Tornos SwissNano 4

The Tornos SwissNano 4 is the definitive ultra-micro Swiss-type automatic lathe for parts up to 4mm in diameter, engineered to the extreme precision tolerances of watchmaking, micro-mechanics, and microfabrication markets where no other production platform can match its capability. Tornos, the Swiss manufacturer with the longest continuous history in Swiss-type automatic lathe design, developed the SwissNano specifically for the sub-4mm range—a market segment defined by horological components, miniature medical devices, and precision micro-instruments where conventional Swiss-type machines are simply too large to achieve the required accuracy at the required scale.

The SwissNano 4 is the smallest production Swiss-type machine from any major manufacturer. Its entire machine architecture—from thermal stability management to spindle bearing selection to the micrometric adjustment systems—is optimized for sub-millimeter feature production. Dimensional tolerances of a few microns, surface finishes in the Ra 0.1 range, and feature-to-feature relationships of sub-micron repeatability are achievable in production on the SwissNano 4. These specifications are not achievable on conventional Swiss-type machines even when machining within their bar capacity; the SwissNano's dedicated micro-precision architecture is what enables production at this scale.

The SwissNano 4 carries a particularly strong identity in the Swiss and European watchmaking industry, where it is used for movement components including balance wheel pivots, pallet fork pins, stem components, and jewel-setting parts that define traditional mechanical watch quality. The machine's Swiss heritage aligns directly with the horological industry's concentration in the Jura region of Switzerland, and Tornos's deep application knowledge in watch component production makes the SwissNano 4 the default choice for new movement component production lines.

For medical applications, the SwissNano 4 addresses the growing demand for minimally invasive device components—guidewire tips, micro-catheter components, cochlear implant parts, and ophthalmic instrument components—where part diameters measured in fractions of a millimeter must be produced with precision far exceeding conventional Swiss-type capability. The machine's TISIS control (Tornos Interactive System for Intelligent Supervision) provides the precision motion coordination and thermal compensation necessary for maintaining micron-level tolerances across production runs.
