Benefits for Metal Cutting Manufacturers

The SA(PYII) Series enables manufacturers to achieve exceptional accuracy, faster cycle times, and reduced material waste—all while maintaining process stability for continuous, high-volume production.

  • Enhanced accuracy and rigidity – Dual Y-axis design provides independent control for simultaneous operations on both spindles, ensuring high accuracy and balanced cutting forces.
  • Faster throughput – High-speed rapid traverse up to 1,260 IPM and overlapping front and back machining dramatically reduce cycle times.
  • Superior surface finishes – Servo learning oscillation option delivers consistent chip control and improved finish on stainless steel, titanium, and hard-to-machine alloys.
  • Flexible machining capability – Exchangeable rotary guide bushing system easily converts to non-guide mode in about 45 minutes, minimizing remnant length and reducing material costs when machining short parts or non-ground barstock.
  • High-performance drive system – Built-in motor spindles and precision-preloaded ballscrews deliver smooth, stable rotation and high repeatability across all axes.
  • Reliable long-term performance – Constructed with top-tier components including NSK ballscrews, THK linear guideways, FAG and NSK bearings, and Mayr couplings for long life and consistent results.
  • Automation ready – Compatible with TRACER bar feeders, OB7 and FANUC CRX collaborative robots, and Mitsubishi LoadMate Plusâ„¢ robotic systems for lights-out production.

Ideal Cutting Applications

  • Medical: Bone screws, dental implants, orthopedic pins, and surgical fittings
  • Aerospace & Defense: Connectors, shafts, actuators, fasteners, and precision housings
  • Automotive: Valves, transmission pins, sensor components, and fuel system fittings
  • Electronics: RF connectors, terminals, miniature fasteners, and couplings
  • General Production Turning: Tight-tolerance small parts requiring superior finish quality and precision

FAQs

When should a shop consider buying a CNC Swiss lathe?

If your shop runs high volume parts and needs the ability to run lights out, then a Swiss lathe may be a great option. Changeover on a Swiss lathe is minimal, especially when running a family group of similar style parts together. With the exception of changing out collets, an operator can load a new program and start cutting in typically a few hours at the most. Components machined on a Swiss lathe are also more reliably turned than with a conventional lathe and can therefore meet high accuracy specifications. This increased accuracy means that switching to a Swiss from a conventional lathe can reduce costs related to returned parts as well as delayed lead time and retooling costs.

What if I don’t want to use a guide bushing on a Swiss lathe?

The rigidity offered by the guide bushing makes it one of the best attributes of a Swiss lathe. If a shop doesn’t see the need for the guide bushing, then they are better off buying a conventional lathe for less money.

How many axes does a CNC Swiss lathe have?

The number of axes varies depending on the options. For instance, the SA(PYII) features a total of 8 axes (Z1, X1, Y1, Z2, X2, Y2, C1, and C2). Nexturn, and other brands of Swiss lathes, have options for a Y axis on the backside. Other models also have B-axes for use with angular drilling tools. Most conventional Swiss machines have anywhere from 7-9 axes.

What applications and industries are Swiss lathes best suited for?

Swiss machining has become the process of choice for a wide range of applications and industries that require accuracy, quick production times, and a reduction in variable costs. This includes turning applications with live tooling for cross-holes using milling, drilling, and or tapping, as well as parts that require high precision in high volume. Industries that require high precision metal machining include aerospace, defense, electronics, medical, and automotive.
