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 lathe spindl
Švarc, Pavel ; Bilík, Martin (referee) ; Blecha, Petr (advisor)
Bachelor thesis is focused on one of the most important parts of lathe – spindle. Thesis is divided into two main parts. First of them is focused on the short research, which contains general information about spindles. This part deals about steps, which are needed to be done in construction for the correct function of spindle. At the end of first part is short presentation of chosen companies and their products. The second part is focused on the proposed spindle calculations. Into this part is also involved 3D model of proposed spindle and his assembly.

Lathe spindle
Zábojník, Petr ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
Bachelor’s thesis will be talking about one of main parts of lathe, about spindle. In first part I’m going to make a research in this subject. I will mention about a history, development and types of lathe. Following lines will be about function of spindles and their separation in terms of drive. I’m also going to focus on the impact of toughness and precision of the spindle imposition on machining accuracy. Conclusion of the first part will be fulfill with the selection of bearings, methods of work holding, lathe manufacturers and types of lubricating. The second part will be designing of spindle itself. Complemented with an assembly drawing and 3D model.

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.

Turning tools
Václavek, Jiří ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
The bachelor's thesis deals with turning tools and compares domestic and foreign companies' products. The turning is generally described with basic formulas in the first part of the thesis. The second part is aimed on tools, categories of tools and materials which they are made of. In conclusion, there is comparsion of several tools from domestic and foreign producers.

Design of turning machine
Pařík, Zdeněk ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
The submitted bachelor thesis deals with the construction of a small turning machine for metal cutting, designated mainly for a home usage. A part of the thesis is also a recherche of turning machines of the same category, which are sold on our market. In the thesis, there are resolved basic constructional problems in range of the project and optimalization of the parameters according to the needs of this small machine. To create a 3D model of this turning machine, 3D modeller SolidWorks 2004 was used. From the created model there were generated assembly drawings sequentially that are enclosed to this thesis also in printed copies.

Description of machine tool frames.
Míčka, Martin ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
This work describes the machine tool frames via background research. There are basic requirements for the frames included in this work. It is focusing especially on static and dynamic rigidity. Thereinafter you can find in my work all the ways of making the frames and also the materials which are used during their production. Last but not least I am presenting some examples of constructions single parts of the frame and all the ways of their attachment to the ground.

Description of lathe machines
Bašek, Ondřej ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
This thesis is concerned with sorting of horizontal lathe machines and description of their individual parts. Some examples of horizontal lathe machines are introduced here and are also distributed according to different types. Description and characteristics of the individual lathe machines are named. The thesis is concerned with the lathe machines of present world production.
