How much does the Tsugami BW127-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 BW127-II is the plainest machine in the 12 mm BW group: a Swiss-type automatic lathe for bar up to 12 mm (0.47 in) in diameter, with 24 tools as standard and a main spindle that runs to 12,000 rpm (rated 10,000 rpm). Its rapid traverse row names seven axes, X1, Y1, Z1, X2, Z2, X3 and Y3. That list is what separates it from the rest of the family, because it has neither the Y2 axis nor the Z3 axis that the other variants add.
Both spindles are the same size here. Main and back spindle are each rated 1.5/2.2 kW, and the back spindle reaches 12,000 rpm (rated 8,000 rpm), so the cut-off end of a small part can be finished at speeds close to those used on the front.
Z1, X2 and Z2 traverse at 32 m/min, Y1 and Y3 at 24 m/min, and X1 and X3 at 12 m/min. The machine stands 2,010 × 1,505 × 1,750 mm (79.1 × 59.3 × 68.9 in) and weighs 2,850 kg (6,283 lb).
Choosing it over the BW128-II means doing without a Y2 axis, which that model moves at 15 m/min, and accepting 24 tool positions against 28. The BW128Z-I keeps the 24-tool count but adds a Z3 axis with 60 mm (2.36 in) of stroke. If the parts in view need neither, the BW127-II is the simpler machine to start from.

Strengths & Limitations
Strengths
- Takes bar up to 12 mm (0.47 in) with a main spindle that runs to 12,000 rpm (rated 10,000 rpm)
- Back spindle matches the main spindle at 1.5/2.2 kW and reaches 12,000 rpm (rated 8,000 rpm)
- Seven axes and 24 tools as standard, with 32 m/min rapids on Z1, X2 and Z2
- The lightest of the 12 mm BW machines at 2,850 kg (6,283 lb), shared with the BW128Z-I
Limitations
- No Y2 axis: the BW128-II adds one at 15 m/min and carries 28 tools against 24
- No Z3 axis, so the third tool group has no axial stroke of its own, unlike the BW128Z-I with 60 mm (2.36 in)
- X1 and X3 move at 12 m/min, well below the 32 m/min of the Z axes

Frequently Asked Questions
01
The BW128-II adds a Y2 axis, which it moves at 15 m/min, and carries 28 tools as standard against 24 on the BW127-II. It weighs 2,900 kg (6,393 lb) against 2,850 kg (6,283 lb). Bar capacity, spindle speeds and spindle power are the same on both.
02
The maximum machining diameter is 12 mm (0.47 in). For bigger stock the 20 mm machines of the same layout apply, such as the BW207-II, which takes 20 mm (0.79 in) with a 2.2/3.7 kW main spindle.
03
The main spindle runs to 12,000 rpm with a rated speed of 10,000 rpm. The back spindle also reaches 12,000 rpm, rated 8,000 rpm. Both are rated 1.5/2.2 kW.
