When to Choose Swiss Machining
Swiss machining is often selected for small, slender and high-precision parts that are difficult to machine consistently with conventional CNC turning. The guide bushing supports the workpiece close to the cutting tool, helping reduce deflection and improve stability for long or small-diameter components.
Large-diameter shafts may be better suited for CNC turning service. Flat or prismatic parts should usually be reviewed for CNC milling service.
Choose Swiss machining when
The part is small, slender, thread-dense, feature-rich or requires repeatable diameter control.
Choose CNC turning when
The part is larger, less slender or does not need guide-bushing support.
Review carefully when
The part has deep grooves, very small threads, burr-sensitive edges or strict length-to-diameter ratio concerns.
Ask for DFM review when
You are unsure whether Swiss machining or conventional turning is more cost-effective.
Process Comparison
Swiss Machining vs CNC Turning
Swiss machining is not simply “more precise turning.” It is most valuable when part size, length-to-diameter ratio, feature density or production repeatability make conventional turning less stable or less efficient.

DFM Guidance
Design Tips for Swiss Machined Parts
For Swiss machined parts, manufacturability depends on diameter, length-to-diameter ratio, thread specification, groove geometry, burr control and inspection notes. A 2D drawing is strongly recommended when threads, tolerances or functional fits matter.
- Clearly define critical OD and ID dimensions.
- Review long slender parts for deflection risk.
- Specify thread type, pitch, depth and tolerance.
- Avoid overly deep or narrow grooves when design allows.
- Mark functional edges and surfaces that require burr control.
- Apply tight tolerances only to functional features.
For broader pricing factors, review CNC machining cost.
Your questions answered
Swiss Machining FAQs
When should I choose Swiss machining?
Swiss machining is recommended for small-diameter, slender or high-precision turned parts that require stable support, tight diameter control and repeatable production.
What is the difference between Swiss machining and CNC turning?
In conventional CNC turning, the workpiece is held in a chuck. In Swiss machining, the bar stock is supported close to the cutting tool, which can improve stability for small and slender parts.
Can Swiss machining reduce deflection on long slender parts?
Yes. Because the workpiece is supported close to the cutting point, Swiss machining can help reduce deflection for small-diameter and long slender components.
What parts are best suited for Swiss machining?
Swiss machining is well suited for precision pins, micro shafts, small bushings, spacers, threaded inserts, connectors, fittings and miniature turned components.
Can you machine small threaded components?
Yes. Small external and internal threads can be reviewed from your drawing. Please specify thread type, pitch, depth and tolerance requirements.
What materials can be Swiss machined?
Common materials include stainless steel, brass, aluminum, copper, titanium and engineering plastics such as PEEK, POM, nylon and PTFE.
Can you support repeat production?
Yes. Swiss machining is suitable for repeat production when part geometry, material and quantity fit the process.
Do I need a 2D drawing for Swiss machined parts?
A 3D CAD file is helpful, and a 2D drawing is strongly recommended for tight tolerances, threads, grooves, surface finish and inspection requirements.
Can you inspect small Swiss machined parts?
Yes. OD, ID, thread, groove, length and fit-related features can be inspected with suitable gauges and measuring tools. Inspection reports are available upon request.
Can you sign an NDA before reviewing files?
Yes. NDA can be arranged before file review when your project requires confidentiality.
