lb) for the B0125C, so check floor loading and rigging

Frequently Asked Questions
01
Tsugami's table separates them by one row: the S205A-II carries 27 tools as standard and the S206A-II 31. Machining diameter of 20 mm (0.79 in), 10,000 rpm (rated 8,000 rpm) on both spindles, 2.2/3.7 kW, the rapids and the 3,750 kg (8,267 lb) weight are listed the same.
02
On paper, yes. Tsugami lists the sub spindle at 10,000 rpm (rated 8,000 rpm) and 2.2/3.7 kW, the same as the main spindle. Drilled ends, threads and chamfers on the back of a part can therefore be cut at the same speeds and power as front-end work.
03
35 m/min on Z1, X2 and Z2, and 24 m/min on X1, Y1 and Y2. The long Z moves are the fast ones, which is where a Swiss-type spends most of its positioning time.
