Abstract Nowadays diamond burnishing, which belongs to the cold plastic manufacturing procedures, is used more frequently for final finishing operations of parts. By its application, the surface roughness and the micro-hardness in the sub-layers of the components can be increased. The procedure of diamond burnishing can be performed for final finishing manufacturing of outer and inner cylindrical surfaces, and shaped surfaces (e.g. conical, spherical and even statue like) too. The parameters which effect to the surface features during manufacturing are burnishing speed, feed rate, burnishing force, the number of passes, material and geometrical data of the working part of the burnishing tool, furthermore the lubricant applied to burnishing. During our experiments we have chosen from the above mentioned parameters the burnishing speed, the feed rate and the burnishing force and we examined what is the effect of these parameters to the surface topography when manufacturing outer surface of cylindrical components by burnishing tool having given geometrical dimensions. The experiments were executed by the Factorial Experiment Design method. On the base of the evaluated experiment data the improvement ratio of surface roughness was determined by empirical formulas. The technological parameter and burnishing force values were shown out, which provided the highest improvement ratio of surface roughness.
