摘要： A glass grinding method starts with an assessment of the scratch or surface defect to be removed. A series of abrasive pads with different diameters and different grits from 60, 120, 180, 220, and 400 grit are selected according to the depth of the scratches or defects on the glass, and is installed on a handheld circular grinder. The work area is restricted to an imaginary area around the scratch that is two times the length of the scratch squared. The area is worked and feathered out with successively finer and finer dry abrasive pads applied flat on the surface of the glass. During this process, the glass surface temperatures are monitored and not allowed to exceed 150° F. Any glass powders that stick and build up on the abrasive disk faces are knocked off by slapping them with wire brushes or rasps. They are not brushed off. In a final pre-polishing stage, the powders are allowed to build to gradually reduce the cutting action and produce a finer surface. When the glass has only a haze left to remove, cerium oxide powders mixed in water are misted from a spray bottle onto a felt pad installed on the grinder. The area is outlined with a dry-grease marker applied on the backside of the glass.
