Increasing the Efficiency of Vibro-Abrasive Treatment of Transport Machine Parts by Combining Processing Media

The technological features of vibro-abrasive treatment, which is widely used in the technology of manufacturing transport machine parts, are considered. The purpose of the study is to substantiate the effectiveness of the vibro-abrasive treatment effect in combined media on increasing the intensity of the process. Methodological studies included the substantiation of the technological scheme of vibration treatment in a combined media and the development of an analytical model of the influence of the mass-dimensional composition of the media on the intensity of treatment. The features of increasing the efficiency of the vibro-abrasive treatment process by combining the type and granulometric characteristics of the processing media are considered, the prospects and advantages of this type of processing are noted. A hypothesis is proposed and experimentally confirmed about the possibility of increasing the intensity of the vibro-abrasive treatment process and expanding its technological capabilities in the processing of parts with small grooves and holes due to the use of media with a combined composition in the processing. A new scheme for the vibro-abrasive treatment of parts in a combined processing media is proposed, which allowed to expand the capabilities of the technology, ensure the stability of the quality indicators of the treated surfaces, and increase the processing productivity. It is established that vibration treatment in combined media allows for a single transition, without changing the technological modes and processing conditions, to reduce the surface roughness from the initial to the required one, and also significantly increases the intensity of the process.
