Linear feed systems in construction of machine tools
Kolaja, Radim ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
This bachelor thesis deals with the detailed description and division of constructional componets composition of linear feed systems, which are essential part in the construction of machine tools in the manufacturing process. It describes individual subsystems, which are described in details and compared in terms of favorable and unfavorable characteristics for certain working conditions. Out of these possible ways of implementation of linear feed system is initiation one example with an overview of the basic calculations used to design project.
