Present state of investment casting technology
Soukupová, Lucie ; Šmíd, Dušan (referee) ; Horáček, Milan (advisor)
The Bachelor’s thesis deals with the latest trends in investment casting technology, from wax pattern manufacture, ceramic shell manufacture, de-waxing, shell heat treatment up to metal pouring and finishing operation. In the first part, the outline of the world production and the usage of investment castings nowadays are introduced. The other parts of the project include the basic technique of using new technologies. The aim of this work is developing a literature search focused on the most modern equipment and raw materials that are used in investment casting technology and testing of wax mixtures and ceramic slurries.

Solution technology of two groove guide pulley production.
Šimonek, Ondřej ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Technology deals with the production of the two - groove guide pulley for two types of semiproducts. Technological process of production solves the production of the guide pulley from the first gripping of semiproduct to handing over of the guide pulley to the warehouse. Semiproducts are two types of castings with different separating plane. The material of the guide pulley is always gray - cast iron ČSN 42 2420. Production method is cutting operation with CNC machines. The production uses tools with interchangeable cutting tips. The aim of this work is to find the most optimal method of production from both time and economic perspective and to compare the two variants.

Solution technology multiple groove guide pulley.
Teplý, Radek ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This essay discusses the production technology of multiple-grooved pulley and evaluates the technology of construction, the choice of the semi-product and their possible variations for production. The next aim is to describe the choice of production technologies, the selection of tools, the composition of technological process and the composition of different ways of chip removal during production. The essay also presents an economic of batch-production and it defines the optimal ways of production with regards to production costs.

Motor-driven roller conveyor
Seďa, Marek ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
Baccalaureate work deal with conceptual proposal powered motor-driven roller conveyor longitude 15 m, that the will transport cast given to proportions for either seats overleaf. Work is bent on calculation principal dimensions, solidity verification and generally general proposal constructional solving conveyor. Is free time type roller for transport casts saved on pallets, drive track, which will elect electric motor with gear - box. Last but not least also chain gearthat the to us will serve as driving element rollers. Baccalaureate work would had contribute by firms, companies and subjects, that the derive benefit from roller conveyor for transportation materials. She should enrich constructional possibilities solving these arrangements.

Solution technology of two groove guide pulley production.
Pokladník, Robert ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Technology compiling two groove pulley making for two types of billets. As a billets is used in both cases a cast iron EN-GJL-250. The technological process solves production of both variants from designing the billets to trans-mission to the storeroom. The production is realized through cutting operation by CNC machines. The tools are selected with cutting tip. Finaly both variants are compared from economical perspective.

Návrh rozšíření dřevařského provozu fy Vymazal v Uničově
Navrátil, Martin
The aim of this work is the proposal of modernization and expansion of the volume and range of production workshop of wooden models for casting. The thesis describes the current production operations, their sequence and the technical condition of machines. It analyzes the current problems of production, which are mainly the lack of a production area, which does not allow the production of large-size models and crossing of production flow, which slows down production. The proposal is to ensure continuity of production at its large variability and increase the volume of production in terms of its volume and maximum size produced of model equipment. Based on the analysis of production and workshop problems are suggested four possible solutions that try to optimize the manufacturing process slightly different mechanical-technological equipment and its layout. A common feature of all solutions is to move production to a newly obtained larger spaces. The solution of each variant contains suggested equipment, organization of production, the advantages and disadvantages and total estimated cost of implementation. Based on the advantages and disadvantages of all four variants of the solution is selected and recommended option, which shifts production to the new premises relatively simply and inexpensively, meets all basic requirements and allows the subsequent development of the company.
