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 B0266 is a 6-axis Swiss-type lathe for bar from 8 to 26 mm (0.31 to 1.02 in), listed in Tsugami's B0 Series catalogue as the B0266-II. Its main feature is a direct-drive rotary guide bushing, rated 200 to 10,000 min-1, which gives up to 320 mm (12.6 in) of machining per chucking. Run guide-bush-less, the stroke is 50 mm (1.97 in).
The main spindle covers 200 to 10,000 min-1 on a 3.7 / 5.5 kW (5.0 / 7.4 hp) motor and drills to 12 mm and taps to M10. The back spindle chucks the full 26 mm (1.02 in), runs over the same speed range on a 2.2 / 3.7 kW (3.0 / 5.0 hp) motor, and drills to 10 mm and taps to M10. One catch: with the rotary tool beside the back spindle mounted, back-spindle speed is limited to 8,000 min-1.
Tooling is 31 positions as standard and 43 with the option, with turning tools of 16 x 16 x 100 mm. Driven tools run from 200 to 6,000 min-1 on a 1.0 kW cross-drill motor, rated for 8 mm cross drilling, M6 cross tapping and slotting cutters up to 45 mm in diameter. That speed ceiling is the main limit for small end mills and drills. The six linear axes are X1, Z1, Y1, X2, Z2 and Y2, plus C1 and C2 on the spindles. Rapid traverse is 32 m/min, with X1, Y1 and Y2 at 24 m/min.
The control is a FANUC 32i-B with 99 tool offset pairs and a 10.4-inch colour LCD. Before delivery, plan for a 21.4 kVA supply, compressed air at 0.4 MPa or above and 40 NL/min, a 180 L coolant tank, and a machine of 3,500 kg (7,716 lb) measuring 2,150 x 1,280 x 1,930 mm (84.6 x 50.4 x 76.0 in).

Frequently Asked Questions
01
The working bar diameter is 8 to 26 mm (0.31 to 1.02 in), and the back spindle chucks up to 26 mm (1.02 in), so a part can be transferred at full bar diameter. Turning tools are 16 x 16 x 100 mm.
02
It is driven directly and turns at 200 to 10,000 min-1, the same range as the main spindle, so the bar rotates with the bushing instead of spinning inside a fixed one. That is what allows 320 mm (12.6 in) of machining per chucking. Without the bushing the machine works guide-bush-less with 50 mm (1.97 in) of stroke.
03
They run from 200 to 6,000 min-1 on a 1.0 kW motor. The catalogue rates them for 8 mm cross drilling, M6 cross tapping and slotting cutters up to 45 mm in diameter; back drilling is rated to 8 mm and back tapping to M6. Larger features belong on the main or back spindle, which drill to 12 mm and 10 mm.
04
A 21.4 kVA power supply and compressed air at 0.4 MPa or above with 40 NL/min. The coolant tank holds 180 L and the pump is rated 0.4 kW. The machine measures 2,150 x 1,280 x 1,930 mm (84.6 x 50.4 x 76.0 in) and weighs 3,500 kg (7,716 lb), before any bar feeder.
05
A FANUC 32i-B with a 10.4-inch colour LCD in Japanese or English, 99 tool offset pairs and a least input increment of 0.001 mm. Program storage is 64 kbyte, with 63 registerable programs shared between the main and back spindle paths.
