Overview
The Tsugami B0316-II is a 31.75mm (1-1/4 inch) Swiss-type sliding headstock CNC lathe built for high-precision bar work in the upper tier of the Swiss-type diameter range. Tsugami's BO-series II generation introduced reinforced ribbed cast iron construction and improved thermal stability systems, making the B0316-II a reliable production platform for demanding aerospace, medical, and energy sector components.
Equipped with 16 CNC axes, the B0316-II supports simultaneous machining on the main and sub spindles with extensive driven tool capability. Its layout includes a gang slide for high-speed OD turning, a cross-drilling unit for radial operations, and a back-working turret for complete sub-spindle machining — all programmable for true simultaneous execution to compress cycle times on complex parts.
Tsugami's B0316-II incorporates the Fanuc 32i-B control, a widely adopted platform in precision Swiss machining. The Fanuc ecosystem means compatibility with a broad range of third-party programming and simulation software, and access to a large global base of trained operators and service engineers. High-pressure coolant (up to 1,000 PSI) is available to support chip evacuation in deep-hole drilling and difficult material turning.
The B0316-II is distributed in North America by REM Sales and in Europe by Tsugami's regional partners, with strong application engineering support available for setup and process optimization. For shops already running Tsugami machines, the B0316-II integrates naturally into the existing programming and tooling ecosystem.

Strengths & Limitations
Strengths
- 31.75mm capacity covers a wide range of hydraulic and aerospace component diameters
- 16 CNC axes with simultaneous main and sub-spindle machining for complex complete parts
- Fanuc 32i-B control provides broad software compatibility and large trained operator pool
- High-pressure coolant option supports deep-hole drilling in titanium and Inconel
- Reinforced II-generation cast iron base improves thermal stability for long production runs
Limitations
- Premium pricing reflects the 16-axis complexity — not cost-effective for simple turned parts
- Setup and programming complexity demands experienced Swiss-type technicians
- Larger footprint compared to 20mm-class Swiss lathes requires dedicated floor space allocation

Frequently Asked Questions
01
The B0316-II has a maximum bar capacity of 31.75mm while the B0326-II accommodates up to 32mm (26mm nominal in some configurations). The B0326-II typically offers a larger driven tool count. Both are II-generation platforms sharing the Fanuc 32i-B control architecture.
02
Tsugami offers a GBL configuration option on select B0-series models. The B0316-II's GBL availability should be confirmed with REM Sales or the regional Tsugami distributor, as it depends on part geometry and production volume requirements.
03
Tsugami offers an integrated high-pressure coolant option delivering up to 1,000 PSI through the spindle and driven tool holders. This is particularly effective for drilling deep holes in titanium alloys and for maintaining chip control in austenitic stainless steels.
04
The machine itself has no ITAR classification. Shops producing ITAR-controlled aerospace components are responsible for maintaining appropriate facility certifications and controls. The B0316-II's precision capability (sub-micron repeatability in controlled environments) meets the mechanical requirements for many aerospace parts.
05
REM Sales is the exclusive North American distributor for Tsugami Swiss-type lathes and provides applications engineering, training, and service through a network of regional offices. Field service engineers are available across major manufacturing regions in the US and Canada.
