Design of headstock for boring centre
Kovács, Zdeněk ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The aim of this bachelor thesis was to do the design of headstock used in horizontal boring centre. At the beginning was carried out the search of important headstock parts which are found in horizontal boring centres. After that was dealt with automatic tool change. The last part this thesis concern with design of headstock and its realization in 3D.

A Project for the production of the transmission case for the winch
Hrbáček, Emil ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
The project elaborated within engineering studies. The project is submitting design of technology production of precise holes for rolling bearings which are located in transmission case for the winch. Variants of production technologies were designed based on the construction drawings of transmission case. Chosen type of technology is boring. Boring was performed on the CNC machine DMF 180 produced by DMG MORI. DMF 180 allows precise production of bearings holes. Via selected criteria, it was selected the better variant of two. The criteria were: cylindricality, cohesiveness, position of elements and surface quality.

Roller burnishing tools in engineering.
Henzl, David ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This bachelor work deals with chipless technology of roller burnishing and tools with bearing on roller burnishing of circular orifices and back-to back surfaces. In the first part of the work elementary conections concerned with finishing and hardening of machine components by roller burnishing are explained. In the next part the classification of tools produced by German company Baublies AG is realised. In the following part there are examples of roller burnishing method utilization in the machine industry. Hereafter, the technical – economical evaluation and comparation with conventional methods of finishing such as lapping, honing, superfinishing, polishing, grinding, core – drilling and reaming, boring work, diamond burnishing and shot peening is realised. In the conclusion of the work the assumptions for the future are given.

The design of plate horizontal boring mill
Vondrák, Pavel ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
This master's thesis describes a design of horizontal boring mills. The first part is dedicated to description of the various types of these machines and their accessories. There are also described drives and linear guideways. There is a list of plate horizontal boring mills of Czech and foreign producers. The second part of this thesis deals with designing of comlete machine's bed and its slides (X-axis). Casting of the bed and its slides are designed for universal machining to the use of rolling or hydrostatic guideways. The drive of X-axis is also designed and it works in master/slave mode. The final result of this master's thesis is a 3D model of the machine in two variants, with hydrostatic and rolling quideways. Machining drawings of the bed for both variants are attached to this thesis.

Solution technology of part "víko" in the condition of a middle-sized company
Kavan, Petr ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is concerned with evaluation of actual production technology of part “hydraulics cover” and with design of new, progressive variation machining of this part. Solution is focused at first on rationalization of cutting tools and choice of suitable cutting tools. An effort is to achieve shorter production time and decrease costs on production of component. With this problem is related alteration of technological documentation and technical economic evaluation for determination return rate of investments into progressive cutting tools.
