Factory Acceptance Checks for an Endless Sanding Belt Slitter

Before signing off a factory acceptance test for an endless sanding belt slitter, decide how you will prove that the machine holds the minimum slit width of 6 mm and handles the full supported belt length range of 530–4,000 mm. Ask the supplier to run belts at both ends of that range and at the maximum input belt width of 650 mm, then record the measured slit width on each sample.

Build the test around questions a buyer can answer with evidence: Does every slit measure at or above 6 mm, and how is that measured? Are belt edges clean and square on abrasive material? Does the machine feed belts of different lengths without jamming? What sample count and tolerance define pass or fail?

Treat catalog values such as 650 mm, 6 mm, and 530–4,000 mm as reference figures, not guarantees for the supplied unit. Agree the test material, measurement method, and acceptance record in the request for quotation.

Before requesting a quote, confirm with the supplier which belt widths and lengths the offered configuration actually supports, how slit width is verified, and what documentation and rework terms accompany a failed acceptance test.
