Order decision table
| Drawing change area | What to compare | Possible result |
|---|---|---|
| Revision number | Old drawing vs new drawing | Confirms which version controls production. |
| End dimension | Bearing seat, thread, keyway, shoulder | May change machining cost and lead time. |
| Nut style or tolerance | Flange, preload, accuracy, tolerance | May require requote or new review. |
| Commercial impact | Cost change, quantity, delivery date | Decides whether quotation remains valid. |
Confirmation checklist
- Drawing change summary, revision number, changed pages, and responsible confirmer.
- End dimension, nut style, tolerance, material, surface treatment, and inspection report changes.
- Cost change, lead time change, quantity, packing, and whether a requote is required.
- Final approved drawing, quotation number, PO status, and production release decision.
Send us the changed drawing before production
Send weimute the old drawing, new drawing, revision number, and change list after quotation. Our manufacturing and sales team will confirm whether the quotation still applies or whether a requote is needed.
FAQ
Does every drawing change require a requote? Not always, but changes to end dimensions, nut style, tolerance, or inspection scope often affect cost or lead time.
Can production continue while the drawing is changing? It is risky. Reconfirm the final revision before production release. See the pre-production confirmation checklist.
