Edge polishing is a finishing process that smooths out the edges of glass. The sharp edges left after cutting are dangerous and look rough, so polishing creates a safe and beautiful finish. Felt pads and polishing bits are used to achieve the final shine.
For edge grinding, use fine-grit pads with grit numbers ranging from 400 to 1000 in sequence, and finally apply a polishing agent such as cerium oxide to achieve a finish close to a mirror finish. The Silky Diamond File (SDF50) is ideal for the final finishing step in manual polishing. Maintaining a consistent polishing direction and applying even strokes to the same area are the keys to achieving a uniform finish.
