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.

Control of the semi-automatic lathe model
Loskot, Petr ; Štohl, Radek (referee) ; Macho, Tomáš (advisor)
The work introduces the concept of conventional lathes. What the main parts are and what the demands on them are. It also brings us closer to the concept of modern CNC machine tools. It presents us with the possibiliteis of motion control in the axes using modern elements and the possibility of position measurement on the axes. In the practical part, the work presents us with some possibilities of components by which the semi-automatic lathe model can be realized.
