How much does the Tsugami SS327-III-5AX 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 SS327-III-5AX is the B-axis version of the SS327-III: a seven-axis Swiss-type lathe for bar up to 32 mm (1.25 in), with 36 tool stations and a FANUC 31i-B5 control. Tsugami America lists the live-tool positions as 18/20 and gives the B-axis tools a top speed of 7,000 rpm, against 6,000 rpm for the other driven tools.
The machine runs either with a guide bushing or in chucker mode, and the choice changes the part it can make. With the bushing, one chucking covers up to 330 mm (12.99 in) of length, enough for long shafts and pins. Without it the limit is 70 mm (2.74 in), which suits short, stubby parts where running without the bushing usually means a shorter bar remnant and less need for tightly toleranced bar stock.
Main and sub spindles share a 200 to 8,000 rpm range, and the main spindle is rated 3.7 / 5.5 kW (5 / 7.4 hp). The table does not give a separate sub-spindle power figure or any rapid traverse rates, so ask for both if back-end cycle time matters on the job.
Among Tsugami's B-axis Swiss machines, the SS207-II-5AX runs the same 31i-B5 control at 3,745 kg (8,267 lb). The SS20MH-III-5AX is the choice when small cutters need speed: its tool spindle reaches 25,000 rpm and its backworking tools 10,000 rpm, on a 5,300 kg (11,660 lb) frame with the 31i-B5 Plus control.
This machine weighs 4,000 kg (8,800 lb) and its footprint is 2,150 × 1,280 × 2,010 mm (84.6 × 50.3 × 79.1 in).

Strengths & Limitations
Strengths
- B-axis live tools run to 7,000 rpm, so angled holes and faces are machined in the same cycle
- Up to 330 mm (12.99 in) of machining length per chucking with the guide bushing
- Chucker mode is available for short parts, with 70 mm (2.74 in) of machining length
- 36 tool stations, with live tooling listed as 18/20 positions
- Main and sub spindles both cover 200 to 8,000 rpm
- Seven controlled axes on a FANUC 31i-B5 control
Limitations
- Live tools top out at 7,000 rpm; the SS20MH-III-5AX runs its tool spindle to 25,000 rpm for small cutters
- Without the guide bushing, machining length per chucking falls to 70 mm (2.74 in)
- Only main spindle power is listed, 3.7 / 5.5 kW (5 / 7.4 hp); there is no sub-spindle power or rapid traverse figure
- Driven tools other than the B-axis tools are limited to 6,000 rpm

Frequently Asked Questions
01
A B axis for angled live tooling, with B-axis tools running to 7,000 rpm and the other driven tools to 6,000 rpm, and a FANUC 31i-B5 control. The SS327-III's table lists 38 tools as standard and an 8,000 rpm main spindle rated 6,000 rpm at 3.7/5.5 kW. Both machines weigh 4,000 kg.
02
Up to 330 mm (12.99 in) with the guide bushing in place. In chucker mode, without the bushing, the limit is 70 mm (2.74 in). Longer parts need re-chucking, which on a Swiss-type machine means the headstock regripping the bar during the cycle.
03
Yes. Tsugami America lists chucker mode for this machine. It is meant for short parts up to 70 mm (2.74 in) of machining length, where the support of the bushing is not needed and dropping it can save bar.
04
7,000 rpm for the B-axis tools and 6,000 rpm for the other driven positions. That covers drilling, tapping and milling with mid-size cutters on 32 mm (1.25 in) work. For very small end mills, the SS20MH-III-5AX offers 25,000 rpm on its tool spindle.
05
4,000 kg (8,800 lb), with a footprint of 2,150 × 1,280 × 2,010 mm (84.6 × 50.3 × 79.1 in). Confirm whether a bar feeder is included in that length when planning the floor layout.
