  • Publication number: 20090094903
    Abstract: A profiling tool using an ultra-hard sintered body and an elastic material, and a method of producing the tool is provided. The profiling tool, used for grinding brittle workpieces, is produced by embedding ultra-hard sintered bodies in an elastic material such that the sintered bodies form a specific pattern, thus improving the grinding performance and lengthening the life span of the tool. The profiling tool includes a rotary metal body and a grinding part provided on the outer surface of the metal body. The grinding part is produced by embedding the ultra-hard sintered bodies in the elastic material such that the sintered bodies form a predetermined unit pattern and maintain a predetermined angle relative to the rotating direction of the tool. The metal body has both a shaft hole and a plurality of water outlet holes passing through the metal body outwards in radial directions from the shaft hole.
