Swiss-Type CNC Machining for Precision Small Parts
Swiss-type lathes are built for small-diameter parts with high length-to-diameter ratios — exactly the components that chatter or deflect on conventional lathes. Mingchen runs Swiss-type lines for connectors, pins, contacts, inserts and other miniature precision hardware, delivering repeatable geometry part after part at volume.
Why Buyers Choose Swiss-Type Machining
For long, slender or highly detailed small parts, Swiss-type machining holds straightness and dimensional consistency that standard turning cannot match. The guide bushing supports the bar right at the cutting zone, so even parts with extreme length-to-diameter ratios machine without deflection — ideal for repeatable, high-volume programs.
Small Diameters, Long Parts
Guide-bushing support keeps slender parts straight and consistent along their full length.
Repeatable at Volume
Swiss-type lines are scheduled for long-running programs where every piece must match the first one.
Compact Precision Hardware
Electronics connectors, pins, sleeves, fittings and miniature mechanical components.
Typical Swiss-Type Parts
- Connector pins, terminals and contacts
- Long slender pins, axles and probes
- Miniature sleeves, bushings and spacers
- Small threaded and multi-diameter components
- Insert and fitting hardware for assemblies
- Custom non-standard miniature parts from drawing or sample
Materials and Precision
| Aspect | Details |
|---|---|
| Materials | Brass, stainless steel, aluminum, copper alloys and engineering plastics well suited to bar-fed machining |
| Typical precision | Down to ±0.005 mm where the part geometry and material allow |
| Bar-fed production | Continuous bar feeding supports long unattended runs and stable per-piece cost |
| Surface finish | Clean turned finishes with good dimensional consistency across the batch |
| Secondary features | Cross drilling, slotting and milling features where the machine configuration supports them |
| Industries served | Electronics, automotive, machinery and precision custom hardware |
