corps de révolution.body of revolution.
Dans les meules'connues de ce genre, telles que les meules dites superabrasives, le bandeau imprégné de particules abrasives est collé ou brasé de façon définitive In known grinding wheels of this kind, such as so-called superabrasive grinding wheels, the strip impregnated with abrasive particles is permanently bonded or brazed

Afin de remédier au caractère peu économique que présente la mise en oeuvre de telles meules, l'invention a pour objet une meule dont le support se compose de deux éléments; ceux-ci peuvent être juxtaposés sur un même axe de révolution et leurs bords circulaires sont façonnés pour pouvoir recevoir et, après serrage mutuel desdits éléments juxtaposés, assujettir par pincement en situation centrée sur ledit axe le bandeau abrasif, réalisé sous In order to remedy the uneconomical nature of the implementation of such grinding wheels, the invention relates to a grinding wheel whose support consists of two elements; these can be juxtaposed on the same axis of revolution and their circular edges are shaped to be able to receive and, after mutual tightening of said juxtaposed elements, subjecting the abrasive strip, produced under pinching in a situation centered on said axis

Ainsi, la meule selon l'invention comporte un bandeau abrasif non pas fixé définitivement à son support, mais amovible et tenu par simple serrage entre les deux éléments du support Il peut donc être remplacé après Thus, the grinding wheel according to the invention comprises an abrasive strip not permanently fixed to its support, but removable and held by simple clamping between the two elements of the support. It can therefore be replaced after

La structure particulière d'une telle meule-boisseau peut être mise à profit pour assurer l'application d'un liquide de coupe sur le bandeau abrasif Dans ce but, la surface de pincement qu'offre le rebord périphérique de l'élément intérieur est creusée de rainures sensiblement radiales qui permettent au liquide de coupe, introduit via la broche d'entraînement creuse sur laquelle est montée la meule et des orifices percés dans cette broche au niveau de l'espace intermédiaire séparant les deux éléments du supportd'atteindre, en passant par cet espace o il est amené à la vitesse de meulage, la partie active du bandeau abrasif. Une meule selon l'invention peut aussi présenter la conformation dtune meule cylindrique; les éléments du The particular structure of such a cup wheel can be used to ensure the application of a cutting liquid on the abrasive strip. For this purpose, the pinching surface offered by the peripheral edge of the interior element is hollowed out of substantially radial grooves which allow the cutting liquid, introduced via the hollow drive spindle on which the grinding wheel is mounted and holes drilled in this spindle at the intermediate space separating the two elements of the support to reach, passing through this space where it is brought to the grinding speed, the active part of the abrasive strip. A grinding wheel according to the invention can also have the conformation of a cylindrical grinding wheel; the elements of

tutives distinctes: un élément extérieur 1, un élément intérieur 2 et un bandeau 3 comportant une partie abrasive 3 a Les éléments 1 et 2, réalisés en bakélite, en métal ou en compound bakélite-aluminium, présentent la forme d'une cuvette à fond plat percé d'un trou central respectif 4,5 qui permette le montage sur une broche 6 d'entraînement en rotation Le bandeau 3, monobloc comme les éléments 1 et 2, comporte un rebord interne 3 b faisant apparaître deux distinct trutives: an external element 1, an internal element 2 and a strip 3 comprising an abrasive part 3 a The elements 1 and 2, made of bakelite, metal or a bakelite-aluminum compound, have the shape of a bottom bowl flat pierced with a respective central hole 4.5 which allows mounting on a spindle 6 for driving in rotation The strip 3, monobloc like the elements 1 and 2, has an internal rim 3 b showing two
surfaces annulaires 7,8 contenues dans des plans perpen- annular surfaces 7.8 contained in perpetual planes
diculaires à l'axe de révolution 9 de la meule 10 et de ses parties constitutives 1,2 et 3 Ce rebord permet la fixation du bandeau 3 aux éléments 1 et 2 qui constituent dicular to the axis of revolution 9 of the grinding wheel 10 and its constituent parts 1, 2 and 3 This rim allows the fixing of the strip 3 to the elements 1 and 2 which constitute

Lorsque la partie abrasive 3 a du bandeau 3 est usée, il suffit de procéder à l'échange de celui-ci contre un bandeau neuf, les éléments supports 1 et 2, non soumis à usure, restant toujours réutilisables On desserre l'écrou 14 et on déboîte les éléments 1 et 2, cc; qui libère le bandeau usé que l'on ôte et auquel on substitue le bandeau neuf On peut de même échanger le bandeau 3, encore utilisable, contre un autre bandeau de propriétés abrasives différentes, en conservant toujours les éléments 1 et 2. La figure 1 montre que la broche d'entraînement 6 When the abrasive part 3 a of the strip 3 is worn, it suffices to exchange the latter for a new strip, the support elements 1 and 2, not subject to wear, always remaining reusable. The nut 14 is loosened and we disengage elements 1 and 2, cc; which releases the worn strip which is removed and replaced by the new strip. The strip 3, still usable, can likewise be exchanged for another strip with different abrasive properties, always keeping the elements 1 and 2. FIG. 1 shows that the drive pin 6
