The paper describes processes of metal parts edges deburring and surface of metal samples polishing with ceramic tools based on fibre aluminium oxide. It presents the construction of basic types of tools and their practical industrial applications, and evaluates the influence of machining parameters on surface roughness. An important advantage of the used tools is the possibility of deburring and machining of external flat and shaped surfaces as well as internal surfaces and even deep drilled holes. These tools can be practically used for machining all construction materials. The results of machining of selected engineering materials, such as aluminium 5052 and 2017A, Inconel 718, non-alloy steel, in various variants of machining parameters are presented. The influence of machining parameters on machined surface roughness was described.
The paper presents the first experience of AlN ceramic surface metallization by titanium with frictional process. Using a different process conditions of friction, authors obtained various coatings (TiO, TiN, Ti). The X-ray diffraction of the substrate and the coatings of TiO, TiN and a coating of pure titanium have been presented.
W artykule scharakteryzowano procesy gratowania krawędzi i polerowania powierzchni z wykorzystaniem narzędzi z materiałów ceramicznych bazujących na tlenku glinu. Opisano konstrukcje podstawowych typów narzędzi oraz praktyczne przykłady zastosowania w przemyśle. Oceniono wpływ parametrów obróbki na chropowatość powierzchni obrobionej.
W pracy przedstawiono wybrane właściwości tytanowej powłoki metalizacyjnej wytworzonej na ceramice AlN metodą tarciową opierając się na mechanizmie powstawania połączenia, w którym energia tarcia kinetycznego jest bezpośrednio zamieniana na ciepło i dostarczana w ściśle określonej ilości do obszaru powstającego połączenia między warstwą a podłożem. W artykule scharakteryzowano tytanową powłokę metalizacyjną pod względem budowy fazowej, właściwości metalograficznych, morfologii powierzchni, struktury stereoskopowej powierzchni oraz grubości.
The article presents the characteristics of ceramic tools designed to improve the condition of the surface layer of workpieces. After milling or turning, the surface layer of the workpiece often has several disadvantages, such as burrs or uneven roughness. Brushed ceramic tools allow the surface layer to be improved as another technological step in the entire manufacturing process. The presented tests of the geometrical surface structure were made for NC6 tool steel for cold work. An analysis of the impact of brushing technological parameters on the height of unevenness and visual features of the machined surface was carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
