Tight tolerances are a process discipline, not a machine brochure spec. Thermal stability, fixturing, tool wear control and measurement strategy all have to agree — and then the result has to be proven, on a CMM, not assumed.
±0.005 mm typical where applicable, ±0.01 mm standard on simultaneous 5-axis — stated per feature, per drawing.
Zeiss CMM inspection with dimensional reports on critical features, batch after batch.
Our engineers flag tolerance stacks and measurement risks during DFM — before they become scrap.
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Typical tolerance | ±0.005 mm typical (3-axis) · ±0.01 mm standard (simultaneous 5-axis) |
| Surface finish | Down to Ra 0.2 µm |
| Measurement | Zeiss CMM with documented dimensional reports |
| First article | Full first-article inspection before series release |
| Material verification | Spectrometer chemistry check against EN/DIN grades |
| Certificates | EN 10204 3.1 on request |
| Prototype lead time | Typically 5–10 working days |
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Kitted, ESD-safe or cleanroom packaging, with local engineering and after-sales support through our German partner.
