regrinding

Second pass abrasion

Regrinding is grinding something again, typically to restore a worn surface or achieve a finer finish.

Machine tools, engine parts, and cutting implements undergo regrinding to extend their useful life: The valve seats needed regrinding after 100,000 miles.

In manufacturing, regrinding may refer to processing scrap material for reuse: plastic regrinding.
