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.

Active Balancing of Machine Tool Spindle Units
Pěnčík, Martin ; Vetiška, Jan (referee) ; Březina, Tomáš (advisor)
The aim of this bachelor’s thesis is to do background research of active balancing, to design a simplified model of spindle with an active balancing system and to realize searching simulations. The research describes basic terms and methods which are necessary to understand the issue of balancing. Then, the principle of both classic and active balancing and the description of an active balancing actuator are stated in the paper. Moreover, the thesis presents the creating process of the model which was performed in the program Matlab/Simuling. The thesis presents detailed descriptions of the realized simulations, the results of the simulations and a subsequent result analysis.

Design of grinding spindl
Slavíček, Josef ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
The subject of this bachelor thesis is the construction of grinding machine spindle. The work is divided into two main parts. The first part is engaged with the general description of the spindles, their design components, the accuracy requirements and modern trends in the spindles. The second part is engaged with the design calculations of selected grinding spindle. The conclusion of this work is drawing and 3D model of that selected spindle, is created by using Autodesk Inventor 10.

Design of milling spindl
Voda, Pavel ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
The aim of this thesis called Design of milling spindl is research and description of milling spindles. The first part is focused on general description of spindle. It also includes brief overview of milling machines manufacturers and description of the basic spindle parameters. The second part lists factors affect design of spindle. The following is proposal of spindle. There are selected parameters and performed necessary calculations. 3D model made in Autodesk Inventor and assembly drawing is parts of supplement.

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.

Description of tool clamping interface at milling machines
Huňka, Radek ; Opl, Miroslav (referee) ; Pavlík, Jan (advisor)
This bachelor’s thesis deals with problems of tool holders. The thesis covers the standard types and potencys holding of toolholders in spindle machine. The toolholders are ranked from construction and function direction. Further deals with division and description of some types of mechanism tooling tool in toolholders, their construction and using.

Description of drilling machines
Legutký, Lukáš ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This work focuses on description of drilling (boring) machines. The main thing is to describe machines and their construction along with new possibilities of modern age. Companies that have a strong position on market will be presented and a calculation of a spindle will be interpreted. This thesis is consisted of four parts, beginning with the machines description, through the presentation of companies, to the characteristic of spindle and illustration its calculation. At the end there is a total summary.
