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.

Machine grinding
Beseda, Vojtěch ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
At the beginning of this dissertation an overview of grinding technologies is presented. The following chapter presents a selection of grinding machines from databases and manufacturers’ catalogues. At the end, a case study of grinding processes in a small manufacturing company is analysed. It focused on the action of grinding an internal cylindrical area on thin wall housing. The solution is the adaptation of component´s attachment, the adjustment of the working cycle and the dimensional control according to drawings.

Proposal of Technologies for Components Guide Screw and Nut
Staník, Štefan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis describes the design technology for the production of guide screw and nut tool carrier for mechanical lathe SV 18 RA. The batch size is 200 units per year and production will be carried out on conventional machines. For the production of the guide screw will be used steel ČSN 411700.1 and for the nut a copper alloy ČSN 423123. To produce the components were processed manufacturing drawings, technologicall process of producing the two components and design of machines and tools. At the conclusion it has been incorporated economic evaluation of the whole production.

Design of Device for Regrinding of Specimens
Matečka, Martin ; Nečas, David (referee) ; Smejkal, David (advisor)
This bachelor thesis is focused on design of device for regrinding of specimens. In the first part is described grinding technology, cutting conditions for grinding of outer cylindrical surfaces and kinematic and dynamic phenomena arising in these conditions. There are also analyzed the grinding tools and their using. In the next points are described the designs of the grinder’s basic components. The last in this chapter is described the testing device on which the specimens are tested. The next chapter is focused on description of the objectives and analyzing the problems. There are described the variants of design solutions. After assessment of advantages and disadvantages of all variants is selected optimum design solution which is detailed described in the last section.
