Suitable lubricants for deep drawing of steel
Hřebíček, Pavel ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The aim of this work is experimental evaluation of suitability of lubricants for drawing of stainless steel 1.4301 at elevated temperature, which corresponds to temperature in real process. The lubricant testing method is based on friction modeling between the pull edge and the retainer, which corresponds to the real process. Therefore, the design of the test fixture also conformed to this model. The result of the work is a comparison of the suitability of every single lubricants with the reference lubricant used in ACO Industries. The best results were obtained with AT Kalorex 650 S lubricant, which contains environmentally harmful additives.

Design of production technology for a bearing pin
Bocek, Bogdan ; Kalivoda, Milan (referee) ; Sliwková, Petra (advisor)
The bachelor's thesis deals with the production of a rotary component – a bearing pin. First, the component itself, its dimensions and material are solved, and then a suitable semi-finished product is selected. The research focuses on the production technologies used. In the next part, the production technology of the bearing pin is proposed. The technological process consists of selected production machines and tools, production process and production control of component, including gauges used.
