Urgency of the research. To ensure the high competitiveness of modern domestic enterprises, it is necessary to increase the productivity of the processing process, provided that the required quality and accuracy is ensured. Target setting. In order to achieve high technical and economic indicators in finishing machining of parts, it is necessary to improve existing ones or develop new effective methods of grinding. Actual scientific researches and issues analysis. There are methods of deep grinding with crossed axes of the tool and a cylindrical part and a method of longitudinal circular multi-pass grinding of a part with the periphery of a cylindrical circle a exist. Uninvestigated parts of general matters defining. The experimental research of the finishing single pass grinding of the cylindrical surface of the shaft with an oriented tool are absent. The research objective. To ensure high quality requirements, geometrical dimensions and accuracy of cylindrical parts, it is necessary to improve existing ones or develop new effective methods for finishing. The statement of basic materials. To ensure the processing of cylindrical shafts in a single pass with a uniform distribution of the allowance along the periphery of the grinding wheel, a method of finishing single pass grinding of the cylindrical surface of the shaft with an oriented tool is used. Conclusions. Experimentally determined active power during finishing single pass grinding, depending on the size of the allowance and the longitudinal feed. The temperature distribution during processing was determined. The roughness of the processed surface of the part is Ra = 0,63 – 1,25 μm.
