Design of elongated right angle milling head for horizontal boring machine
Svoboda, Ondřej ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
This thesis deals with design of right-angled elongated milling head for horizontal boring machine of FERMAT production. The thesis includes a detailed research of milling heads, a description of the head´s basic components and certain commercially available head´s comparison. Design part is describe components description and the design. Calculations are focused on determinating of forces generated during machining, setting of loading spectrum and the power load calculating individual gears during machining. In the next part is calculation of the reactions in the spindle bearings included, the equivalent load and durability of spindle bearings, spindle deformation and spindle bearings optimum distance. The thesis also includes spindle strength calculation, horizontal and vertical shafts analysis, gears design with helical teeth and gear strength. The thesis describes the design of extended milling head and particular design nodes which is supplemented by the 3D model. In this thesis is also included a drawing of assembly and components.

Design of acceleration head spindle horizontal boring machines
Tocháček, Jakub ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with conceptual design of spindle speeder head for headstock of horizontal boring machine of FERMAT Company. The thesis includes research part, which is initially given to horizontal boring machines and their accessories and continues with an overview and comparison of spindle speeders that are currently on the market. The work includes technical report, which is aimed on design of the belt drive including the idler pulley. Design of belt drive is based on the output of the calculation program developed by manufacturer of synchronous belts. Calculation part, mainly focused on the spindle and its bearings, is preceded by a part in which are calculated cutting forces for two technological operations. Calculation of the spindle part contains strength calculation of the spindle and equivalent basic rating life of spindle bearings, including calculating of radial stiffness at the spindle nose and calculation of optimal distance between the spindle bearings. At the end of the technical report is a financial summary, description of used components and the chosen design solution. The drawings which are based on model assembly processed in 3D CAD system, contains a drawing of the entire device and drawings of selected components.

Design of a manual milling head designed for technological operations on medium heavy workpieces
Nedbal, David ; Pavlík, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with mechanical design of right-angle manual milling head for headstock of horizontal boring machine of Fermat production. The thesis includes research of milling head types, Fermat production heads, but also heads of competition companies with similar parameters like designed head. Design part of thesis is about describing used components of chosen solution. The thesis includes also technical report describing calculation of load spectrum from machining, design of gears, calculation of reactions in spindle bearings, spindle deformation and control of spindle bearings. The end of the thesis describes financial evaluation including also comparation with competitive milling heads with similar parameters.
