Technical guides
A buyer-side checklist for CAD files, quantities, materials, finishes, and inspection requirements.
Engineering overview
A clear CNC machining RFQ gives the supplier a consistent basis to review the part, quantity, and acceptance requirements. Use this checklist to separate confirmed requirements from open questions. Specific process, material, inspection, and schedule details still need project review.
Representative visualProcess comparison
These inputs reduce avoidable clarification and help the quotation state its assumptions. Use the current controlled revision for every file.
| RFQ item | What to provide | What it helps clarify |
|---|---|---|
| Part geometry | A 3D model, preferably a neutral CAD format such as STEP or STP. | The complete shape, feature access, and overall part envelope. |
| Drawing | A dimensioned PDF with units, datums, tolerances, threads, notes, and revision. | Requirements that cannot be reliably inferred from the model. |
| Commercial scope | Part number, quantity, alternative quantity tiers, and delivery destination. | The exact pricing basis and planning context. |
| Material and finish | Exact grade and condition when fixed, plus finish specification and masking notes. | Material sourcing, process compatibility, and post-finish dimensions. |
| Acceptance | Critical characteristics, inspection priorities, and requested records. | How the finished part will be evaluated and documented. |
A 3D model communicates shape; a dimensioned drawing defines tolerances, datums, threads, notes, and revision requirements that may not be clear from the model alone.
The requested quantity and material specification frame both technical and commercial review. If you are comparing batch sizes, include each quantity in the same inquiry and keep the specification consistent.
Technical guides / Manufacturing context
Representative media supports the engineering discussion and does not document a specific customer order.
The application context helps reviewers understand which surfaces and dimensions determine fit, motion, sealing, assembly, or appearance.
A requested date and destination are useful for planning, but production and shipping timing must be reviewed against the project scope and confirmed separately from the quotation response.
Before you request a quote
Use these answers to prepare the requirements for your part. Project details are confirmed during drawing review.
A model defines geometry, but it may not communicate tolerances, datums, threads, surface requirements, inspection needs, or revision control. Include a dimensioned drawing when those requirements affect acceptance.
Yes. List each quantity by part number and keep the material, finish, drawing revision, and inspection scope consistent so the price comparison has a common basis.
Identify which requirements are fixed and which remain open. A quotation can then state assumptions instead of treating an unresolved design point as an approved manufacturing requirement.
Request them during quotation. The required dimensions, sampling approach, record format, and availability should be agreed before the order is released, not after parts have been completed.
Ready for engineering review
Send your drawings and let our engineering team review your project.
We will provide your quotation within 24 hours after we receive complete drawings and project requirements.
Make the requirements clear
Include quantity, material, finish, critical dimensions, and any inspection requirements.
