Cold-plastic forming technologies are one of the most dynamically developing technological processes in these days The main purpose of modern plastic forming is to achieve the shape and size of the designed component by providing minimum environmental loads, while ensuring the proper values of strength and deformation characteristics.These methods include surface strengthening processes, characterized by the introduction of cold forming hardening and residual compressive stress [1]. In this paper, we study the main types of surface consolidation in detail to burnishingof outer cylindrical surfaces.The application of burnishing results in cost reduction in several aspects: cheaper, lower alloyed, lower rigid structural materials can be used as raw materials, abandoned grinding and other fine surface machining, can be replaced by heat treatment operations. In our investigation we used polycrystalline diamond tool with spherical machining surface on C60 hardened steel examining the changing of surface micro-hardness caused by different burnishing parameters.References
