Metallographic grinding and polishing insight | .Traduire cette page

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. Grinding removes material using fixed abrasive particles that produce chips of the specimen ...

Metallographic Polishing and Grinding - Kemet

Excessive pressure during rough grinding will form deep scratches, and will increase the depth of disturbed metal on the surface of the specimen. This disturbed layer may extend from ten to fifty times the depth of the scratch produced by an abrasive grain. The initially deformed layer is reduced in depth by the application of a finer abrasive. However, the finer abrasive also produces another ...
