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.
