Quality & Tolerances — Inspection, Taper Control, First Article

How we hold tolerance

Waterjet is repeatable; the discipline is in nesting, speed and head angle.

Parameter	Five-axis	Three-axis
Committed cutting tolerance	±0.10 mm	±0.15 mm
Machine repeat positioning	±0.025 mm	±0.025 mm
Taper control	Head tilts to neutralise taper	Standard taper; edge class selectable

Inspection process

1 · Nesting & speed review

Before cutting, the engineer sets cutting speed and path per material/thickness to hit the tolerance you asked for.

2 · First-article check

On batch jobs we cut and measure a first piece; photo and key dimensions on request before the run continues.

3 · In-process monitoring

Abrasive flow, pressure and path are watched during the run; deviations trigger a re-check.

4 · Final QA & dimensional report

Finished parts inspected against the drawing. A dimensional report can be supplied on request.

Tell us the tolerance that matters. If a feature is fit-critical we cut it premium-grade; if it is hidden structure we cut standard and save you cost. Detail on the drawing drives the price.

Honest limits

So your QA team knows what to expect.

Waterjet leaves a slight natural taper on thick parts unless 5-axis compensation is specified — state edge-class need on the RFQ.
Very tight tolerances (< ±0.10 mm) on thick exotic stock may need a finishing pass or a different process; we will say so.
We cut to drawing. We do not certify material mill reports unless you supply them or request sourcing with certs (quoted separately).
