Drawing and Tolerance Check
We review critical dimensions, tolerance stack-up, thin walls, surface finish, threads, and special notes before quoting or production.
Quality Control Built Around Your Drawing
For custom CNC machined parts, quality starts before cutting metal. XHR reviews drawings, tolerance risks, material requirements, surface finish, assembly fit, and inspection focus before production begins.
First Article Confirmation
First-piece checks help confirm the machining setup before parts move into small-batch or repeat production.
In-Process and Final Inspection
Key features are checked during machining and again before packing, especially dimensions marked as critical on the drawing.
Packing and Delivery Check
Finished parts are protected for shipment with attention to cosmetic surfaces, threaded areas, and customer packing requirements.
Inspection Workflow
A clear workflow makes custom machining easier to manage for overseas buyers and helps reduce surprises after delivery.
Requirement Review
Confirm drawings, material grade, quantity, finish, tolerance level, inspection items, and delivery requirements.
Setup Verification
Check the machining setup, tooling, clamping method, reference surfaces, and first part before batch production.
Dimension Inspection
Measure key dimensions using appropriate tools such as calipers, micrometers, height gauges, gauges, and other inspection methods as required.
Surface and Finish Check
Review burrs, scratches, oxidation, coating, polishing, visible surfaces, and any functional surface treatment requirements.
Final Confirmation
Confirm quantity, critical features, appearance, packing, labels, and shipping details before dispatch.
Feedback Loop
For repeat orders, customer feedback and previous inspection notes are used to keep production expectations consistent.
What Buyers Can Request
Different projects need different levels of documentation. Tell us what your receiving team needs before production starts.
- Critical dimension inspection based on marked drawing features
- First article photos or key dimension records when required
- Material and finish notes carried through quotation and production
- Photos of completed parts before shipment
- Special packing notes for cosmetic, threaded, or fragile features
- Repeat-order notes for stable production of validated components
Certificates and Quality Documents
Certificates help overseas buyers understand factory compliance and quality management readiness. Larger document copies can be shared during RFQ review when needed.
Certificate 1
Quality and factory documentation available for buyer review.
Certificate 2
Quality and factory documentation available for buyer review.
How XHR Controls Risk Before Shipment
Quality control for custom machined parts starts before cutting metal. Drawing review, process planning, first article checks, in-process inspection, and final verification all reduce buyer risk.
Drawing Review
Before quoting or production, XHR reviews tolerance, material, threads, surface finish, critical dimensions, and manufacturability concerns that may affect cost or delivery.
First Article Check
For precision parts, the first piece can be checked before continuing batch production. This helps catch setup, tool, finish, or dimension issues early.
In-Process Inspection
Important features can be checked during machining rather than only at the end. This is useful for tight fits, repeated parts, and dimensions affected by tool wear or clamping.
Final Inspection and Packing
Before shipment, XHR can verify critical dimensions, surface finish, quantity, marking, packing, and buyer-specific requirements. Inspection reports can be prepared when requested.
Inspection Information Buyers Should Provide
- Critical dimensions on the drawing
- Required inspection method or report format
- Functional surfaces and mating faces
- Surface finish and cosmetic requirements
- Material certificate or treatment requirement
- Packing and export handling needs
Send these details through the RFQ page so XHR can review your part, confirm practical tolerances, and prepare a clearer quotation.

Best-fit parts
Inspection planning, first article checks, in-process measurement, final reports and export packaging confirmation.
Drawing details to include
Share 2D drawings, 3D files, material grade, quantity, tolerance notes, surface finish and inspection requirements.
Tolerance and inspection focus
Focus on critical-to-function dimensions, measurement method, inspection sampling, report format and photo confirmation.
Cost and lead-time drivers
Setup time, programming complexity, material availability, fixture needs, surface treatment and inspection depth usually drive price and delivery.
FAQ
Can you inspect critical dimensions before shipment?
Yes. Mark critical dimensions on the drawing and we will focus inspection on those features before packing.
Can you provide inspection photos or reports?
Yes. We can provide inspection photos, key dimension records, and other agreed quality documents when required.
How do you reduce quality risk for repeat orders?
We keep drawing requirements, material notes, finishing details, and inspection focus points aligned so repeat batches can be checked consistently.
Quality Control Workflow for CNC Machined Parts
Quality control starts before machining. XHR reviews drawings, critical features, material, process risk, inspection method, and packing requirements before production.
Drawing review
Check tolerance, datum, thread, material, finish, and manufacturability questions before quotation.
First article check
Confirm critical dimensions before continuing batch production when required.
In-process inspection
Monitor important features during machining to reduce batch risk.
Final inspection
Check dimensions, finish, deburring, packing, labeling, and shipment readiness.
Buyer Checklist and Inspection Focus
- Mark critical dimensions clearly on the RFQ drawing.
- Tell XHR whether you need inspection reports, material certificates, or photos before shipment.
- Confirm packing requirements for cosmetic or precision surfaces.
- Use drawing revision control to avoid mismatched production requirements.
Clear drawings and inspection notes help XHR quote accurately, plan machining steps, and protect critical features before shipment.
