Tsugami HE10J

The Tsugami HE10J is a 10mm capacity micro Swiss-type sliding headstock CNC lathe purpose-built for the smallest and most precise bar work applications. Operating at the extreme fine end of the Swiss-type spectrum, the HE10J targets the production of miniature precision components for the watch and clock industry, medical micro-devices, micro-electronics, and scientific instrumentation — markets where part diameters routinely fall below 5mm and tolerances are measured in fractions of a micron.

At 10mm maximum bar capacity, the HE10J's spindle system is optimized for very high rotational speeds — well beyond what a 32mm-class machine can offer — enabling practical surface speeds on tiny-diameter workpieces without sacrificing surface finish. The machine's thermal stability systems are particularly critical at this scale: even minor temperature gradients in the main spindle or guide bushing translate directly into dimensional variation. Tsugami addresses this with a thermally symmetric column design and oil-cooled spindle bearing arrangement.

Tooling on the HE10J is configured for fine work: gang slides carry precision ground turning tools, boring bars, and cross-drilling units scaled to the micro diameter range. Driven tool capability supports milling and cross-drilling, enabling complete machining of micro-components with flat faces, cross holes, and complex end features. The guide bushing is precision-ground to match bar diameter with minimal clearance, providing the support necessary to hold tolerances on slender workpieces.

For watchmaking components — balance wheels, pivot arbors, escapement parts — and medical micro-device components such as cannula fittings and endoscopic tool bodies, the HE10J occupies a specialized niche where very few machines compete. Tsugami's decades of experience in micro precision machining are encoded in the HE10J's design choices, making it a trusted platform in dedicated micro-machining facilities worldwide.
