Swiss Machined Parts: Product Overview
Swiss machined parts are precision turned components produced on Swiss-type CNC machines.
- Guide-bushing support for Swiss turningMaterial held close to the cut, minimising deflection on small-diameter Swiss turned parts.
- Precision Swiss CNC componentsTolerances down to ±0.005 mm across repeat production, depending on geometry and material.
- Multi-feature Swiss machined partsThreads, grooves, cross-holes and flats can be completed in one cycle without re-fixturing.
- Long L/D ratio componentsIdeal for slender shafts, pins and other turned components that challenge conventional lathes.
Why CNCPioneer for Swiss Machined Parts?
Coordinate geometry, material, finishing and inspection around the part's intended function.
High length-to-diameter ratio
Slender shafts or pins where L/D > 3:1 — guide-bushing support keeps the part stable at the cutting point, preventing deflection.
Tight tolerances required
Applications demanding ±0.005 mm or tighter on diameter, runout or position, subject to engineering review and feature geometry.
Multiple features on one part
Parts with threads, grooves, cross-holes, or flats that would need re-fixturing on a conventional lathe — completed in a single cycle here.
High repeatability across batches
OEM components where dimensional consistency from piece to piece and batch to batch is critical to downstream assembly.
Difficult-to-hold materials
Brass, stainless, titanium, or free-machining alloys where chip control and surface finish are harder to manage at small diameters.
