Design of spindle turning center
Krajča, Martin ; Knoflíček, Radek (referee) ; Pavlík, Jan (advisor)
This master´s thesis deals with the design of the headstock of a turning center. The aim of the work is the design solution of turning headstock with output of about 5 kW with the possibility of positioning in the C axis. The introductory part of this thesis is focused on the descripti-on of the basic parameters of the headstock and turning centers on the market. The next part deals with choice of cutting conditions and calculation of spindle parameters. These calculations are verified using the FEM method. Based on the calculations and design requirements, a headstock model with drawing documentation is created.

Design of multi-functional machining centre
Sedlák, Pavel ; Holub, Michal (referee) ; Blecha, Petr (advisor)
This master thesis deals with the construction of multi-functional machining centre. The theoretical part describes the history of lathes, trends in production of lathes and individual machine parts. The practical part is the structural design of the spindle with positioning in the C axis, the second spindle (including drive in Z axis) and the turret (including drive in the X and Z axis). A 3-D model of the entire lathe assembly modeled in Autodesk Inventor 2010 is also included.

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 cartridge spindle for turning machines
Žádník, Lubomír ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The diploma thesis deals with the design of a built-in headstock of a turning center. The aim of the work is the design of a spindle for machines up to 10 kW. The spindle is driven by a two-speed gearbox and a belt drive. In the introduction, the work deals with the description of individual parts of the turning headstock. A design proposal is performed, accompanied by a number of technical calculations. The result of the work is a 3D model, drawing documentation and calculation report.

Design of spindle for a small lathe
Šatný, Patrik ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The thesis deals with the design of a headstock for a small lathe. The first part of the thesis deals with the description of individual structural nodes related to the construction of machine tools headstock. The second part includes an overview of similar machines available on the market. The final part deals with the calculation of necessary parameters, the verification of results using the finite element method and the construction of the proposed headstock. Based on the designed construction is created 3D model and drawing documentation.

Dynamic Behaviours of the C Axis Drive for Multifunction Cutting Center
Křepela, Jan ; Marek, Jiří (referee) ; Souček, Pavel (referee) ; Brychta, Zdeněk (referee) ; Singule, Vladislav (advisor)
his Disertation thesis involves the creating of the simulation model of the C axis drive over mentioned machine and them verification on the prototype of this machine. C axis is controlled with position feedback. Simulation model was created before the realisation of the machine prototype for the preliminary identification of the dynamic behaviours in the working cycles and them opportunity of the realisation this conception. C axis is constructed with worm gear and is controlled with help of Master-Slave drive. This torque drive eliminates the production backlash in the worm gear. The multifunction turning center, where is used this C axis, is determinate for heavy duty roughing cutting of the forged peaces, where is problem with dynamic stability of the cutting process. Simulation model includes the problems with multi-body mass system, friction on the worm gear, self locking, damping on the worm gear and the optimization of the parametrs for many regulators. Simulation model was verified on the prototype of the machine. Achieved results bring the new knowledge, which are used for simulation complicated machine nodes and this knowledge is used for research and developing of the similar mechatronics system.
