Novotný, Petr ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma thesis deals with legislative purposes for the operation of machinery in the Czech Republic and the European Union. It deals with the analysis of technical standards of machinery, specific machining centers. The analysis of the risky machining center NHX 5500 DMG Mori is based on this. The result of the work is the minimization of ongoing risks and meeting the legal requirements of the state of the operated machining center.

The Rationalization of Production Part of Injection Pump
Havel, Marian ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This thesis focuses on the rationalization of the production process of plungers and elements of injection pumps in relation to improving the quality of the final products. Today’s technology, which mainly uses single-purpose machines where the production quality markedly depends on the abilities and activities of the operator, will replaced by modern machining centres and CNC machines for grinding all functional parts of the plungers, coupled with modern measuring devices. These production machines with the support of measuring devices will improve the productivity of production and the general quality of the produced components.

Large Turning Centres
Nábělková, Irena ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
This bachelor's thesis is dedicated to large turning centres. The first part thesis is the summary of large turning centres, their description and types. Usage possibilities of different large turning centres in cutting operations are mentioned too. In the second part, the calculating proposition of a chosen component of large turning centre is solved. This component is spindle-drive. Calculating proposition contains calculation of cutting force, power, total efficiency, utile work and energy.
