Definitions
- This segment thus performs the removal function of the coating, given the ability of the cutting edge to peel it, and this, stably, via a self-sharpening mechanism hard edge in contact with the mineral substrate, and the substrate polishing function by adapting judiciously the characteristics of the support layer to a grinding job.
- the wear is therefore concentrated there and, quickly essential peeling function is no longer ensured.
- the segments consist of two layers, one first hard and thin first layer 3 generally consisting of metallic binder enclosing fine diamond grains, the order of 0.2 mm in diameter circumscribed in strong concentration, of the order of C60 in FEPA concentration, and a second layer 4 generally consisting of a binder metallic enclosing larger diamond grains ( even conventional abrasive), of the order of 0.6 mm diameter circumscribed in lower concentration, of the order of C40 in FEPA concentration.

Abstract
Description
- La fig. 1 est une vue en perspective d'un segment abrasif de la meule de l'invention,
- La fig. 2 est une vue en plan du segment de la Fig. 1,
- La fig. 3 est une coupe de ce segment,
- La fig. 4 est une vue en perspective d'une meule de l'invention,
- Les fig. 5 et 6 sont des coupes selon un axe passant par deux types de segments de la meule de la fig. 4,
- La fig. 7 est une vue schématique, en plan, de deux segments successifs de la même meule.
Claims (9)
- Meule de surfaçage en forme de cuvette constituée d'un corps (10) percé de trous (11) garni de segments en forme de soc de charrue présentant 2 flancs inégaux (1) et (2) par rapport à la direction en rotation caractérisé en ce que les segments sont disposés selon au moins deux dispositions différentes (8) et (9) de façon à présenter , en cours du processus de coupe, l'arête de coupe selon au moins quatre inclinaisons différentes.
- Meule selon la revendication 1 caractérisée par en ce que les segments présentent une face de coupe inclinée d'un angle (5) par rapport à son plan de base (6) qui permettent de ménager une coupe positive dans le sens de la coupe en rotation dans la matière à travailler.
- Meule selon l'une quelconque des revendications 1 et 2 caractérisée en ce que les segments placé selon au moins une des dispositions (9) présentent une face de coupe (3) inclinée d'un angle (5) par rapport à son plan de base (6) qui permettent de ménager une coupe positive dans le sens de la coupe en avalant dans la matière à travailler.
- Meule selon l'une quelconque des revendications précédentes caractérisée en ce que les segments sont constitués de deux couches, la première dure et fine (3) constituée en substance d'un liant métallique enserrant des grains d'abrasif fins, la deuxième(4) constituée en substance d'un liant métallique enserrant des grains d'abrasif plus gros que ceux de la première couche.
- Meule suivant la revendication 4 caractérisée en ce que les grains d'abrasif sont constitués de diamant.
- Meule selon l'une quelconque des revendications 4 et 5 caractérisée en ce que la première couche a des grains de l'ordre de 0.2 mm de diamètre circonscrit en forte concentration, de l'ordre de C60 en concentration FEPA.
- Meule selon l'une quelconque des revendications 4, 5 et 6 caractérisée en ce que la deuxième couche est constituée de grains d'abrasif de l'ordre de 0.6 mm de diamètre circonscrit en plus faible concentration, de l'ordre de C40 en concentration FEPA.
- Meule selon l'une quelconque des revendications précédentes caractérisée en ce qu'une partie des segments (8) est disposée avec l'axe du profil tangent au cercle passant par la pointe du profil.
- Meule selon l'une quelconque des revendications précédentes caractérisée en ce qu'une autre partie des segments (9) est disposée avec le flanc court tangent au cercle extérieur correspondant à la périphérie de l'outil.
