Overview
The Tsugami B0326 is a Swiss-type CNC sliding headstock lathe engineered for precision turning and milling of bar stock up to 32 mm in diameter. Tsugami, a Japanese machine tool manufacturer with strong roots in Swiss-type lathe development, designed the B0326 series for demanding production environments where surface finish, dimensional accuracy, and cycle efficiency must be maintained simultaneously across long production runs. The B0326 is widely used in medical, automotive, and electronics component manufacturing.
The B0326 incorporates a high-rigidity headstock and guide bushing system that minimizes workpiece deflection during turning and drilling operations. Tsugami's design philosophy on the B0326 emphasizes structural stability as a foundation for dimensional repeatability — a key consideration in Swiss-type machining where bar stock variations and thermal effects can translate directly into part-to-part diameter variation. The machine's spindle bearings and headstock casting are selected and processed to maintain thermal equilibrium quickly during warmup, reducing the startup scrap rate that affects production efficiency on precision Swiss-turned components.
The B0326 supports simultaneous multi-axis machining through its main spindle, sub-spindle, and multiple live tool stations. Tsugami offers the B0326 in configurations ranging from 7 to 11 axes depending on the optional tooling units specified, supporting complex part geometries including cross-drilled holes, off-center features, milled flats, and threaded features on both faces. The sub-spindle provides full back-working capability with live tooling, enabling complete part machining in a single continuous cycle without secondary operations.
Tsugami's North American distribution is managed through Rem Sales LLC, which provides application engineering support, training, and field service for the B0326 across the United States. The machine uses a FANUC control system, providing compatibility with the broad range of CAM software and post-processors in use at North American precision parts manufacturers. Tsugami's B0326 competes directly with the Citizen Cincom L32, Star SR-32J, and Hanwha XD series in the 32 mm Swiss lathe market, with a reputation for strong value relative to its capability level.

Strengths & Limitations
Strengths
- High-rigidity headstock and guide bushing system designed for dimensional repeatability across long production runs — reduces startup scrap on precision medical and automotive parts
- Competitive pricing in the 32 mm Swiss lathe class provides strong capability per dollar relative to premium Japanese and Swiss competitors
- FANUC control with broad CAM compatibility simplifies programming integration and operator training at North American precision parts facilities
- Tsugami / Rem Sales North American support network provides application engineering, training, and field service coverage
Limitations
- Sub-spindle speed (8,000 rpm) is lower than the main spindle — high-speed back-working on small features may be constrained relative to machines with dual 10,000 rpm spindles
- Less widespread brand recognition in North America compared to Citizen and Star, which can affect resale value and operator familiarity
- Maximum live tool speed of 6,000 rpm limits high-speed milling capability compared to higher-speed optional spindles available on competing models

Frequently Asked Questions
01
The B0326 supports bar stock up to 32 mm (1.26 inches) in diameter. This 32 mm capacity is the standard for the mid-range Swiss lathe market and covers the most common precision turned component diameters in medical, automotive, and electronics applications. Smaller bar diameters can be run with appropriate collets and guide bushing configurations.
02
Tsugami machines are distributed in North America through Rem Sales LLC, which has an established network of application engineers, sales representatives, and field service technicians covering the United States. Rem Sales provides machine demonstrations, application support, tooling setup assistance, and spare parts for the B0326 and other Tsugami Swiss-type lathes.
03
Both machines are capable 32 mm Swiss-type lathes with FANUC or proprietary controls, guide bushing support, and multi-axis live tool capability. The Citizen L32 is distinguished by its LFV chip-breaking technology, which provides automatic chip control in titanium and other difficult materials, and carries a higher price point. The Tsugami B0326 offers competitive structural rigidity and dimensional accuracy at a lower acquisition cost, making it attractive for shops where LFV chip control is not a primary requirement. Selection typically depends on specific material requirements and budget.
