摘要：The article presents comparative experiments by the examination of conditions of the increase of the accuracy of geometric forms of surfaces ground by the grinding wheel with various grain sizes of a new construction and a standard grinding wheel. In comparison with the standard grinding wheel, it is given that the accuracy of the geometric form basically increases by grinding with the wheel of various grain sizes. It is explained by the fact that the concentration on the working surface of the grinding wheel of various grain sizes with four grain sizes, from the coarse one to the finest one, enables the connection of elements of the coarse and fine grinding in one technological transition. The acquired empirical dependencies allow us to set the high efficiency of the grinding wheel of various grain sizes and to determine the rational sum of elements of the grinding mode in order to find out the basic conditions of their application.
