Design of small CNC milling machine
Rajdl, Filip ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
The bachelor thesis deals with the design of headstock, spindle and Z axis of a small CNC milling machine. Firstly, the current state and production of small CNC milling machines is described. The other contains a system analysis of the given issue. Then input parameters are selected to be used for the necessary calculations. The last part of the thesis contains the structural design of the headstock and spindle with Z-axis feed, which is created in Autodesk Inventor. It includes a 3D model, assembly drawing, and production drawings.

Design horizontal exchange of the head - VA1-C
Vyplašil, Jan ; Holub, Michal (referee) ; Sýkora, Jan (advisor)
Diploma thesis deals with the concept of interchangeable straight spindle head type VA1-C, used for automatic clamping in 80 kW spindle head from production of TOS Kuřim. Thesis contains survey of interchangeable heads, analysis of the spindle housing, strenght analysis of the spindle with the safety calculations in critical sec-tions and analysis of the clamping mechanism together with the calculation of the camping force, which holds the tools in the spindle. Analysis of the camping mechanisms contains calculation of the contact stress between balls and housings. All results are shown in the graphs. In the last part of the thesis are described the construction elements using the model of the interchangeable head. Enclosed is the assembly drawing of the spindle head, bill of material, detail drawing of the spindle and also 3D model of the interchangeable spindle head.
