Grinding and Polishing - Materials Engineering - Purdue ...

Mechanical grinding and polishing consists of removing material from a specimen with increasingly fine grit grinding paper or polishing compounds (typically performed on a rotating wheel platen). Common practice is to hold a specimen at one orientation per grinding/polishing step to keep scratches in a uniform direction.

Metallographic Abrasive Grinding

Thus, for larger hard specimens higher grinding/polishing pressures increase stock removal rates, however higher pressure also increases the amount of surface and subsurface damage. Note for SiC grinding papers, as the abrasive grains dull and cut rates decrease, increasing grinding pressures can extend the life of the SiC paper.
