Semi Automatic Lathe Machines
Chytil, Jakub ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This thesis deals with the background research, description and division of semi-automatic lathe machines. One of the thesis’s tasks is to realize the computational concept of a particular machine component. The beginning of the thesis focuses on the principle of lathe turning, the basic calculations, brief description of lathe blades, the main parts of semi-automatic lathe machines, and kinds of semi-automatic lathe machines. There are described machines of contemporary production with their main parameters and manufacturers in The Czech Republic and in foreign countries further on. The final part of the thesis is addressed to calculation of spindle deformation and optimal distance between the Bearings.

Design of turning machine C axe
Jeník, Jan ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The subject of this thesis is the construction of turning machine C axis. The first part of this work includes a search of possible methods of construction drive C axis. The second part includes a choice of drive parameters, conceptual proposals for possible solutions and selecting the most appropriate variant. Also included is a 3D model of the lathe spindle with the C axis, modeled in SolidWorks 2007 and assembly drawing of spindle with C axis.
