Surface treatments of internal combustion engines cylinders
Malec, Petr ; Raffai, Peter (referee) ; Maršálek, Ondřej (advisor)
This bachelor thesis is a professional research, which describes the most common methods of surface treatments of modern internal combustion engines cylinders. The work consists of the distribution of the species changes, their use and justification of their application. It also describes the technology of individual surfaces, their coating and finishing operations to achieve the best results of sliding surface.

Analysis of machining finishing methods
Urban, Martin ; Chladil, Josef (referee) ; Osička, Karel (advisor)
This diploma thesis deals with the analysis of finishing machining methods. The work describes the technologies of grinding, honing, lapping, polishing, tumbling and superfinishing. Furthermore, the residual surface tension after the superfinishing method is analyzed and two possible methods of its measurement are described. An experiment was also performed in which the finishing processes for the bearing spherical roller for axial spherical roller bearing 29434EJ-3, the bearing spherical roller for double row spherical roller bearing 23164CJ-3 and the inner bearing ring for double row spherical roller bearing 22224EKJ N7-2 were described. Six surface roughness measurements were then performed on the surfaces of these components. For the 23164CJ-3 barrel, the mean arithmetic deviation Ra of the profile ranged between 0.59 and 0.70 µm, for the 29434EJ-3 barrel, the Ra value ranged between 0.26 and 0.31 µm, and for the 22224EKJ N7-2 inner bearing ring, between 0.22 to 0.28 m.

Roller burnishing tools in engineering.
Henzl, David ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This bachelor work deals with chipless technology of roller burnishing and tools with bearing on roller burnishing of circular orifices and back-to back surfaces. In the first part of the work elementary conections concerned with finishing and hardening of machine components by roller burnishing are explained. In the next part the classification of tools produced by German company Baublies AG is realised. In the following part there are examples of roller burnishing method utilization in the machine industry. Hereafter, the technical – economical evaluation and comparation with conventional methods of finishing such as lapping, honing, superfinishing, polishing, grinding, core – drilling and reaming, boring work, diamond burnishing and shot peening is realised. In the conclusion of the work the assumptions for the future are given.
