Abstract:  
A tool for finishing the internal surfaces of revolution in blanks including a casing having a groove on its side surface for accommodating bodies of revolution which are moved by a fluid pressure. A fluid is fed in through channels in the tool casing, the channels putting the groove in communication with the source of fluid under pressure. The groove is surrounded by a cage accommodaing working elements which are installed with a provision for contacting the bodies of revolution and colliding with them in the operating tool. During this collision the working elements produce plastic deformation of the machined surface with a force which is somewhat smaller than in the known tools used for the same purpose.
