Swiss-Type Machining for Small-Diameter Precision Components

Long, thin, delicate turned parts are where Swiss-type machining earns its keep. Material feeds through a guide bushing so the cut always happens next to the support — keeping small diameters accurate, straight and beautifully finished.

How we work

From Drawing to Delivered Part

A transparent, engineering-led process built for long-term supply programs — not one-off transactions.

1

Submit & Review

Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.

2

Quote & Material Plan

You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.

3

Machine & Inspect

In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.

4

Deliver & Support

Kitted, ESD-safe or cleanroom packaging, with local engineering and after-sales support through our German partner.

FAQ

Frequently asked questions

Small-diameter, high-precision turned parts — especially long, slender components that would deflect in conventional turning. The guide bushing supports the material right at the cutting zone.
Ø 0.5–20 mm. For larger round parts, our conventional CNC turning covers Ø 2–65 mm.
Yes — ±0.005 mm typical where applicable, verified on our Zeiss CMM with documented reports per batch.
