China OEM CNC machining describes a buyer-supplier arrangement: the buyer provides the part definition and the supplier quotes machining to that requirement. The phrase does not by itself establish a factory location, certification, machine list, tolerance capability or lead time. Confirm those details for the specific project.
Cosa inviare con una RFQ
Share the latest 2D drawing and 3D model where available. State the drawing revision, material grade, order quantity, expected repeat orders, surface finish, critical dimensions, threads, and any required certificates or inspection records. Mark which requirements are essential for acceptance.
Questions to resolve before comparing quotes
- Does the price cover material, machining, finishing, inspection, packaging and shipping?
- Are any operations subcontracted, and who coordinates them?
- Which dimensions will be checked, with what report, and against which drawing revision?
- What assumptions or exclusions could change the quoted price?
- When will the supplier confirm the production schedule and shipping terms?
Keep design and supplier responsibilities clear
The buyer should release controlled files and approve design changes. The supplier should quote against the specified revision and identify questions or manufacturing concerns before work begins. Record changes in writing so the quote, inspection and delivered parts refer to the same requirements.

How to compare suppliers fairly
Compare like-for-like quotes: identical files and revision, material, quantity, inspection scope, finish, packaging and delivery terms. Ask for evidence of any capability or certification that your project requires; do not infer it from a general service description.
Prepare a clear next step
Send the drawing package, quantity and target date, then ask the supplier to confirm scope, assumptions and open questions. This makes it easier to identify gaps before a purchase order is issued.
