In this paper was presented the aspect of stress in the top layer part shaped in a hybrid technology, where the elements are first milled and then burnished. Stresses in the surface layer play a very important role because they are responsible, among others, for the development of cracks, corrosion and cavitation. Characterization and stress research in the surface layer allow prediction of parts behavior exploitation. During the research was confirmed the being of positive, compressive stresses in the surface layer. For the different diameters of the burnishing balls there were significant differences in stress values due to the variable pressure value at the same value of the burnishing force Fn.
