Grinding (abrasive cutting) - Wikipedia
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.).

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.
