Nexturn SA(XIII) Series – 11-Axis, 3 Channels & 3 Y-Axes Swiss Lathes
The Nexturn SA(XIII) Series includes two high-performance models โ the SA-32XIII (1.26โ / 32 mm) and SA-38XIII (1.50โ / 38 mm) โ each engineered with 11 axes, a 3-channel dual opposed gang tool post, and three independent Y-axes for advanced multi-tool synchronization.
These precision CNC automatic lathes feature a 33-tool capacity, exchangeable rotary guide bushings, and modular rotary spindles, providing unmatched flexibility for both long and short-part machining. Built for manufacturers in medical, aerospace & defense, automotive, electronics, and general precision part production, the SA(XIII) Series delivers ultra-accurate, high-speed performance that competes head-to-head with leading brands such as Marubeni Citizen-Cincom, Star, Tornos, Hanwha, Swiss-Tech, Swissturn, Mazak, and Doosan.

Benefits for Metal Cutting Manufacturers
The SA(XIII) Series is purpose-built for manufacturers who demand maximum productivity, precision, and process flexibility. Its 3-channel control and triple Y-axis configuration enable up to three tools to cut simultaneously on different planes โ dramatically reducing non-cut time while optimizing tool utilization and cycle efficiency. The machineโs one-piece FEM-analyzed cast-iron base ensures outstanding rigidity, vibration damping, and long-term accuracy under heavy cutting conditions.
With built-in motor spindles on both main and sub stations reaching 8000 RPM, and full C-axis control at 0.001ยฐ positioning, the SA(XIII) performs complex milling and turning operations in a single setup. Pre-tensioned ballscrews, THK linear guideways, and servo learning oscillation contribute to superior motion control, chip management, and surface integrity. Together, these technologies provide high-precision, high-speed machining performance, achieving cycle time reductions up to 30% compared to conventional Swiss-type lathes.
Ideal Cutting Applications
- Precision medical components (bone screws, cannulas, orthopedic pins)
- Aerospace fasteners, sensor housings, and hydraulic fittings
- Automotive connectors, shafts, and precision valve components
- Miniature electronic parts requiring multi-axis milling and fine turning
- High-volume small-part production where simultaneous front/back machining boosts throughput
