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.
