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.

Cross-sectioning

Grinding is done after the specimen has been cut to its optimum size. A typical grinder/polisher has a platen (or a set of platens) over which the grinding material (SiC paper, polishing cloth, diamond paste, etc.) is placed. Grinding is often started using a 120 or 240 Grit SiC paper. The grinding process then progresses through 320, 400, and 600 Grit SiC paper.
