Lubricants created by nature
Drobilič, Ivo ; Urban, Filip (referee) ; Nečas, David (advisor)
This bachelor thesis provides an overview of substances which can be considered as the lubricants in its natural environment. The first part of the thesis of focused on lubricants in human body. The substances such as water, blood or synovial fluid are analysed in a detail. The following chapter deals with lubricants in everyday life. As the example, decrease of tyre adhesion in case of rain or longer breaking distance of trains as a consequence of presence of leafs on rails, can be mentioned. The last part, in addition, summarizes the lubricants which are based on natural products.

Study of More Efficient Manufacturing Technology for UniGear Doors
Drobilič, Ivo ; Kalina, Emil (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with the analysis of suitable technologies to produce the switchgear door of product UniGear with a design of more efficient production technology. Thesis is divided into four main chapters, in which the first part describes the doors of individual switchgear compartments, design of door materials, technology for achieving desired shape of a base plate, possibilities of sheet metal forming and other technologies not linked with sheet metal processing. The second part of the thesis deals with study of the whole current production process of doors in ABB s.r.o. from sheet metal processing till powder coating. The thesis also contains proposal of innovated production technologies with a selection and evaluation of the final variant with technical and economic evaluation of current and proposed solutions.
