Grinding is the process by which irregularities are removed from the edges of glass that has been cut. We use straight grinding machines and double edging machines to grind straight sides. These are equipped with diamond and polishing wheels that level out the glass edge in different ways. Based on the type of wheel we use, we can obtain a polished or a rough edge. Bevelling is a type of inclined grinding which uses diamond wheels and resinoids mounted on a tilting unit.
