Hand tools for renovation purposes
Klika, Jiří ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Diploma thesis deals with renovation of tractor Zetor 6911 with hand tool machining use. Theoretical part aims at historical evolution of machining and describes the hand tool machining methods. Renovation options include repair by a renovation company, yourself renovation and yourself renovation with cooperation in external company. Due to great renovation experience and technical knowledge is tractor chosen to be renovated by yourself. Complete machine renovation is very complex thus there are shown only specified examples of machine parts renovation. In the thesis there are in detail described renovation processes, including tools and hand devices. Final part includes results evaluation and costs comparation of renovation options.

Application of Surface Treatment on Hand Tools
Vraspírová, Eva ; Klakurková, Lenka (referee) ; Doležal, Pavel (advisor)
Bachelor's thesis deals with problems of materials, which are used to production of hand tools and implements. The theoretical part is focused on tool steels, their mechanical and technological characteristics and to their heat processing. Below there are well-arranged and described surface modification, which are applied to materials nowadays. The next part is focused on modern technology of surface modification, which are applied to hand tools. The research is mainly focused on technology of production of bits by company Wera Werk Ltd, which is deal with production and distribution of hand tightening tools, such as screwdrivers, angular keys, plug keys, bits and torque tools. Attention is also paid to technology of surface modification, e.g. based on zinc phosphate, nickel, nickel-gold and nickel-diamond-gold, used for these tools and to problems of painting. To elements interaction study light microscopy, the hardness measurement by Vickers and Brinell and scanning electron microscopy equipped by energy dispersive microanalyses.
