The surface of the finishing machined parts is defined mainly by roughness parameters. Growing demands on the part, especially mating sliding or rolling, require the specification of additional parameters, such as waviness parameters, particularly when there is significant resistance to seizing or noise reduction. This paper presents surface waviness characteristics of hardened burnished steel.

The objective of this research aims to improve surface roughness of the hardened 145Cr6 (DIN) steel using the hydrostatic burnishing tool. The ball burnishing process with hydrostatic tools is very economical finishing process for various types of machine parts. This process reduces the height of surface unevenness, introduces compressive stresses at high depth (approx. 1 mm) and increase the hardness of the surface layer. The flat surface optimal ball burnishing parameters have been determined after conducting the Taguchi L9 matrix experiment. The input parameters are speed, burnishing force and burnishing width. It also showed a positive effect of hydrostatics burnishing on roughness and geometric structure of the surface. In most cases, the result is anisotropic surface, reduced roughness, reduced amplitude values of parameters such as: Sa, Sz.

Burnishing Process

Burnishing is an effective chipless finishing process for improving workpiece properties: hardness, vibration resistance and surface quality. The application of this technology is limited to rotationally symmetrical structures of deformable metals. Because of the multiaxial characteristics, the transfer of this force controlled technology on to prismatic shapes requires a comprehensive process development. The main purpose of this paper is the characterization of a plain burnishing process on aluminium EN AW 2007 with a linear moved, spherical diamond tool. The method of design of experiments was used to investigate the influence of different machined surfaces in conjunction with process parameters: burnishing force, burnishing direction, path distance and burnishing speed. FEM simulation was utilized for strain and stress analysis. The experiments show, that unlike the process parameters the initial surface roughness as 3rd order shape deviation does not have a significant influence on the finished surface. Furthermore a completely new surface is created by the process, with properties independent from the initial surface roughness.

The current study discusses the surface finish of several common die materials, of which the screw-surface is finished by compound processes of electrochemical finishing and burnishing. The burnishing-tool uses ceramic material connected with the electrode and moves, following the electrode, to burnish the workpiece. In the experiment, the electrode is used with a continuous and pulsed direct current. The results show that the use of a higher rotational speed for the electrode and burnishing-tool is advantageous to the finish. A partial form with a thinner heavy section performs the best finish effect in the current investigation. Pulsed direct current can slightly improve the finish effect. The burnishing process can increase the finish effect. An effective and low-cost finish processes through burnishing assistance following electrochemical finishing after screw machining offers a fast improvement for the surface roughness of the screw-surface and is a new application in the screw finishing process.

On the foundation of the methods and mechanisms of electrochemical finishing with high-frequency group pulse we studied before, properties of the finishing process with ultrahigh-frequency group pulse were studied, effects of pulse effect on the finishing result were also researched. With the Ultrahigh-frequency group pulse power we designed, we designed a equipment with high precision and easy operation. After some single-factor experiments, we obtained the laws of how the main pulse influenced the result, from the Ra of 2Cr13 stainless steel surface.

The heating, generated in the process of deformational cutting without chip separation used for phase transformation in steel during lathe machining. Chips are not separated from the workpiece and remain on the surface thus forming a special reinforced structure. The result of processing is a steel surface quenching up to 1 mm deep. The proposed method also makes it possible to obtain hardened surface structures with alternating inclined layers of different hardness. The article presents calculations of heating and cooling rates, types of hardened structures, hardness investigation of hardened steel surfaces.
