An analysis of the heat-affected surface layer after grinding of the bearing rings
Filípek, Timotej ; Kalivoda, Milan (referee) ; Jaroš, Aleš (advisor)
The object of this bachelor thesis is a determination of the causes of burns origin at the surface layer of a workpiece after a grinding process and their elimination. The first chapter is focused on the description of the grinding technology, grinder types and grinding tools. The second chapter deals with the characterisation of the process fluids, their use and suitability depending on the cut conditions and the material. The third chapter explains what a burn is, the causes of its origin and the ways of subsequent elimination of this adverse event. The experimental part – performed in the Schaeffler Skalica, spol. s r.o. company – deals with the origin of the heat affected surface layer due to improper dressing grinding parameters and improper choice of intervals between dressing processes of the grinding wheel. At the experiment two different grinding wheels were used; subsequently, they were compared to each other from the point of view of suitability for the machining process. The final chapter comprises the experimental part assessment and a summary of the findings in this topic.

Proposal for Universal Clamping Fixture Production
Košútová, Katarína ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
Bachelor thesis deals with the production concept of universal fixture designed for a small beamhouse. The thesis is divided into parts which follow each other. The thesis describes the machining technology. The practical part includes the production concept of a universal fixture in paper form made in parametric modeling program called SolidWorks. In the end od practical part is a production of universal fixture and assembly. The last part contents of a technical-economic evaluation and comparison of production.
