Investigation of the Usability of Cubic Boron Nitride Cutting Tools as an Alternative to Diamond Cutting Tools for the Aircraft Industry

Abstract

Diamond and cubic boron nitride (cBN) cutting segments were produced using hot pressing technique for this study to be used in cutting natural stone. cBN grains were added to bronze powder, the chosen matrix, at a rate of 0%, 20%, 40%, 60%, 80%, and 100% (according to percentage by weight). Segments were produced under a pressure of 35 MPa, at a sintering temperature of 600• C, over a sintering time of 3 minutes. The cutting properties of the produced segments were determined by cutting Ankara andesite. A Scanning Electron Microscope (SEM) and an X-Ray Diffractometer (XRD) were used to analyse the microstructure, phase compound, and wear surfaces of each segment type.Keywords: cBN cutting tools, hot-pressing technique, wear Diamentowe i wytworzone z regularnego azotku boru (cBN) techniką prasowania na gorąco segmenty tnące zostały zastosowane do cięcia kamienia naturalnego. Ziarna cBN dodano do proszku brązu (matrycy) w ilości 0%, 20%, 40%, 60%, 80% i 100% (wagowo). Segmenty wytworzono pod ciśnieniem 35 MPa, w temperaturze spiekania 600• C, w czasie 3 minut. Włościwości tnące wytworzonych segmentów zostały określone przez cięcie andezytu. Skaningowej mikroskopii elektronowej (SEM) i dyfrakcji rentgenowskiej (XRD) użyto do analizy mikrostruktury, składu fazowego, oraz zużycia powierzchni każdego typu segmentu.

Characterization of Functionally Graded Bronze Matrix Ceramic Reinforced Composite Materials

“…In the bronze matrix, α-Cu and Cu3Sn phases were formed as seen from XRD graphs. These phases were also identified in the literature on bronze [24]. In addition, carbide phases are clearly seen in XRD graphs.…”
