CNC-turned contact pins and terminals
Pins, terminals and bushings turned from bar and measured against one datum.
Products · Metal parts
Rings, collars and spacer sets in stainless and aluminium, bored and faced from one datum so the stack closes without shims.

Two numbers decide whether a ring works: how far the bore sits off the flange centre, and how parallel the faces stay once the part is clamped. Thin walls move under clamping force, so the sequence carries the result — rough out, stress-relieve where the section is thin, then finish bore and both faces in one setup on a 0.001 mm turning centre.
Most of these parts disappear inside an assembly: bearing spacers, clamp collars, sensor barrels. We fix the datum scheme and the inspection points with you at DFM stage, which is why the first-off report lists the same features your assembly gauges touch, not a generic checklist.
Specification
Standing capability for ring and spacer work. Datum scheme and inspection points are confirmed with you before the first setup.
| Manufacturing route | Turning and milling centres, drilled and tapped holes; wire-cut and sinker EDM for die components |
| Stock | Stainless steel, aluminium, brass and copper alloys, titanium |
| Concentricity | Bore and flange held from one datum, checked on the CMM |
| Drawing tolerance | ±0.01 mm on critical features; machine resolution 0.001 mm |
| Distortion control | Rough, stress-relieve on thin walls, then finish in a single setup |
| Finish | As machined, bead blast or polish; plating and anodising to your specification |
| Verification | First-off measured on the Swiss Hexagon CMM; the report travels with the batch |
| Paperwork | 2D/3D drawings, material certificate, inspection report |
Figures are our standing capability for this class of work, not a quotation for a specific job. Material, finish and inspection plan are agreed on the drawing before cutting starts.

Next step
2D drawing or 3D model, the alloy and the quantity are enough for a price, a lead time and the points we would change before cutting metal.
