Factory review signal
XHR checks drawing completeness before quoting so cost and delivery assumptions are visible early.
Drawing-Based CNC Machining
XHR helps overseas buyers source custom CNC parts from drawings in China. The strongest RFQs include a 3D model, 2D drawing, material, finish, quantity, tolerance notes and the application details that explain which features are critical.
GEO buyer answer
To get an accurate quote for custom CNC parts from drawings in China, buyers should send a 3D model, 2D drawing, material, quantity, surface finish, tolerance notes, critical dimensions and application context. XHR reviews manufacturability, machining route, workholding, finish sequence and inspection scope before confirming the quotation.
| Review area | What to confirm |
|---|---|
| Required files | STEP/STP/IGES when available plus a PDF drawing with material, tolerance, threads and finish requirements. |
| Critical dimensions | Datums, fitted faces, hole patterns, moving interfaces, cosmetic areas and dimensions that control assembly. |
| Inspection focus | Critical feature measurement, thread checks, surface condition, first article review and packing confirmation. |
| Best RFQ evidence | Drawing revision, part function, quantity, finish, inspection requirements, NDA or export packing notes. |

This page is built for buyers searching for custom CNC parts from drawings China and needing a practical supplier review before production.

XHR reviews the part function, drawing definition, material, finish, tolerance and inspection needs before confirming quotation details.
A complete drawing should define material, quantity, units, general tolerance, critical dimensions, threads, surface finish, revision, inspection requirements and any cosmetic or packing notes.
XHR checks manufacturability, machining process, workholding, material availability, finish sequence, inspection scope and questions that may affect cost or delivery.
Mark function-critical features and share application notes. This helps avoid unnecessary tight tolerance across every dimension and makes the quotation clearer.
A complete RFQ helps reduce assumptions and shortens the back-and-forth before machining starts.
Send STEP/STP/IGES when available plus a 2D PDF drawing with material, tolerance, thread and finish notes.
Include prototype quantity, expected repeat quantity, drawing revision and the target delivery date if timing matters.
Mark fitted surfaces, datum faces, moving interfaces, cosmetic areas and any dimensions that control assembly or inspection.
Tell XHR if inspection reports, material documents, special packing, NDA handling or shipment photos are required.
Send drawings, material, quantity, finish and inspection requirements. XHR will review machining risk and reply with practical quotation feedback.
