This author analyzes recent significant changes in the normative-technical documents in reference to grinding materials, determination of their properties, quality control and designation.The article also presents information on new classification of grain composition, bonding materials, hardness and structure of abrasive tools. Application domains were specified for different grades and parameters of grinding materials, along with their correspondence to foreign analogues. Particular attention was paid to super-hard abrasive materials based on diamond and cubic boron nitride (CBN), identifiers of their parameters as well as rational application domains in manufacturing engineering. The author also considers flexible abrasive tools. There are examples of designation of materials for abrasive tools and their individual parameters.
