Tsugami B0386-II

The Tsugami B0386-II is a 6-axis CNC Swiss-type automatic lathe with 38mm bar capacity, representing Tsugami's large-diameter Swiss offering for manufacturers producing medium-to-large diameter precision parts in the medical, aerospace, and hydraulic sectors. The 38mm capacity positions the B0386-II at the upper limit of Swiss-type bar diameter, covering applications — orthopedic implant blanks, aerospace structural fittings, hydraulic manifold bodies — where the Swiss-type architecture's single-setup complete machining advantage is required at diameters that exceed the 32mm limit of most Swiss-type platforms. Tsugami, part of the Precision Machinery Group and one of Japan's most established Swiss-type lathe manufacturers, brings engineering depth and production volume to the B0386-II that supports long-term parts availability and field service reliability.

The B0386-II's 6-axis simultaneous control provides the main spindle Z-axis, front and back cross slides, driven tool axes, and back spindle control needed for complete part machining from bar. At 38mm diameter, the B0386-II's structural design — headstock, guide bushing assembly, and tool slides — is scaled for the cutting loads associated with aggressive stock removal in stainless steel, titanium, and cobalt-chrome at this diameter. Tsugami's approach to the large-diameter Swiss platform focuses on structural rigidity and thermal management: at 38mm, temperature-driven dimensional drift during extended production runs is a greater concern than at smaller diameters, and Tsugami addresses this with comprehensive thermal compensation strategies.

The II-generation designation reflects Tsugami's iterative refinement of the B0386 platform. The B0386-II incorporates improvements in control integration, guide bushing precision, and driven tool performance compared to the original B0386, based on customer feedback from demanding medical and aerospace production environments. Tsugami's global distribution network through Marubeni Citizen-Cincom in North America ensures that North American customers have access to applications engineering support, spare parts, and qualified service technicians for the B0386-II.

For manufacturers producing large-diameter precision parts in low-to-medium volumes where single-setup complete machining from bar is commercially essential — orthopedic hip stems, aerospace actuator housings, fluid power valve bodies — the Tsugami B0386-II delivers the Swiss-type advantage at the 38mm diameter range. Tsugami's global installed base of Swiss-type equipment means that application knowledge, tooling optimization experience, and programming best practices for the B0386-II are well-documented and accessible through the distribution network.
