Upgrading of treatment of car parts at the expense of is due to the decline of coefficient of friction and clinging effect

Finishing-grinding surface treatment of parts, the purpose of which is to clean parts, debus, rounding sharp edges, preparation of surfaces for coating their grinding and polishing, is used in all industries, especially in mechanical engineering and instrument making. Analysis of the production of machine parts of various branches of engineering have shown that various types of finishing processing is subjected to 85-95% of parts produced, the complexity of these op-erations is 10-20% of the overall complexity of manufacturing. Today, one of the ways engineering is a manufacturer of machine parts high quality, durability and reliability which largely depend on the accuracy of their production, the optimal physical and mechanical properties of surface layers of the mating surfaces. This, in turn, requires improved methods of finishing, especially in the finishing operations, expansion of production capabilities, introducing them to new technological processes. Among the productive methods of performing finishing (and grinding) operations, there is a vibration processing method, which is characterized by providing high quality machined surfaces and wide versatility of the vibration machine. However, when vibration processing small flat parts, there is uneven treatment of their surfaces from sticking together in the package and buildup on the walls of the vibrating container. All this requires exploration of new technological opportunities of the vibration treatment, characterized by higher intensity and performance, high quality, new methods, contributing to the elimination of build-up detail on the sides of the container and sticking them together in the process. In this regard, we have focused on actual scientific and technical problem of developing and implementing an effective process vibro- abrasive processing small flat parts on the basis of evidence-based selection methods, empowering vibration processing by changing the shape of the container and functions of the working environment, which provides the processing and separation of the sticky details. The paper shows experimental evidence that increasing the kinematic viscosity of the working environment, the thickness of the film on the treated surface is increased, which reduces roughness and reducing the shear strength of flat samples relative to each other
