Diamond mechanical polishing
WebPolishing is divided into two different processes: Diamond polishing Diamonds are used as an abrasive to accomplish the fastest material removal and the best possible planeness. No other available abrasive … WebDiamond Polish. Polish refers to the degree of smoothness of each facet of a diamond as measured by a gemologist. When a diamond is cut and polished, microscopic surface defects may be created by the polishing wheel as it drags tiny dislodged crystals across the diamond's surface. Depending on the severity, these defects may disrupt light ...
