DESCRIPTION
La présente invention concerne un procédé de fabrication de motifs artistiques et décoratifs sur les gemmes et les minéraux. DESCRIPTION
The present invention relates to a method of making artistic and decorative patterns on gems and minerals.
L'outil utilisé traditionnellement se compose de fraises diamantées activées par un moteur électrique et manié à la main. The tool traditionally used consists of diamond burs activated by an electric motor and operated by hand.
L'invention se base sur le principe connu de gravure à partir d'un masque en résine photo-sensible et soluble dans l'eau,dont les étapes à titre d'exemple sont les suivantes : a) création d'une image noire sur film transparent(2) par photo-copie ou imprimante laser, b) transfert de l'image du film sur une résine (3) stratifiée photo-sensible et soluble à l'eau par exposition aux rayons ultrat-violet, c) lavage de la résine stratifiée à l'eau, les parties de la résine non soumises aux rayons seront dissoutes à l'eau, le reste formant un masque,(4) d) séchage du masque par air chaud ventilé,
Le procédé selon l'invention comporte une première caractéristique,où l'application du masque en résine à l'aide d'un adhésif,en vue de la projection de corindon, s'effectue sur un gemme(5) ou un minéral(5), alors que les procédés connus sont applicables à toutes sorte de support tel que le verre, le métal, la pierre ,le cuir, mais ne s'applique pas à des gemmes ou des minéraux. The invention is based on the known principle of etching from a mask made of photosensitive resin and soluble in water, the steps of which, by way of example, are as follows: a) creation of a black image on transparent film (2) by photo-copying or laser printer, b) transfer of the film image onto a photo-sensitive and water-soluble laminated resin (3) by exposure to ultra-violet rays, c) washing of the resin layered with water, the parts of the resin not subjected to the rays will be dissolved in water, the rest forming a mask, (4) d) drying of the mask by hot ventilated air,
The method according to the invention comprises a first characteristic, where the application of the resin mask with the aid of an adhesive, with a view to the projection of corundum, is carried out on a gem (5) or a mineral (5). ), while the known processes are applicable to all kinds of support such as glass, metal, stone, leather, but do not apply to gems or minerals.
Le procédé selon l'invention comporte une deuxième caractéristique, où la gravure du gemme ou du minéral se fait par projection de corindon contenant 99,80% en AL203, ayant un point de fusion de 2050 degrés celsius environ,et une dureté KNOOP de 2100 KG/mm2 (hklOO), et une granulométrie de u63 ou de u75, ce qui exclut la gravure de gemme comme le rubis,le saphir, le diamant qui ont une dureté supérieure ou égale à 9 sur l'echelle de MOSH. The method according to the invention comprises a second characteristic, where the engraving of the gem or mineral is carried out by spraying corundum containing 99.80% in AL203, having a melting point of approximately 2050 degrees celsius, and a KNOOP hardness of 2100 KG / mm2 (hklOO), and a particle size of u63 or u75, which excludes the engraving of gemstones such as ruby, sapphire, diamond which have a hardness greater than or equal to 9 on the MOSH scale.
Selon des modes de projection de corindon ,le diamètre des buses peut aller de 4 mm à 6 mm et la pression de l'air pulsé peut être comprise entre 4 kg/cm2 et 7 kg/cm2, le débit de l'air requis est compris entre 260 1/mn ou
3001/mn. According to corundum projection modes, the diameter of the nozzles can range from 4 mm to 6 mm and the pressure of the pulsed air can be between 4 kg / cm2 and 7 kg / cm2, the required air flow rate is between 260 1 / min or
3001 / min.
) Les dessins anexés illustrent l'invention : la fig.l représente le gemme ou le minéral à graver. la fig. 2 représente le film transparent avec l'image noire à transférer sur la résine photo-sensible dont l'exposition aux rayons n'est pas illustré. ) The appended drawings illustrate the invention: fig.l represents the gem or mineral to be engraved. fig. 2 shows the transparent film with the black image to be transferred to the photosensitive resin whose exposure to the rays is not illustrated.
5 La fig. 3 représente la résine photo-sensible avant exposition aux rayons. 5 Fig. 3 represents the photosensitive resin before exposure to the rays.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
La fig. 4 représente la résine photo-sensible après exposition aux rayons ,qui après lavage et séchage donne le masque à graver. Fig. 4 represents the photosensitive resin after exposure to the rays, which after washing and drying gives the mask to be engraved.
La fig. 5 représente une première caractéristique de l'invention qui est l'application du masque de la fig.4 sur le gemme ou le minéral par un adhésif, l'ensemble ainsi constitué subit une projection de corindon dont les caractéristiques techniques sont expliqués plus haut mais non illustrés. Fig. 5 represents a first characteristic of the invention which is the application of the mask of FIG. 4 on the gem or mineral by an adhesive, the assembly thus formed is subjected to a projection of corundum, the technical characteristics of which are explained above but not shown.
La fig. 6 représente le gemme ou le minéral gravé selon l'image de la fig.l,en petits hachurés. Fig. 6 represents the gem or mineral engraved according to the image of fig.l, in small hatched lines.
Le procédé selon l'invention est destiné pour la fabrication de camées ou de médailles ou de cabauchons, gravés, dans le domaine de la bijouterie. The method according to the invention is intended for the manufacture of cameos or medals or cabauchons, engraved, in the field of jewelry.
