Design of tool turret for CNC lathe
Navrátil, Lukáš ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis deals with mechanical design of tool turret for CNC lathe. The first part of the thesis is dedicated to research of automatic tool exchange and current trends in design of tool turrets with drive of rotary tools. The second part is focused to design of tool turret, which is based on the findings of the research part of the thesis. The design includes calculations of machining loads, spindle deformation, bearings, gears and spindle startup. Furthermore, 3D models and selected drawings are included.

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.

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.

Headstock and main spindle of horizontal turning center
Suda, Martin ; Novotný, Lubomír (referee) ; Dokoupil, Vladimír (advisor)
The thesis deals with headstock and spindle of the universal turning center. In the introduction part is a destription of the headstock morfology. It describe how the spindle and headstock can be solved in terms of its bearing, installation, used clamping interface, lubrrication, cooling and sealing. The second part is devoted to the universals turning machines which are available on the market. In the final part is the practical solution of the headstock and spindle on which can be performed for milling and drilling operation instead of turning.

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.

Production of a bolt on CNC lathe
Kališ, Jiří ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis treates about aplication coupling bolt in energy power industry. This coupling bolt is used as a coupler of flange shaft on the turbine with generator. Work developed in the bachelor degrees addresses application of this coupling bolt and technological proces of the component production order by foreign client. There is also described mounting and disassembly of this coupling bolt. According to the needs of client is used material 34CrNiMo6, persuant to germany marking DIN 1.6582. Then coupling bolt is made by using CNC lathe and after that are made nondestructive tests.

Technological process for part flange
Král, Zdeněk ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
In This thesis the technological process for part flange is compiled. The thesis inculdes analysis of component, material choice and choice of semi – finished product. Two technologies of production have been choosen. The production on the universal center lathe and the production on the CNC lathe. In another charter calculation times are being disscussed. Lastly the technical-ekonomic evaluation is pictured, which contains the comparison between two technologies of production.
