Manipulator of Tools used for vertical tool magazine
Fiebiger, Radek ; TOSHULIN, Pavel Rumplík, (referee) ; Novotný, Lubomír (advisor)
The aim of this thesis is to design different variants, choose an optimal one and the constructional solution of a tool manipulator for vertical lathe from SKG line by TOS HULÍN a.s. This thesis also includes technical and economical report. There is a solution of a basic conception, main dimensions, functional calculations and calculations of rigidity of chosen parts of this manipulator. All computations and methods are in accord with valid standards.

Planetary Gear Box Used for Drive Table of Vertical Lathe Driven by the Direct Drive Engine
Žila, Slavomil ; TOSHULIN, Milan Lutonstý, (referee) ; Novotný, Lubomír (advisor)
The main theme of this thesis is an analysis, desing and construction of a planetary gearbox used for a drive of a vertical lathe table. The theoretical part of the thesis describes fundamental features and terms of planetary gearboxes and torque motors. In the next part of my work I design loose functioning of toothing. The calculation part of my work is processed in accordance with technical standards. The practical part of my work deals with a description of the project and the implementation of the device. The drawing documentation is processed with Cad system and it includes general assembly drawing and drawings of the three important components.

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.

The drive of the feed coordinate portal machining center through pinion and rack
Malásek, Petr ; Novotný, Lubomír (referee) ; Marek, Jiří (advisor)
This thesis is dealing with determining of technical and economical limits of axis X of portal milling machine driven by gear rack and pinion. And designing drive of axis like this. In chapter overview of the current state of knowledge are researched options of drive systems of linear axis, primarily of using ball screw and couple of pinion and gear rack. Basic parameters of axis X portal milling machines, options of measuring, guiding of axis and electric motors. Then the limit suitability of using pinion and gear rack is determined. In next chapters is designed few variations of arrangements of drives and selected the best one. This arrangement is then designed.

Exhausting devices used for multi purpose machining head
Bajza, Stanislav ; Učeň, Oldřich (referee) ; Novotný, Lubomír (advisor)
This thesis deals with a design of exhaust mechanism used for a machine tool made by TOSHULIN a.s. The device itself is designed to extract dangerous dust that is produced while machining composite materials out of machine workspace. The main task lies in the design of kinematic scheme for tubing from filtration unit to the front of the ram without compromising the abilities and workspace of the machine. Following that it deals with the design of the end-nozzle used to seal the workspace around the workpiece.
