Can Your CNC Parts Pass Compliance Without Material Certs?

Your CNC parts are finished, but the material certificates are missing. At that point, shipment and compliance approval are at risk, even if the parts meet all dimensional requirements. Most CNC parts cannot pass compliance without material certificates. Only limited cases allow recovery, and testing alone does not replace traceability under most audit or customer […]

Your Critical Dimensions Are Wrong — What Happened?

Your parts arrived with a critical dimension out of spec, even though the supplier claims they were inspected. This usually happens because the dimension was never properly inspected — not because machining failed. Missing first-article checks, undefined datums, or skipped measurement steps allow parts to pass inspection but fail assembly. Read on to see what […]

Your Parts Have Wrong Surface Roughness — What Happened?

Your CNC parts passed dimensional inspection, but surface roughness failed. This usually happens after machining is already complete, leaving you with finished parts that can’t be assembled, coated, or approved—yet no clear explanation from the supplier. Wrong surface roughness almost always results from missing or incorrect process control, not unclear drawings. Typical causes include the […]

Your Coating Finish Failed — Supplier or Process Problem?

Your coating finish failed — peeling, discoloration, blocked threads, or post-coat dimensions out of tolerance. When this happens, suppliers often blame “finish risk” or material choice, leaving you uncertain where the failure actually came from. Most coating failures are caused by supplier process control breakdowns, not material or design flaws. If prep, masking, fixturing, bath […]
