FAQs
Why do they call it a Swiss?
Pretty much the reason you would think โ the Swiss lathe originated in Switzerland! First used to make fine threaded parts and small shafts for the Swiss watch industry, the machines were later used to make intricate gun parts. However, those early nineteenth century watchmakers would hardly recognize the CNC Swiss machines of today. The early machines utilized a disc cam to rotate tooling to a workpiece, which was held in place by a collet and supported by a guide bushing. Disc cams moved the tools in a radial motion while simultaneously altering the headstock position. Swiss machines improved by leaps and bounds in the 1970s, with computer numerical controls (CNC) replacing cams.
When is it worth it to buy a Swiss lathe?
A Swiss lathe is a great option for shops that run high volume parts and need lights-out capabilities. Changeover on a Swiss lathe is minimal, especially when running a family group of similar style parts together. Another benefit is that Swiss machining is able to produce parts to high accuracy specifications, which means reduced costs from returned parts.
Why is the Swiss machine tooling capacity significant?
CNC Swiss machines can accommodate 20 or more tools in the tool zone, many with live tooling. When combined with a sub-spindle and backworking stations, this array of tools can virtually eliminate the need for secondary operations on complex parts, allowing Swiss machines to produce finished, ready-to-ship components.
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
