Coil-fed Swiss Turning

What is Coil-Fed Swiss Turning?

Coil-fed Swiss turning is a highly efficient machining process designed for mass-producing small, precision parts. Unlike a standard CNC lathe where the material (bar stock) rotates, in this process, the material is fed linearly from a coil while the cutting tools driven by mechanical cams, rotate around it.

Micron’s coil-fed Swiss machines dedicated, non-stop production line for miniature components, capable of finishing a completed part every few seconds.

The Swiss Turning Advantage: Why Choose This Method?

When your project fits the profile, coil-fed Swiss turning offers distinct benefits that other machining processes can’t match.

  • Large Batch Speed & Efficiency: With cycle times often measured in seconds, this is one of the fastest production methods available for small-diameter parts. The continuous coil feed minimizes downtime, making it ideal for runs of 50,000 parts or more.
  • Exceptional Precision & Repeatability: The cam-driven system and non-rotating material bar eliminate vibration and runout at such small scales. This results in incredibly tight tolerances and consistent quality across every single part in a production run.
  • Versatility in Miniaturization: Don’t let the small size fool you. These machines can create intricate features with remarkable accuracy, including:
    • Threads (internal and external)
    • Knurling
    • Tapers and complex profiles
    • Precise grooves and undercuts
