The book discusses the main components of grinding technology: abrasive materials and tools, features of the contact interaction of the abrasive tool with the machined surface, kinematics and dynamics of the grinding process, straightening of grinding wheels, etc. Particular attention is paid to the use of cubic boron nitride (elbo-ra) wheels, including new AEROBOR wheels, issues of high-speed and depth grinding technology, processing of heat-resistant alloys, wear-resistant and elastomeric coatings. Recommendations on selection of optimal characteristics of grinding wheels and grinding modes are given.
