Before approving a polishing wheel sample, compare its identity, dimensions, mounting, appearance and packaging with the agreed specification. Have a qualified operator check suitability for the equipment, then evaluate the sample against the required finish. Record the results and resolve differences before placing the bulk order.
Sample review steps
- Identify the sample. Record supplier, product reference, receipt date and the specification being evaluated.
- Check dimensions. Record diameter, thickness and bore or shank against the agreed values and tolerances.
- Inspect appearance. Check condition, contamination, visible damage and consistency with the requested construction.
- Review equipment requirements. Confirm the product’s operating instructions, mounting and speed limits for the intended machine.
- Evaluate the application. Record the workpiece, preparation, compound where applicable and test conditions; compare with your acceptance criteria.
- Review packing. Check the pack quantity, labels, protection and any agreed private-label requirements.
- Document the decision. Approve, request clarification or request a revised sample; record the reason.
What should the inspection record contain?
| Record | Details to keep |
|---|---|
| Product identity | Sample reference, supplier, date and agreed specification. |
| Measurement | Required value, measured value, units, tolerance and measurement method. |
| Application | Workpiece, preparation, equipment, approved conditions and target finish. |
| Result | Photos taken under comparable conditions, observations and any measured result. |
| Disposition | Reviewer, date, decision and outstanding questions. |
Do sample photos prove production consistency?
Photos help record appearance, but they do not replace measurements, agreed acceptance criteria or production checks. Keep the sample reference and the approved specification together so the next order can be compared with the same requirements.
What if a sample differs from the quotation?
Describe the difference, include measurements or photos and ask for clarification. Do not silently approve a different dimension, construction or packing method. Record any agreed change before proceeding.
Prepare for the repeat order
Keep the approved specification, product reference, packaging artwork and order details. Identify changes explicitly on the next purchase order. The checklist is a purchasing record; operating instructions and any applicable inspection requirements remain specific to the product and equipment.
