Suitable lubricants for deep drawing of stainless steel
Mück, Jonáš ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The intention of this thesis is the experimental evaluation of different lubricants and their suitability for deep drawing of stainless steel 1.4404. The testing method is based on the friction model at the point of drawing edge and retainers. This model corresponds with a structure of testing fixture. The suitability of every single lubricant for this application has been determined by comparison of the output, which is dependance of the strength on the track with the reference results. The testing has been performed on many different samples provided by various manufacturers. The best result was measured with the oil Kalorex AT 650 S, manufactured by AT Oil, which belongs to the group of environmentally harmful lubricants. Based on the results of this experiment we can conclude that chlorine content significantly increases the lubrication capability especially under high pressure. The modification of preparation geometry which presumes the elimination of certain undesirable disturbances accompnaying the experiemnt has been also proposed.

Design of Vacuum Clamping System for Students 3D Printer
Mück, Jonáš ; Brada, Michal (referee) ; Koutný, Daniel (advisor)
This thesis is about the structural design of the vacuum clamping worktop in a 3D printer. The first part reviews existing levels of worktops in 3D printers, their applications and extensions. Also, it describes the principle of vacuum and its technical applications. The next section analyzes the principles of vacuum and proposes a solution for its technical use. The last part describes the implementation of the optimal solution, which is applied to the student 3D printer.
