What should customers prepare before a machining RFQ?

Service Review

This is not just order taking. The delivery boundary is reviewed first

Before quoting, buyers need to know what will be checked, what affects quote and lead time, and what confirmation they will receive.

Review the packet

Check geometry, material, tolerance, finish, quantity, and deadline before pricing.

Split the process path

Review machines, fixtures, tooling, outsourced finish, inspection, and packaging.

Return quote boundary

Separate price and lead-time drivers so the buyer can decide internally.

The 3 decisions buyers need

Can it be made? Geometry, material, tolerance, and process path are reviewed first.

Where can it get stuck? Fixtures, tooling, finish, inspection, and packaging are separated.

How is it quoted? Quantity, timeline, appearance, and document needs define the quote boundary.

Project Notes

Slow quotes often come from missing decision data rather than unwilling suppliers.

When material, critical dimensions, tolerances, finish, quantity, and target date arrive together, process review is faster and budget control improves.

Main quote and lead-time drivers

Critical tolerance

Tighter tolerance increases fixture, tooling, and inspection time.

Thin walls and deep pockets

Thin walls and long tool reach affect distortion and tool marks.

Finishing

Blasting, brushing, anodizing, and masking define cosmetic risk.

Quantity rhythm

One prototype and repeat small batch use different planning.

Fit

Best way to move forward

Housings, brackets, fixtures, heat sinks
Prototype moving toward small batch
Dimension record or cosmetic check required

Risk

Cases that should not go straight to quote

Photos only with no target dimensions
Material, tolerance, and quantity missing
Every dimension marked as tight tolerance

What we check during drawing review

3D and 2D consistency

Critical dimensions and datums

Material grade and heat treatment

Finish impact on assembly

Inspection method feasibility

Packaging and labeling needs

After Review

What the buyer should receive after review

A useful reply is not only a price. It should separate risk, lead-time logic, and delivery boundary so the buyer can move internally.

What To Send

Send these items together for faster review

Incomplete data can still start a discussion, but complete RFQ data makes pricing faster and clearer.
