Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
Surface Grinder. A surface grinder is a type of grinder. The workpiece is mainly rotated by a grinding wheel to achieve the desired flatness.
