Metallographic grinding and polishing insight Struers During polishing, a smaller chip size is desirable to ultimately achieve a specimen surface without scratches and deformation. More resilient cloths are used, along with smaller grain sizes, such as 3.0 or 1.0 µm, to obtain a chip size approaching zero. A lower force on the specimens will also reduce the chip size during polishing.
