The work purpose: the accuracy investigation of parts machined with chromium diiodine grinding disks, and also roughness and structural state of surface layer material in parts after working with the impregnated tool; the investigation data are a part of the scientific work which has been started since 2012.
The investigation methods: the accuracy and quality of machining parts with the impregnated grinding tool were analyzed; there was carried out a generalization of the data obtained regarding quality parameter changes in the surface layer of parts during working having an influence upon their operation characteristics.
The investigation results and novelty: the impregnation method including additional mechanical oscillation at the moment of tool impregnation; the investigation results of accuracy and effectiveness of the mentioned method of working; the investigations of roughness parameters and distribution of residual stresses in the surface layer of parts.
Conclusions: at present in the Russian industry there are widely used methods and technologies of import substitution, industry needs low cost and efficient methods of working; thereupon there are urgent different investigations in the field of updating technology for metal grinding with the estimate of their effectiveness and qualitative characteristics of parts when using tools offered.
