How much does the Tsugami SS20 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 SS20 is the 20 mm (0.79 in) model of Tsugami's SS Swiss-type line: six axes, a guide bushing that can be removed for chucker mode, a FANUC 32i-B control and 24/40 tool stations, 10/13 of them for live tools. Main and sub spindles both run 200 - 10,000 rpm and the main spindle is rated 2.2 / 3.7 kW (3 / 5 hp).
Machining length per chucking is 220 mm (8.66 in) with the guide bushing and 45 mm (1.77 in) without it. The long figure covers slender shafts and pins; chucker mode is for short, stocky parts where losing the remnant behind a guide bushing would waste costly bar.
The SS20 shares its frame figures with the larger SS26 and SS32: all three are listed at 3,400 kg (7,495 lb), 2,020 × 1,675 × 2,020 mm (79.5 × 65.9 × 79.5 in), 24/40 tool stations and 5,000 rpm live tools. What sets the SS20 apart is the smaller bar and the 2.2 / 3.7 kW (3 / 5 hp) spindle, against 3.7 / 5.5 kW (5 / 7.4 hp) on the SS26. A shop running all three sizes can use the same cell layout and tooling approach across them.
The live-tool speed is the figure to weigh. At 5,000 rpm, small drills and end mills run well below their ideal speed, so parts with fine cross holes or small milled features will cycle slower than on a machine with faster driven tools. The SS20MH-III-5AX, for comparison, lists 10,000 rpm on backworking and 25,000 rpm on its tool spindle, on a 5,300 kg (11,660 lb) machine.

Strengths & Limitations
Strengths
- Six axes with 24/40 tool stations and 10/13 live positions
- 220 mm (8.66 in) per chucking with the guide bushing, 45 mm (1.77 in) in chucker mode
- Main and sub spindles both run 200 - 10,000 rpm
- Same 2,020 × 1,675 × 2,020 mm (79.5 × 65.9 × 79.5 in) footprint as the SS26 and SS32
- FANUC 32i-B control, shared with the SS26 and SS32
Limitations
- Live tools run only to 5,000 rpm, slow for small drills and end mills
- Main spindle rated 2.2 / 3.7 kW (3 / 5 hp), less than the 3.7 / 5.5 kW (5 / 7.4 hp) of the SS26
- Chucker mode limits machining length per chucking to 45 mm (1.77 in)
- Tsugami America's table gives no rapid traverse or axis strokes

Frequently Asked Questions
01
Bar size, machining length and spindle power. The SS20 takes 20 mm (0.79 in) bar, machines 220 mm (8.66 in) per chucking and has a 2.2 / 3.7 kW (3 / 5 hp) main spindle. The SS26 takes 26 mm (1.02 in), machines 270 mm (10.62 in) and has 3.7 / 5.5 kW (5 / 7.4 hp). Tool stations, live-tool speed, weight and footprint are listed the same.
02
220 mm (8.66 in) per chucking with the guide bushing. In chucker mode, with the bushing removed, it is 45 mm (1.77 in). Parts longer than the per-chucking figure are machined in several chuckings, which adds cycle time and needs care over concentricity.
03
Up to 5,000 rpm, on 10/13 live positions. That is enough for drilling and milling at moderate sizes, but small tools will run below their best cutting speed. If fine milled or drilled features dominate the work, compare with the SS20MH-III-5AX, whose tool spindle is listed at 25,000 rpm.
04
Tsugami America lists 2,020 × 1,675 × 2,020 mm (79.5 × 65.9 × 79.5 in) and 3,400 kg (7,495 lb). That footprint is deeper and shorter than the 2,325 × 1,270 mm of the S205-II, which can matter when fitting a machine into an existing row.
