Abstract: The tensile strength of straight profile grinding wheels, in which cement was used as a binder, was investigated. It has been established that the breaking speed of such circles is 42 m / s, which allows them to be safely operated at operating speeds up to 20 m / s. It is shown that the formulation of a wheel with cement as a binder and the percentage of grains, binder and fillers, similar to the formulation of circles on a bakelite bond, is not optimal, both from the point of view of the strength of retention of grains on the working surface of the tool, and from the point of breaking the strength of the circles. The results obtained indicate that further experiments are required to select a rational formulation of cement-bonded wheels and its approximation in the percentage of components to concrete grades M400 - M600.
