Quick answer
An end machining drawing must show every diameter, length, thread, shoulder, groove, keyway, and tolerance needed to manufacture the shaft ends. For weimute, the best RFQ file is a drawing plus a short checklist that confirms support units, nut orientation, quantity, inspection, and export packing.
Buyer decision table
| Drawing area | Must show | Why it matters | | --- | --- | --- | | Fixed end | Bearing seat, thread, lock nut, shoulder | Controls preload and fixed-side assembly. | | Supported end | Support diameter, length, chamfer | Controls fit with BF or other support unit. | | Thread section | Thread length, usable stroke, nut position | Prevents stroke and mounting mistakes. | | Special features | Keyway, groove, hole, surface treatment | Adds machining process and inspection needs. |
End machining drawing checklist
- Fixed side: show bearing journal diameter and length, shoulder, lock thread, and retaining groove if used.
- Support side: show support side diameter, length, chamfer, and any keyway.
- Drawing control: include drawing revision, units, tolerance, and material or surface notes.
RFQ checklist
- Attach PDF drawing and editable CAD file if available.
- Confirm all dimensions are in millimeters and all tolerances are visible.
- State support unit model, nut type, accuracy grade, preload or backlash requirement.
- Add quantity, delivery target, destination country, and packing requirement.
- Request inspection photos or reports if your internal approval needs them.
Send us your end machining drawing
Send weimute the end machining drawing with the checklist above. Our manufacturing and sales team will identify missing dimensions, manufacturing risks, and inspection points before final quotation.
FAQ
**Can a quotation start from a partial drawing?** Yes, but production cannot start until missing end dimensions are confirmed.
**Which format is best?** PDF is good for review, and an editable CAD file helps reduce interpretation errors.
