Description
<Desc/Clms Page number 1>
Procédé de fabrication d'outils à meuler contenant du diamant et outils à meuler fabriqués d'après ce procédé,
Les minéraux durs: saphir, rubis, grenat, agate, etc., sont de préférence taillés avec le diamant parce que
<Desc/Clms Page number 2>
celui-ci possède une dureté plus grande que celle de ces pierres. On connaît également un certain nombre d'alliages de métaux durs qui, par suite de leur dureté élevée, ne peuvent être travailles que péniblement et avec de grandes pertes de temps et d'argent avec les meules connues en carborundum. Pour cette raison on cherche de plus en plus à créer de nouveaux outils abrasifs capables de fournir, non seulement un travail fin, mais en outre un dégrossissage efficace et meulage rapide, de ne pas s'encrasser et de ne pas exiger des appareils spéciaux et compliqués.
On a réussi à créer un procédé d'après lequel on peut fabriquer des meules et d'autres outils abrasifs avec du diamant en y mélangeant du saphir pulvérisé (corindon) du carborundum, des boro-carbures et d'autres grains de matière abrasive et en les liant avec des matières céramiques, sans que le diamant soit brûlé par la grande chaleur nécessaire dans ce cas. Ces meules permettent de dégrossir en un temps étonnament court les pierres les plus dures, les métaux et d'autres matériaux durs, ou de les polir finement et à arête vive suivant le choix du grain, l'outil ne s'usant que très peu par rapport à sa grande puissance.
Avantageusement, on mélange des grains ou de la poudre de diamant, passant par les tamis 100 à 400, ou bien de la poussière de diamant d'une extrême finesse, avec un ou plusieurs matériaux durs, par exemple du
<Desc/Clms Page number 3>
saphir synthétique ou naturel, du rubis ou d'autres pierres fines à base d'oxyde d'alumine, du carbure de silicium, de l'émeri etc. en y ajoutant de l'alumine et des silicates; on moule, on presse et on lie céramique- ment par cuisson. La composition des outils à meuler est différente suivant les applications qui, on le sait, sont très variables.
On peut par exemple mélanger 7 parties de poudre de diamant pure, 5 parties de saphir synthéti- que, 1 partie d'alun calciné, 2-3 parties d'alumine (suivant la dureté désirée), 3 parties de glycérine, 4 parties d'eau de colle, on moule et on effectue la cuisson à haute température. La température de cuisson peut fortement varier suivant qu'on désire fabriquer des outils durs ou plus ou moins tendres. De même, les dosages dans la formule qui précède doivent être choisis d'après le genre d'application des outils.
Comme liants, on peut se servir de silice, de quartz, de silicates, par exemple du feldspath, de verre soluble, d'oxydes métalliques ou de poudre de verre, seuls ou avec de l'alumine. Les corps de meules ainsi soumis b la cuisson peuvent pratiquement être adaptés aux opérations d'usinage dans leur forme d'ori- gine ou montés sur des mandrins métalliques ou encore fixés sur des supports de formes variables.
Pour le cas, où le liant céramique ne suffit pas, il est également possible de lier la poudre de diamant et le minéral dur-par exemple la poudre de saphir- à
<Desc/Clms Page number 4>
l'aide d'un métal, tel que l'antimoine, l'étain, le zinc, le cuivre, etc., en mélangeant la poudre de diamant avec au moins un minéral dur et au moins un métal, en faisant se concréter ou fondre le mélange, le métal servant alors de liant.
Revendications s
1. Procédé de fabrication d'outils en diamant, caractérisé en ce qu'on mélange la poudre de diamant avec au moins un minéral dur et au moins un liant céramique, on moule et on réunit les constituants par cuisson.
2. irocédé suivant la revendicationl, caractérisé en ce que le liant peut être constitué par de l'alumine, un silicate, de la silice, du quartz, du feldspath, un oxyde métallique, du verre soluble, de la poudre de verre, etc.
3. Procédé suivant la revendicationl,caractérisé en ce qu'on employe simultanément au moins deux liants.

Process for manufacturing grinding tools containing diamond and grinding tools manufactured according to this process,
Hard minerals: sapphire, ruby, garnet, agate, etc., are preferably cut with diamond because
<Desc / Clms Page number 2>
this one has a hardness greater than that of these stones. A number of hard metal alloys are also known which, owing to their high hardness, can only be worked with great difficulty and with great loss of time and money with the known grinding wheels in carborundum. For this reason, more and more attention is being paid to creating new abrasive tools capable of providing not only fine work, but also efficient roughing and rapid grinding, not clogging and not requiring special devices and complicated.
A process has been created whereby grinding wheels and other abrasive tools can be made with diamond by mixing powdered sapphire (corundum), carborundum, boro-carbides and other grains of abrasive material and by binding them with ceramic materials, without the diamond being burnt by the great heat necessary in this case. These grinding wheels allow the hardest stones, metals and other hard materials to be roughened in a surprisingly short time, or to polish them finely and with a sharp edge depending on the choice of the grain, the tool wearing very little compared to its great power.
Advantageously, diamond grains or powder, passing through sieves 100 to 400, or extremely fine diamond dust, are mixed with one or more hard materials, for example
<Desc / Clms Page number 3>
synthetic or natural sapphire, ruby or other fine stones based on alumina oxide, silicon carbide, emery etc. by adding alumina and silicates; it is molded, pressed and ceramic bonded by firing. The composition of the tools to be grinded is different according to the applications which, as we know, are very variable.
For example, 7 parts of pure diamond powder, 5 parts of synthetic sapphire, 1 part of calcined alum, 2-3 parts of alumina (depending on the desired hardness), 3 parts of glycerin, 4 parts of alumina can be mixed. glue water, molded and baked at high temperature. The firing temperature can vary greatly depending on whether it is desired to manufacture hard or more or less soft tools. Likewise, the dosages in the above formula should be chosen according to the kind of application of the tools.
As binders, silica, quartz, silicates, for example feldspar, water glass, metal oxides or glass powder, alone or with alumina can be used. The grinding wheel bodies thus subjected to firing can in practice be adapted to machining operations in their original shape or mounted on metal mandrels or else fixed on supports of varying shapes.
For the case, where the ceramic binder is not enough, it is also possible to bond the diamond powder and the hard mineral - for example sapphire powder - to
<Desc / Clms Page number 4>
using a metal, such as antimony, tin, zinc, copper, etc., by mixing the diamond powder with at least one hard mineral and at least one metal, causing it to solidify or melt the mixture, the metal then serving as a binder.
Claims s
1. Process for manufacturing diamond tools, characterized in that the diamond powder is mixed with at least one hard mineral and at least one ceramic binder, the components are molded and joined by firing.
2. irocédé according to claiml, characterized in that the binder can be constituted by alumina, a silicate, silica, quartz, feldspar, a metal oxide, soluble glass, glass powder, etc. .
3. Method according to claiml, characterized in that simultaneously employs at least two binders.
