The article is devoted to application of ferromagnetic liquids in machining attachments of technical process for producing machine components. Application of such liquids allows to simplify equipment and decrease its cost, to increase accuracy of workpieces treatment by elimination of additional processing of workpieces base surfaces. It is proposed to set the workpiece not on supports of machine-tools but on the layer of rheological liquid hardened in outer magnetic field. At the same time contact pressure of rheological medium on side surface provides slip resistance caused by the forces appearing during treatment. The article contains calculated dependences for definition of forces holding the workpiece on machine table, being fully or partially submerged into ferromagnetic medium during mechanical processing. Criterion for applicability of ferromagnetic liquid at workpiece setting during treatment is proposed. On the ground of achieved per samples experimental verification of formulated statements and calculated dependences the authors worked out recommendations for selection of rheological media in liquid state for workpiece setting and holding taking into account frequent changes of working objects. Development and running of such machining attachments is efficient in modern industry that is characterized by low serial production and wide assortment of produced goods during finishing mechanical, electrical and combined work, where scientifically grounded application of ferromagnetic liquids increases production profitability by 1, 5-2 times.
