Overview
The Tsugami B0128W is a 9-axis Swiss-type CNC automatic lathe with a 12 mm (0.5 in) bar capacity that combines independent opposed tool posts with a back tool post Y-axis for diverse simultaneous processing. The W suffix in Tsugami's naming convention indicates the independent opposed tool post design, setting it apart from the standard B012x gang tool post models.
With 9 axes, the B0128W runs 3-path simultaneous control — front tool post, rear tool post, and back tool post operations can all run concurrently. The main spindle reaches 200-12,000 RPM and the sub spindle matches at 200-12,000 RPM, powered by a 1.5/2.2 kW motor. Live tooling runs at 8,000 RPM for cross-drilling and milling operations. The combination of independent opposed posts and the back tool post Y-axis enables a particularly flexible tool layout.
Modular tooling is a key feature — it enables optimal tool allocation for different part geometries without changing the entire tool post configuration. Automatic programming software comes standard, reducing the barrier to entry for shops that aren't deeply experienced with multi-channel Swiss programming.
The convertible guide bushing system handles both Swiss-mode for long parts and guide-bushless operation for shorter work. Note that several specifications are estimated from related B012x and BW12x models, as Tsugami doesn't publish complete standalone specifications for the B0128W. The estimated dimensions of 2,010 x 1,505 x 1,750 mm and weight of 2,900 kg align with the BW series machines that share the independent opposed tool post architecture.

Strengths & Limitations
Strengths
- Independent opposed tool posts plus back tool post Y-axis enables diverse simultaneous processing on 12 mm parts
- 9-axis 3-path simultaneous control maximizes cycle time reduction on complex small parts
- 12,000 RPM main and sub spindle speeds are excellent for small-diameter precision work
- Live tooling at 8,000 RPM enables cross-drilling and milling without secondary operations
- Modular tooling system allows optimal tool allocation for different part geometries
- Automatic programming software comes standard, reducing multi-channel programming complexity
Limitations
- Several specifications are estimated from related models — confirm with your Tsugami distributor
- 1.5/2.2 kW spindle motor limits heavy cutting on harder materials at larger diameters
- 9-axis programming complexity requires skilled operators and capable CAM software
- 12 mm bar capacity restricts the machine to small parts only
- Premium pricing over standard B0125/B0126 gang tool post models

Frequently Asked Questions
01
The W suffix indicates independent opposed tool post design. Standard B012x models (like the B0125, B0126) use conventional gang tool posts. The W variant adds independent opposed posts that index separately, reducing non-cutting time between operations. It's a fundamentally different tool post architecture.
02
Both are 9-axis 12 mm machines with independent opposed tool posts, but they're different models in Tsugami's lineup. The B0128W specifically combines independent opposed posts with a back tool post Y-axis and includes modular tooling capability. The BW128Z-II has Z-axis movement on the rear tool post. They target similar applications but with different tool post configurations.
03
Several B0128W specifications are estimated from related B012x and BW12x models. The bar capacity (12 mm), axis count (9), spindle speeds (12,000 RPM), and motor power (1.5/2.2 kW) are confirmed from the product page. Dimensions, weight, tool capacity, and rapid traverse are estimated. Contact Tsugami for confirmed specifications before purchase.
04
Modular tooling on the B0128W means you can reconfigure tool positions and types within the opposed tool posts without replacing the entire post assembly. This enables optimal tool allocation for different part geometries — you can set up the tool posts differently for each job without the cost and time of complete post changes.
