Production technology of drill
Křehlík, Luboš ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
The work deals with production technology stepped drill of cemented carbides. Handles the basic methods and information technology grinding. Cemented carbides are becoming more frequent choice of material for processing in many industrial directions. They allow widespread use due to their mechanical and technological properties. Tools of this material are manufactured on a 5-axis grinding machines. The use of precision CNC machines enables efficient and accurate production of both simple and complex cutting tools. Software CNC machines allow you to control the 3D simulation before production begins, it's a convenient tool for checking the functionality of the program. It is also possible to establish the production of the subsequent dimensional control of the finished piece. These CNC machines and cemented carbide tools can be used for both serial and piece production.

Final machining technology of a special bearing ring using a grinder on the holes
Růžička, Daniel ; Kalivoda, Milan (referee) ; Chladil, Josef (advisor)
The main goal of this thesis is to compare 5 chosen grinding wheels, that vary by the material and structure. The testing is done in the company SLB, spol. s r.o., using a grinder on the holes BDU 80, which is set to 6 different settings of the grinding cycle, defined by the letters A´, A, B, C, D and E. These settings vary by the cutting conditions and enable to compare the tested grinding wheels by 8 measured parameters of the surface quality of the grinded bearing orbits of outer rings of the SLB 84-74 bearings, that are described by the drawing documentation.

Automation of cam shaft production
Matějka, Petr ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This thesis is intended on modernizing of grinding operations in production cam shafts of injection pump. Existing technology, mainly special-purpose machines, will be replaced by modern CNC grinding machine. Further modernization will take place in the area of measurement, where existing measuring instruments cannot measure profile of cams. There will be used the new measuring machine, which will manage to measure necessary dimensions and tolerances.

Production and sharpening tools produced on CNC tool grinder
Zdařil, David ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
The aim of the thesis is to analyze the production of tools on CNC tool grinders. The work includes the introduction of a production machine, a brief overview of monolithic tools and grinding wheels. The most important is the practical part, which is focused on the physical preparation of the tool with suitable geometry for the given application and its subsequent sharpening, the last part is devoted to the economic evaluation of the tool production.

Elimination of defects in the gears manufacturing
Petříček, Vít ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
The aim of the diploma thesis was to analyze qualitative outages in the production of gears for a gear pump and to minimize them. The largest amount of outages was caused by the burning of the surface during face grinding. After analyzing the current state of production there were created some suggestions to avoid this issue. Also there was found some space to speed up the whole process. Suggestions to eliminate burning have been tested with minimal impact on production. The reduction of outages for burned surface was achieved and also the cycle time was shortened. Those suggestions will be implemented in serial production.

Analysis of the flat surface grinding by using standard machines
Hanáček, Jan ; Dvořák, Jaromír (referee) ; Strejček, Jan (advisor)
In the first part of this thesis is discussed of the possibilities of surface grinding. There are described various methods for grinding and describe their characteristics. Furthermore, there is shown the marking of grinding wheels and is discussed of their composition and of calculating the cutting forces. In the second part of this thesis the experiment is performed. On the samples of various materials are monitored parameters of roughness after grinding, which is used by conventional grinding BPH 300 and horizontal lathe from company TDZ Turn.

Design of production technology for a grinding wheel flange
Němec, Lukáš ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
The bachelor’s thesis deals with the design of technology for the production of a component called a basic flange. The component is used for clamping the grinding wheel and is made of alluminum alloy. First there are theoretically dismantled individual production technologies, machinability and tool materials. The production technology for production in small series is designed and machinery and tooling equipment are selected. Furthermore, the bachelor’s thesis includes technological process and manufacturing instructions, which contains the cutting conditions for each tool. The manufacturing instructions are used to determinate machine time, among other things. Finally, the actual production of the component is shown.
