Abrasive belts are flexible strips made from materials like sandpaper or aluminum oxide that are used in various machines for grinding, sanding, and polishing surfaces. They come in different grits, which determine how coarse or fine the surface finish will be. These belts are commonly used in woodworking, metalworking, and manufacturing processes. The belts are designed to fit around a pair of pulleys in machines such as belt sanders or grinders. As the machine operates, the abrasive surface of the belt removes material from the workpiece, allowing for efficient shaping and finishing. Proper selection of the belt type and grit is essential for achieving the desired results.
