Quality Control for CNC Machined Parts
From drawing review to final checks, inspection requirements guide the machining process. We review critical features, material and finish specifications for CNC milled and turned parts, with measurement methods and reporting agreed for each project.

Inspection from Drawing Review to Shipment
A shared inspection plan helps keep drawing revisions, critical dimensions and acceptance criteria aligned throughout the order.
01 / Define Critical Requirements
Review material grade, drawing revision, datums, tolerances, threads and surface requirements. Identify functional fits and agree on the features, methods and sampling needed for acceptance.
02 / Check During Machining
Check agreed key features during setup and machining. Where inspection identifies a deviation, review the cause and any necessary correction before continuing the affected work.
03 / Final Checks & Packing
Review finished parts against the agreed inspection scope, including dimensions and specified finish requirements. Confirm identification, protective packaging and any inspection documents before shipment.
Inspection Requirements & Reports
What should the drawing specify?
Provide a dimensioned 2D drawing with revision, units, datums, critical tolerances, thread specifications and surface roughness. Include a 3D model where available, and highlight features that affect assembly or function.
Can I request inspection documents?
Specify dimensional reports, material certificates, finish certificates or first-article inspection needs during quotation. Availability, format, traceability and any additional cost must be confirmed for the order; documents are not assumed to be included.
Is every dimension checked on every part?
The inspection plan is agreed for each project. Tell us if you require 100% inspection, a defined sampling plan or customer-specific acceptance criteria. We review feasibility and quote the required scope before production.
