Micro-turning applications in high precision manufacturing performed by diamond tools
Švorc, Josef ; Dvořák, Jaromír (referee) ; Žídek, Jan (advisor)
Bachelor thesis is focused on micro-turning. The work takes the form of a literary research, which aims to make an overview of the production technology. First, it deals with the definition of the topic itself and with the physical properties and phenomena that occur during micro-machining. Then it discusses the construction of micro lathes and their division into categories and compares them to each other. It also deals with the cutting tools suitable for this machining process and their production and shaping. The last part of the thesis is focused on the application and utilization of micro-turning in industry and on the creation of non-rotational components and micro-structures.

Cemented carbides and theirs effective use
Dembek, Jiří ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This diploma thesis is aimed on cutting tools made of cemented carbides. It characterizes marking, production and properties of non-coating and coating cemented carbides and describes the latest trends in coating. Target of this diploma thesis is comparison of assortment of two important world’s producers and one Czech producer in term of used productive technologies, products microstructure, coatings types, coatings methods and possibilities of their usage. Cutting data were evaluated and compared from obtained technical knowledge, which were recommended by chosen producers for effective turning application of their cutting tools. Recommended cutting speeds were found out for specific type of cutting material according to ISO, width depth of cut and for specific values of feeds per revolution.
