る。When polishing the surface of a product using the above method, it is customary to place the product in a closed cabinet and project a projectile onto the product. However, depending on the product, it may be necessary to polish only a portion of the surface, and other portions may be better not to come into contact with the projectile material or dust. For example, when it comes to a product that has been heat treated after cutting, it is desirable to remove only the flakes and heat treatment scales from the cut parts by polishing.
