Description :
\nLe diamant \u00e0 grain de scie SND890 est con\u00e7u avec une pr\u00e9cision m\u00e9ticuleuse gr\u00e2ce \u00e0 sa structure cristalline cubique-octa\u00e9drique. Il se caract\u00e9rise par des angles d\u2019ar\u00eate uniformes (109,5\u00b0 entre faces adjacentes) et des inclusions internes minimales. Cette conception lui conf\u00e8re une int\u00e9grit\u00e9 structurelle exceptionnelle, renforc\u00e9e par une stabilit\u00e9 thermique de pointe. Le SND890 conserve sa duret\u00e9 (< >> 90 HRC) et son efficacit\u00e9 de coupe, m\u00eame expos\u00e9 \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es et constantes allant jusqu\u2019\u00e0 1 200 \u00b0C \u2014 une caract\u00e9ristique essentielle pour les applications \u00e0 fort frottement, telles que le forage continu de roches dures ou l\u2019exploitation mini\u00e8re en profondeur. <\/p>\n
Con\u00e7u pour les outils diamant\u00e9s professionnels, le SND890 am\u00e9liore consid\u00e9rablement les performances des lames, des forets et des fils diamant\u00e9s en r\u00e9duisant la d\u00e9gradation thermique lors d’une utilisation prolong\u00e9e. Il en r\u00e9sulte une dur\u00e9e de vie des outils accrue de 30 \u00e0 40 % par rapport aux grades standards, une r\u00e9duction des interventions pour remplacement et des taux d’enl\u00e8vement de mati\u00e8re constants, jusqu’\u00e0 20 % sup\u00e9rieurs aux alternatives de milieu de gamme, lors de la d\u00e9coupe de mat\u00e9riaux durs comme le granit, le basalte et le b\u00e9ton arm\u00e9. <\/p>\n
Tailles de grains disponibles : 20\/25, 25\/30, 30\/35, 35\/40, 40\/45, 45\/50 mesh (plage de taille des particules : 0,425 mm \u2013 1,00 mm), avec un contr\u00f4le de tol\u00e9rance strict (\u00b15 % de la taille nominale) pour un collage uniforme de l’outil et des performances pr\u00e9visibles.<\/p>\n

\nA: Le SND890 est un choix de premier ordre pour les industries exigeantes qui requi\u00e8rent des performances constantes dans des conditions extr\u00eames, notamment l’exploitation mini\u00e8re en profondeur (pour l’extraction de minerai), les grands chantiers de construction (comme le creusement de tunnels et le forage de fondations) et l’exploration g\u00e9ologique (\u00e9chantillonnage de roches dures). Sa stabilit\u00e9 thermique le rend \u00e9galement tr\u00e8s pr\u00e9cieux dans des secteurs sp\u00e9cialis\u00e9s comme le traitement des mat\u00e9riaux r\u00e9fractaires. <\/li>\n
\nR : Oui, le SND890 est particuli\u00e8rement adapt\u00e9 au forage de formations rocheuses dures (duret\u00e9 Mohs de 7 \u00e0 9), telles que le granit, le quartzite et le gneiss. Sa combinaison d’une r\u00e9sistance \u00e0 la compression \u00e9lev\u00e9e (<> > 20 GPa), d’un faible coefficient de dilatation thermique (1,1 \u00d7 10\u207b\u2076\/\u00b0C) et d’une r\u00e9sistance aux chocs thermiques lui permet de conserver son tranchant m\u00eame lors de s\u00e9ances de forage prolong\u00e9es, r\u00e9duisant ainsi l’usure du tr\u00e9pan et les co\u00fbts d’exploitation. <\/li>\n
\nA : La forme r\u00e9guli\u00e8re cube-octa\u00e8dre du grain SND890 assure une r\u00e9partition uniforme de la charge sur toute la surface du diamant pendant la coupe, minimisant ainsi les concentrations de contraintes susceptibles d’entra\u00eener une rupture pr\u00e9matur\u00e9e. Cette structure favorise \u00e9galement une abrasion homog\u00e8ne, ce qui se traduit par des coupes plus nettes et une r\u00e9duction du gaspillage de mati\u00e8re par rapport aux grains de forme irr\u00e9guli\u00e8re. <\/li>\n
\nR : Oui, le SND890 s’int\u00e8gre parfaitement aux syst\u00e8mes de collage courants utilis\u00e9s dans la production d’outils professionnels, notamment les collages \u00e0 matrice m\u00e9tallique, \u00e0 r\u00e9sine et \u00e9lectrolytiques. Ceci garantit une forte adh\u00e9rence et des performances fiables pour divers processus de fabrication. <\/li>\n<\/ul>\n
