Grinding and Polishing GRINDING removes saw marks and levels and cleans the specimen surface. Polishing removes the artifacts of grinding but very little stock. Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on

They are used to grind down the concrete surface to achieve the desired degree of smoothness and shiny texture in the concrete. Like the process of sanding wood, when the grinder moves on the concrete surface, it produces fine particles of concrete dust due to grinding. After removing the concrete dust, a fine mirror-like glossy finish is obtained.

Surface grinding technique: roughing corner/finishing corner Case in point: I cut a 50 x 400mm strip of 1.2842 (90MnCrV8 or AISI O2 tool steel) from a 10 x 150 x 400mm plate. The plate was ground parallel both sides (Blanchard) but after I cut out the strip, the strip was bowed about 0.3mm (0.012") from internal stress.
