During metallographic grinding, metal is pushed into the pores. If the next polishing steps are not carried out properly, residual metal 'lids' will be left over the pores (particularly in soft materials). If not removed, these lids will obstruct evaluation. Therefore, fine grinding should be followed by a thorough diamond polish.

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).
Nowadays, grinding is mainly used for the following purposes: (i) To remove a very small amount of metal from the workpiece to bring its dimensions within very close tolerances after all the rough finishing and heat treatment operations have been carried out.

Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
