Abstract

UN TREPAN CAROTTIER DIAMANTE COMPREND UN CORPS ANNULAIRE A L'EXTREMITE DUQUEL EST FIXEE UNE COURONNE PRESENTANT UNE FACE DE COUPE. CETTE COURONNE 6 EST COMPOSEE DE SEGMENTS COMPOSITES RADIAUX 18 SEPARES PAR DE LA MATIERE D'ENTRETOISEMENT 24, LE TOUT ABOUTISSANT A LA FACE DE COUPE 10 POUR S'USER AVEC ELLE. CHAQUE SEGMENT COMPOSITE 18 EST CONSTITUE D'UNE SUCCESSION RADIALE DE SEGMENTS IMPREGNES DE DIAMANTS 20 ALTERNANT AVEC DE LA MATIERE D'ESPACEMENT 22. CES DERNIERS SEGMENTS 20 ONT UNE PLUS GRANDE RESISTANCE A L'ABRASION QUE LA MATIERE D'ESPACEMENT 22 ENTRE EUX, LAQUELLE A ELLE-MEME UNE PLUS GRANDE RESISTANCE A L'ABRASION QUE LA MATIERE D'ENTRETOISEMENT 24. APPLICATION AU MATERIEL DE FORAGE.A DIAMOND CORE TREPAN INCLUDES AN ANNULAR BODY AT THE END OF WHICH A CROWN WITH A CUT FACE IS FIXED. THIS CROWN 6 IS COMPOSED OF RADIAL COMPOSITE SEGMENTS 18 SEPARATED BY THE SPACING MATERIAL 24, THE ENTIRE ENDING AT THE CUT FACE 10 TO BE USED WITH IT. EACH COMPOSITE SEGMENT 18 IS CONSTITUTED OF A RADIAL SUCCESSION OF DIAMOND-IMPREGNATED SEGMENTS 20 ALTERNATE WITH SPACING MATERIAL 22. THESE LATEST SEGMENTS 20 HAVE GREATER RESISTANCE TO ABRASION THAN SPACING MATERIAL 22 BETWEEN THEM, WHICH HAS ITSELF GREATER RESISTANCE TO ABRASION THAN THE GROUT MATERIAL 24.
