摘要：

The article proposes a "stock" - an improved technological process of parts production. During the research it was found that the reason of the failure of hydraulic cylinder is charged rod surface, obtained after the grinding process. This factor leads to intensive wear of the sealing system and subsequent depressurization of hydraulic cylinder. It is possible to eliminate this problem by replacing the grinding process with mechanical treatment with improved dynamic characteristics. It will ensure the macro- and micro-geometric characteristics of surface. One of the main reasons for the deterioration of surface roughness and accuracy is the accumulation of self-oscillation energy, depending on the alternating stages of the chip formation process. The method of high-energy laser irradiation will allow reducing the influence of self-oscillation process on the macro- and micro-geometric parameters.
