What Is Quality Assurance in CNC Machining?
Machine to Spec
Parts are CNC machined to your drawing tolerances using calibrated equipment and verified toolpaths.
CMM Inspect
Every critical dimension is measured on our CMM. Actual values are compared to nominal specs.
Document & Ship
Inspection reports, material certs, and conformance documents ship with your parts.
Built-In Quality on Every Order
Most shops charge extra for inspection. We include it as standard — because shipping uninspected parts is not an option.
CMM on Every Order
Every order gets CMM inspection before shipping. We measure critical dimensions and compare actual values to your drawing tolerances. No exceptions, no extra charge.
NIST-Traceable Equipment
Our CMM and gauges are calibrated to NIST-traceable standards. Measurement accuracy to ±0.0001". Your quality team can trust the numbers.
Full Documentation
Dimensional inspection reports, material certs with heat lot traceability, first article reports, and certificates of conformance. Everything ships with your parts.
Industry-Specific Compliance
We support aerospace, defense, medical, and automotive documentation requirements. AS9100-style records, FAI reports, and MIL-STD-ready paperwork available.
Quality Assurance Services
From first article inspection to surface roughness testing — every measurement documented and traceable.
CMM Inspection
Full 3D coordinate measurement of critical dimensions, hole positions, angles, and geometric features. Every measurement compared to your drawing tolerances.
±0.0001" accuracyFirst Article Inspection (FAI)
Complete measurement of the first part from every production run. Detailed report with actual vs. nominal values for every ballooned dimension. You approve before we continue.
Full balloon reportGD&T Verification
Flatness, parallelism, perpendicularity, position, runout, concentricity, and true position. If your drawing calls it out, we measure and report it.
All GD&T calloutsMaterial Certifications
Every metal order ships with a mill cert proving alloy, heat lot, and chemical composition. Full traceability from raw stock to finished part.
Heat lot traceabilitySurface Roughness Testing
Profilometer measurement of surface finish (Ra values). Verify mating surfaces, sealing faces, and cosmetic requirements meet your spec.
Ra measurementCertificate of Conformance
Formal documentation stating that parts conform to purchase order specifications. Supports receiving inspection and quality system requirements.
