Increase of efficiency of polishing of fir-tree interlocks of shoulder-blades of turbo-compressors

The questions of improvement of polishing of fir-tree interlocks of shoulder-blades of turbo-compressors are examined. The article contains the results of theoretical and experimental researches of efficiency of power of profile polishing of shoulder-blades of turbo-compressor of a diesel engine. It is shown that as a result of polishing of fir-tree interlock with the correction of circles by diamond rollers at opposite direction of circles and rollers, roughness of a treat surface and its corrugation will reduce, and the labour productivity and firmness of instrument increase as compared to passing direction of rotation of circles and rollers. Working results reflected in the article are adopted as technology of finish abrasive treatment and software on "Penzadizeimash" OJSC and "SKBT" OJSC (city of Penza), application of which make possible promotion of the indexes of quality of working surfaces of details.
