CNC Machining Quality Inspection and Drawing Review
Review critical dimensions, inspection methods, reports, material certificates, surface finish checks, and packaging-sensitive areas before production and shipment.

Quality support scope
Quality Inspection Support Scope
Quality inspection should be discussed before production, not only after parts are finished. KENDORIC helps overseas buyers review drawings, CAD files, critical dimensions, material notes, finishing requirements, inspection expectations, and report needs before quotation. The goal is to focus inspection on features that affect fit, function, appearance, assembly, and shipment acceptance.
Drawing and Tolerance Review
Drawing notes, datums, tolerances, threads, critical dimensions, and inspection expectations.
Critical Dimension Checks
Bores, shafts, hole positions, flatness, runout, sealing faces, bearing fits, and assembly-critical features.
Inspection Method Discussion
Calipers, micrometers, height gauges, thread gauges, bore gauges, CMM-style inspection, or focused reports.
Final Review and Packaging Notes
Surface condition, deburring, quantity, marking, visible surfaces, and packaging-sensitive areas before shipment.
Pre-production review
Drawing Review Before Production
Drawing Notes
Material, tolerance, surface finish, heat treatment, marking, and inspection notes.
Datum and Setup References
Datum surfaces, measurement orientation, multi-setup features, and assembly references.
Functional Features
Bores, shafts, sealing faces, locating holes, threaded holes, and mating surfaces.
Unclear Requirements
Questions about coating effects, cosmetic surfaces, report needs, or post-finish dimensions.
RFQ checklist
CNC Inspection Requirements Checklist for RFQ
| Inspection Item | Why It Matters | Buyer RFQ Notes |
|---|---|---|
| Critical dimensions | Confirms features that affect fit, function, or assembly | Mark critical dimensions on the drawing |
| Datum references | Defines how features are measured | Confirm datum surfaces and assembly orientation |
| Bore and shaft fits | Controls movement, alignment, or press/slip fit | Provide fit requirement and mating part information if available |
| Thread features | Affects assembly and fastening | Specify thread standard, depth, and gauge requirement if needed |
| Surface finish | Can affect sliding, sealing, appearance, or coating | Mark functional and cosmetic surfaces |
| Coated or treated dimensions | Finish may affect final size or surface condition | State whether dimensions apply before or after finishing |
| Inspection report | Helps buyers review key dimensions before shipment | List dimensions that need recorded results |
| Packaging-sensitive surfaces | Prevents damage during shipping | Identify visible, sealing, or precision surfaces |
Measurement planning
Measurement Methods and Reports
Basic Measuring Tools
Calipers, micrometers, height gauges, plug gauges, thread gauges, and bore gauges for common features.
CMM-style Inspection
Used when hole positions, datum relationships, profiles, or multi-feature relationships require closer review.
Focused Inspection Reports
Reports should focus on critical dimensions and agreed inspection points rather than every non-critical feature.
Pre-shipment review
Final Review Before Packaging and Shipment
Surface and Finish Condition
Deburring, scratches, coating condition, visible faces, marking, and cosmetic surfaces.
Quantity and Documentation
Quantity confirmation, photos if required, inspection reports, material certificates, or finish documents when agreed.
Packaging-sensitive Areas
Threads, precision edges, sealing faces, coated surfaces, and visible areas should be protected where necessary.
