Today’s machines have to be characterized by increasingly better functional and operational properties. The devices should work faster, more efficiently with higher accelerations and at the same time use less energy than it was a few years ago. These requirements apply to the products from the automotive industry, aviation machine tools or machines serving people in everyday life to play or learn. At the same time, a guarantee of long and trouble-free operation is required. In connection with the above, it is increasingly difficult for the technologist to prepare parts that meet the very strict requirements of dimensional and shape accuracy and the state of the geometric structure of the surface (SGP). Also, more and more emphasis is placed on meeting the additional functional requirements of the part surface (hydrophobic or hydrophilic properties, the degree of isotropy or the ability to maintain coatings and lubricants). The paper presents the results of the work aimed at determining the effect of technological parameters of milling and burnishing when treating the surface of parts in the state improved by heat to high hardness. The work focused in particular on the determination of the impact of the strategy of the implemented treatment on changes in the value of SGP indices describing the load-bearing capacity of the surface.
