Draft of spacer production technology
Zíka, Marek ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
The diploma thesis deals with the design of a new technological process for the production of a spacer ring with a diameter of 212 mm in cooperation with the company Meopta – Optika, s.r.o. The production of this component according to the current process does not comply with the prescribed geometric tolerances of flatness of the face and radius runout with a tolerance field size of 0.005 mm. The work is a detailed analysis of the specified component and describes the current technological process, including the machines on which the spacer ring is manufactured. Based on the knowledge gained from the analysis of the current process, a new technological process was created. During the production according to this process, some geometric tolerances were also exceeded, but the values exceeding the prescribed tolerance field were significantly reduced. The department of production technology found the results to be sufficient and the spacer ring will be produced according to the new technological process. In the last part of the work are the costs of production of components according to both processes.

Production, structure, mechanical properties and usage of martensitic stainless steels
Zíka, Marek ; Myška, Martin (referee) ; Blažík, Petr (advisor)
This bachelor thesis deals with issues of production, mechanical properties and structure of martensitic stainless steels. Further a thesis is focused on heat treatment, which significantly improves mechanical properties of steels, and usage of this materials. In experimental part is solved influence of chromite sand on surface structure cast. On the images of structure of casting samples can be seen, that the chromite doesn’t have influence on surface structure.
