The article describes a way to increase the efficiency of an abrasive tool by its impregnation in an aqueous solution of chromium diiodide. The device scheme for impregnating the instrument is proposed. Research results of durability of tools impregnated with chromium diiodide and structural condition of material of a surface layer of details after processing are resulted. Within of the researches presented in the article the grinding processing a shafts made from various iron-carbon steels with prepared abrasive tools was conducted. As a result of the machining the scattering fields of the batch sizes of the parts within the grinding wheel resistance were determined. This data for processing with standard grinding wheels and impregnated by chromium diiodide were done. Using data from controlled grinding of workpieces, approximate values of the KΔ coefficient were determined depending on the diameter of the workpiece surface, the required size accuracy of part and the method application of the surfactants. It is shown that regardless of the material being processed, the use of a grinding wheel impregnated with chromium diiodide leads to a reduction in the specific value of the accumulated deformation energy Espec. Taking into account these results it is possible to predict up to twofold reduction of the cost of machining with the abrasive tool of grinding parts, which will reduce the cost of their manufacture by 20-25%. The developed process of impregnating grinding wheels with chromium diiodide can be used without large economic costs in many machine-building company also during repair works.

The paper considers the possibilities of using modern information technologies to solve the problems of ensuring the quality, accuracy of tooling, reducing the time and labor intensity of manufacturing, improving its design processes through the use of an electronic model of a part and a technological electronic model of tooling in technological processes of shaping parts on equipment with numerical control.
