Design of spindlespeeder
Závada, Otakar ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This bachelor thesis deals with conceptual design of high speed spindle based on cutting conditions. Research part of thesis describe each types of high speed spindle based of their drive. Next chapter are documented cutting conditions which are corresponded with experience. High speed spindle faced these act most of the time. Cutting conditions show output conditions of planetary gearbox which is described in next part of thesis. All the experience are used in conceptual design. The drawings contains of assambly drawing and drawing of selected components. The drawings are based on model made in 3D CAD system

Advantages and disadvantages of clamping the workpiece with zero points
Jirků, Kateřina ; Tůma, Jiří (referee) ; Knoflíček, Radek (advisor)
This bachelor's thesis deals with a technical-economic analysis of whether the purchase of zero point clamping system is economical. It compares the advantages of the zero point system both to standard clamping devices and to each other. It also compares brands and their dealers to the Czech Republic. Finally, this technology is evaluated by calculating the return after the application of zero point clamping system on shop floors of Soma Ltd based in Lanškroun.
