Swiss Lathes (also known as swiss machines, swiss-type turning machines, and sliding headstock machines) were originally designed for “long and skinny” parts (typically 6:1 length to diameter ratio or larger). The principle behind the swiss machine is that the bar moves to the tool rather than the tool moving to the bar (in the Z direction). This vastly reduces the amount of deflection during precision swiss machining since the cutting action occurs closer to the guide bushing. E.J. Basler has the capabilities to machine various material grades including red metals, 303, 304, and 316 stainless steel, and aluminum.

Benefits of Swiss Screw Machining

Generally, Swiss Machines have one or two spindles. This allows the Swiss Machining lathes to be fast and efficient in creating custom parts – some in as little as 10-15 seconds. This makes them great for large production runs on small-diameter parts.

As swiss-style lathes have improved in technology and speed, many non-typical Swiss-type parts can be run completely on these machines (in cases where it would take 4-5 operations in the past).

Typical tolerance ranges are in the +/-.0005” (+/-.013mm) range depending on the application.  With 11-Axis control, twin turrets, and 4-axis back working, Precision Swiss Turning can handle the most complex precision parts with speed and accuracy.

Advantages of Swiss Screw Machining

  • Extended length to diameter ratio
  • Ability to take on a wider range of bids
  • Additive manufacturing for prototyping and fixturing available
  • Automated inspection equipment unique to your part available with in house automation team
  • PPAP compliant for all your capability study needs
  • FMEA used throughout the manufacturing system – from inspection to shipment

Swiss Machining Design Considerations

  • Ability to machine smaller & more complex parts
  • Ability to perform both turning & milling
  • Reduced cycle times
  • Greater potential for single-process machining
  • Extended length to diameter ratio
  • Ability to take on a wider range of bids
