Efficiency improvement proposal of machining specific components of pneumatic cylinders
Židlický, Ondřej ; Chladil, Josef (referee) ; Sedlák, Josef (advisor)
This Master thesis aims to increase the effectivity of the machining of pneumatic cylinders specific components. In the first chapter, the concurrent approach to the manufacture of corrosion resistant austenitic piston rod. This approach consists of the technological procedure, the analysis of the cutting tools used in the process and the cutting conditions. The machining process deals with low durability of cutting tools and the necessity of continual supervision by the operator. Therefore, an alternate design of cutting tools and cutting conditions is suggested in the next chapter. The new design has been tested in manufacture process. In the last chapter, the concurrent and the innovative approach are compared. By choosing the proper cutting tools and cutting conditions it was managed to increase the durability of cutting tools and to increase the effectivity of the whole manufacture process.

Repair of a holder for grinder cover
Židlický, Ondřej ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis is focused on the repair of a holder for a grinder cover and the manufacture of the missing pieces of a pedestal grinder. The structurally-functional analysis of the machine and the manufactured pieces is described in the first chapter of this thesis. The manufacturing process itself is described in the following chapters. Raw materials and production technology are designed for the manufactured components. For each component, there are described the technological processes and instructions. The junction of the new parts of the machine with the original ones is conducted through welding. After this operation, the whole grinder cover is sandblasted and its surface is sprayed with a protective layer of lacquer. Next, the grinder cover is mounted to the pedestal of the grinder. The whole manufacture design is considered from the technological and economical point of view in the penultimate chapter and the drafts for improvements are described in the last chapter. All of the components are manufactured in accordance with the design and the grinder is once again in good technical condition.
