The fiber disc is a unique abrasive medium. Compared with ordinary sandpaper, the fiber disc has a longer service life, higher grinding efficiency, and is able to better maintain the accuracy and surface quality of the workpiece. This kind of sand disc is composed of a thin steel plate bottom layer, a non-woven fabric middle layer and a sandpaper surface layer, which can be used with high-speed rotating tools, and can complete various workpiece grinding, polishing, cleaning and other operations in a short time.
