CMM Inspection for CNC Components
A tolerance on a drawing is a promise. A CMM is how you prove it was kept. Every dimension on your parts is measured with the instrument suited to it — and the result is documented, not asserted.
Why equipment manufacturers choose us
Measured in-house, on a Zeiss CMM for geometry and position, the TRIMOS V5 height gauge for heights and steps, and the AI-Vision system for fine features
No outsourced inspection, no waiting on third-party reports — dimensional verification happens where the parts are made.
Reports you can file
Dimensional inspection reports per batch, tied to your part number and revision.
Geometry, not just size
Diameters, positions, concentricity and geometric relationships — checked against your drawing, not against a sample.
CMM Inspection
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Equipment | Zeiss coordinate measuring machine (in-house) |
| Scope | Critical dimensions and geometric features per drawing |
| Typical tolerance verified | ±0.005 mm typical · ±0.01 mm standard, feature-dependent |
| Documentation | Dimensional inspection reports per batch |
| Program stages | First-article layout · in-process · final batch inspection |
| Complementary checks | Material spectrometer verification · EN 10204 3.1 certificates |
| Quality system | ISO 9001:2015 (GICG) |
Materials we machine
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
Micro and fine-feature precision work
Below are examples of this kind of work held to our standard tolerance and finish. Dimensions, drawings and material certificates are available on request.
