Testing a Sanding Disc Die-Cutter on Your Own Abrasive Stock
Buyers should require a demonstration on their own sandpaper or abrasive cloth, then verify disc quality, cut consistency, and throughput against the reference specifications before acceptance.
Make the demonstration run on your own sandpaper or abrasive cloth, not on the supplier's sample stock. Abrasive materials vary in backing, grit, and coating, so a clean cut on one roll says little about another. Ask the supplier to cut your material at the reference working width of 1,400 mm and with the reference press force of 40 t, then inspect disc edges for fraying, delamination, or incomplete separation.
For the trial, define the disc sizes you actually buy, noting that the reference disc diameter is less than 400 mm. Confirm the punch-head stroke range of 5–150 mm suits your tooling and ask how stroke, force, and feed rate are set and recorded. Compare cut quality and output across several cycles, and agree on measurable acceptance criteria such as edge condition, dimensional repeatability, and scrap rate.
Before requesting a quote, confirm with the supplier which reference values are standard versus configurable, whether a demonstration on your material is offered, how test results are documented, and what tooling and material the trial requires.
