- The paper presents selected results of experimental research of burnishing process of the steel tube holes. The ballizing process (NPS) is the method of burnishing where consists of pushing the tool through the hole, wherein the ball is greater in size than the opening of the value of the reduction ratio. Used tools to burnishing are hard and smooth surface. Burnishing elements are made of shape: ball, roll and disk. The ballizing process is carry out by a ball. The precise tube holes are made mostly methods abrasive machining. Machining these methods can usually maintain a within the tolerances established by the constructor size and shape and surface roughness. However, not achieved a satisfactory state surface layer of tube holes. Improve the properties of the surface layer can be obtained after application, as finishing, the slide burnishing. Modelling of the burnishing process using the method, NPS is to determine the impact of a specific curvature a rigid tool with of the workpiece. Ballizing process can increase the dimensional accuracy of tube holes, reducing the surface roughness, the strengthening of the surface layer, compressive residual stresses constitution. Compressive internal stresses substantially influence the fatigue life of machine parts. The aim of experimental research was to obtain surface layer state of compressive residual stress and the material ratio curve of convexity shape.
