surface roughness vs abrasive mesh size. GRINDING WHEEL and ABRASIVES BASICS. Grit size. Grit size typically runs from coarse (16 24 grit), medium (36 60 grit) and fine (80120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing …

Surface Texture: Lay. Lay refers to the predominant or primary direction of the surface texture pattern on a material or object. It is a fundamental aspect of surface texture analysis, often assessed alongside roughness and waviness. The lay can be described as the orientation of the surface features or texture, and it plays a crucial role in ...
