What Is Swiss CNC Machining?
Swiss-type CNC machining feeds bar stock through a guide bushing so cutting occurs close to the support point. This configuration helps control deflection while producing small, slender, and complex components.
CAM software converts the STEP model into toolpaths. Depending on the machine configuration, the main spindle, sub-spindle, and live tools can coordinate turning, drilling, threading, and milling operations.
The process is especially useful for small-diameter parts with a high length-to-diameter ratio. Common applications include medical components, aerospace fasteners, connector pins, valve needles, and precision shafts.
Swiss-Type CNC
Machine Configurations
Machine configuration determines which turned, drilled, threaded, and milled features can be completed in a coordinated setup. The appropriate setup depends on part geometry and production requirements.
Bar stock advances through a guide bushing while cutting takes place close to the support point, helping control deflection in long, slender parts.
A sub-spindle and live tooling can machine back-side and milled features within a coordinated workflow, reducing secondary setups.

Design Tips for Swiss CNC Machining
Use these guidelines to improve manufacturability and reduce unnecessary setup and machining cost.
Avoid Deep, Narrow Pockets
Deep narrow features can cause tool deflection and chatter. Keep depth-to-width ratios practical where possible.
Add Radii to Internal Corners
Round cutting tools cannot create perfectly sharp internal corners. Use a practical internal radius.
Avoid Unnecessarily Tight Tolerances
Apply tight tolerances only to functionally critical dimensions and use a suitable general tolerance elsewhere.
Use Standard Hole Sizes
Standard drill and thread sizes use readily available tooling and can reduce setup time and cost.
Avoid Very Thin Walls
Thin walls can deflect during machining. Maintain practical wall thickness for the selected material and geometry.
Define Datum Surfaces
Clearly identify datum and setup references on the technical drawing.
