Diamond wheels and their use in the stone industry
Skryja, Jan ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with stone sawing during stone processing. It is divided into theoretical and practical parts. In the theoretical part diamond blades, the sawing process and stone extraction are described. The practical part is focused on the wear of circular saws in granite circular sawing. The wear is determined for two diamond cutting blades made by different manufacturers and is determined by the blade weight loss and segments height loss as a function of time. Both measured values show linear dependence. The results are the basis for a future comparison of the two diamond blades on the economic side, which is not the subject of this work.

Prediction of cutting forces and powers when sawing with a circular saw
Skryja, Jan ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This thesis deals with the cutting of steel thin-walled parts by slitting saw. Its subject is to study and test of cutting edges of slitting saws with a goal to reduce cutting forces to a minimum. The thesis is divided into the theoretical and practical part. In the theoretical part, existing knowledge about slitting saws and general cutting technology is analyzed. In the practical part testing of four slitting saws with different geometries of cutting edges during machining of chosen thin-walled part is performed. The performed measurements show that by the proper choice of the geometry of cutting edge, the cutting force can be reduced approximately by 30 %.

Credit market in the Czech Republic
Skryja, Jan ; Smrčka, Luboš (advisor) ; Schönfeld, Jaroslav (referee)
The thesis discusses current situation in the credit market in the Czech Republic. The main objective is to describe the functioning of the mortgage market and other credit markets, aiming not only to finance their own housing, but also on non-purpose loans. Business loans will be mentioned only very strictly. Loans are so extensive topic that it deserves a clear explanation, which families and individuals will understand and what they can expect when they will solve financing or what products are offered, what these products actually mean and what life situation (with regard to creditworthiness of the applicant, the purpose of the loan, and many other aspects) are determined. The whole thesis not only describes how the credit market looks, but also practically demonstrates how the entire process of handling the loan looks like and what you need primarily to solve when dealing with the financing.
