Used Swiss Lathes

What is a Swiss Lathe?

The lathes for sale here are also known as sliding headstock lathes. As a specialized type of computer numerical control (CNC) machinery, it excels at manufacturing smaller, complex parts.

What Makes a Swiss Lathe Machine Different?

The biggest differentiating factor is the unique setup of these machines. As opposed to a conventional lathe, where the workpiece is fixed in place and the tool moves during operation, Swiss-type equipment uses a sliding headstock to feed the material through a guide bushing.

This way, the cutting tool stays much closer to the material (up to just a few millimetres), providing much better support and precision. This makes Swiss lathes an excellent choice for manufacturing long, thin parts.

Industries Served

These machines can be used in a variety of different industries to produce top-of-the-line components, including:

• Medical: These lathes are a go-to for crafting tiny, intricate components like surgical screws, dental implants, bone pins, and orthopedic device parts.
• Aerospace: Aerospace companies can use these lathes to build precise parts like fittings, fasteners, and hydraulic components.
• Electronics: Connectors, pins, and even housings for electronic devices can consistently be built with Swiss lathes.

The Advantages of a Swiss CNC Lathe

Picking this type of CNC machinery offers a ton of exciting advantages for manufacturing:

• It excels at producing small, complex parts that require small tolerances.
• Swiss-type lathes are ideal for medical devices and watch components, for example.
• They’re highly efficient for high-volume runs as they can minimize cycle times.

What is the Tolerance of a Swiss Lathe?

It depends on the machine, but tolerances typically range from ±0.0001 inches (±0.0025 mm) to ±0.0005 inches (±0.0127 mm).

To maintain these tight tolerances, we recommend:

• Optimizing the guide bushing fit according to the workpiece. If the fit is right, you’ll reduce the risk of scoring the material.
• Use high-quality tooling to minimize chatter and deviation. Swap out older tools regularly.
• Regularly calibrate your CNC system, spindle, and axes to avoid misalignments.
