Finishing machining of hard-to-machine materials
Filípek, Timotej ; Varhaník, Matúš (referee) ; Píška, Miroslav (advisor)
The Master‘s thesis focuses on processing of hard-to-machine materials by the finishing machining methods. The first chapter comprises division and characteristics of finishing technologies in the field of machining processes. The chapter following includes division and characteristics of the hard-to-machine materials. The experimental part – another significant part of the thesis – is focused on grinding of mostly bearing rings made of hard-to-machine materials. The aim of the experimental part is to compare and subsequently assess the use of various kinds of grinding wheels in the grinding process of a given workpiece material. Several parameters are examined from the technological and economic point of view. The assessment of the experimental part provides an overview on the advantages and disadvantages of the use of the grinding wheels in the grinding process of a given material for large-scale production. The conclusion is a summary of the results obtained in the experimental part.

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.
