[0002] Cylindrical grinders are used to grind the outer surfaces of cylindrical, conical, or other shaped workpieces, as well as the shoulder end faces. They are primarily used for precision grinding cylindrical parts (workpieces) to achieve precise dimensions and surface quality. These grinders are commonly used to manufacture shafts, bearings, pins, cams, and other similar parts. During the grinding process, large amounts of dust are generated, filling the workroom. This high amount of dust poses a threat to the environment and the health of workers, requiring dust removal mechanisms to handle the dust.
