Abstract

The article deals with the method of combined grinding of materials, providing simultaneously preliminary and final surfaces treatment on one machine tool. The analysis of existing grinding methods showed that depending on volume of details exhaustion, a preliminary and final grinding can be executed at one or two technological operations. In the first case, the preliminary and final grinding is carried out on the same workplace with the replacement of coarse-grained with a fine-grained grinding wheel. In the second case, after the preliminary operation, the workpiece is transported to another workplace for final processing. In both variants, a large amount of auxiliary time is required, which leads to a decrease in the productivity of the technological operation. The noted deficiencies are eliminated by using the method of combined grinding. Possible combined peripheral grinding schemes were developed and analyzed, elastic displacements of the spindle knot with a tool under the action of cutting force were determined, on the basis of which a scheme was chosen, that ensures rational arrangement of coarse-grained and fine-grained wheels on the machine spindle. The technological possibilities of the combined grinding were determined, The comparative experimental data of the microgeometry of surfaces, processed by proposed and traditional methods, are given. Combined grinding allows reducing the machine and auxiliary time for the performance of technological operation and to increase the processing productivity with the same microgeometry of the surface, typical for traditional grinding.
