Swiss CNC Machining

Swiss CNC Machining Services for Precision Turned Parts

Avanti Engineering, Inc. specializes in Swiss CNC machining — also known as Swiss screw machining — for the production of high-precision, small-diameter components with tight tolerances. Using advanced sliding-headstock technology and multi-axis CNC controls, we deliver complex turned parts with exceptional accuracy, consistency, and surface finish.

Whether you’re manufacturing thousands of intricate parts or sourcing reliable production for high-precision cylindrical components, Avanti is your trusted partner for Swiss-type machining at scale.

What Is Swiss CNC Machining?

Swiss CNC machining is a type of precision turning that uses a sliding headstock and a guide bushing to support the workpiece close to the cutting tool. This setup minimizes deflection, enabling extremely tight tolerances (as low as ±0.0002″) and smooth finishes — even on slender or complex parts.

Originally developed for the watchmaking industry, Swiss-type machining is now widely used in medical, aerospace, electronics, and fluid control applications.

At Avanti, we combine this high-precision process with CNC control, live tooling, and automated bar feeding to streamline production of custom components with repeatable quality.

Swiss CNC Machining Capabilities

Our Swiss machines are equipped with multi-axis control, live tooling, and high-speed bar feeders for unattended operation — ideal for high-volume runs of complex parts.

🛠 Core Capabilities:

• Turning diameters as small as 0.125”
• Tolerances to ±0.0005”
• Multi-axis machining (up to 9-axis)
• Live tooling for milling, drilling, cross-tapping, slotting, and more
• Automatic bar feeders for continuous production
• Complex geometries and multiple features machined in a single cycle

Advantages of Swiss CNC Machining
