The analysis of finishing operations shows on the metal-working enterprises of different industries, that the delete of burr and rounding of sharp edges on stamped details makes from 10 to 70 percent of general labour intensiveness of their production; cleaning and improvement of quality of surface of founding makes from 6 to 10 percent of general labour intensiveness of their making on an engineer; providing of low values of sizes of roughness of surfaces of details with the purpose of decorative treatment or preparation under the different types of metal plating makes from 10 to 15 percent of general labour intensiveness of their making. Essence of oscillation treatment is a mechanical or chemi-mechanical process of output of shallow particles of metal from the processed surface, and also smoothing out of roughness by their flowage. The process of vibrating is accompanied by the successive causing on the processed surface of large number of small blows, which caused by an action directed vibrations which are given to the detail through a working instrument.
