する特徴のある砥石を形成している。"Prior Art" Conventionally, a grinding wheel is made by solidifying and molding abrasive material as abrasive grains into a desired shape and size using a binder having an appropriate degree of bonding and structure. Commonly used binders include inorganic compounds such as vitrified (symbol V), silicate (symbol S), oxychloride (symbol ○), resinoid (symbol B), rubber (symbol R), and polyvinyl alcohol (symbol They are broadly divided into organic bonds, which are classified as PVA (symbol PVA), and metallic bonds, which are classified as metal (symbol M) and electroformed bonds (symbol P), each of which has its own unique degree of bonding and structure. It forms a whetstone.
