The polishing wheel of the automatic polishing machine differs according to the distance of the suture, and the polishing wheel has soft and hard points. The smaller the distance of the suture, the harder the polishing wheel. In addition, sewing the fabric of the polishing wheel will directly affect the hardness of the polishing wheel. In order to make the polishing wheel softer, the polishing wheel should be made with a sufficient distance between the sewing thread and the wheel edge (also not stitched). Polishing large workpieces also uses a polishing wheel with a special air-cooling device.
