Abstract
En skrapeborkrone (10) med et fasettert profil og fremgangsmåte for dens fremstilling hvor fasettene gir plane støpeformflater hvorpå kjerner med plane ender kan fullstendig kontakte støpeformens overflate. Oppfinnelsen er særlig, skjønt ikke utelukkende, tilpasset matrise-skrapeborkronelegemet som innehar PDC-skJær (18) med volframkarbid-tapper eller sylindere som er montert i vinger, ribber eller blader (16) på borkronelegemet (12). I samsvar med en foretrukket utførelse av den foreliggende oppfinnelse har vingene, ribbene eller bladene (16) en liten, plan overflate eller fasett (22) ved hvert sted for PDC-skJærene (18) hvor hver av fasettene (22) er ved en bestemt vinkel-plassering med hensyn til aksen for den tilsvarende skjærtapp. Fasettene (22) skapes av flate støpeform-flater som muliggjør korrekt posisjonering og vinkel-plassering av kjernene som danner åpninger i matrisen for opptak av PDC-skJærene (18). Ved utøvelse av den foreliggende oppfinnelse dannes fasettene (22) eller flatene i en hard støpeform under maskinering, eller i en bløt støpeform ved å benytte et borkronemønster som har korresponderende fasetter.
