Definitions
- the invention relates to a grinding wheel for a grinding wheel for grinding optical glasses, precious stones, marble or the like.
- the invention relates to grinding wheels in the form of pellets for a grinding wheel for grinding glasses. Therefore, it is hereinafter predominantly spoken of spectacle lenses, without this being a limitation for the 1 Einsat 'z of the grinding body connectedness that is'.
- the grinding plate has a curvature on the side facing the spectacle lens which corresponds to the curvature of the glass to be produced.
- a large number of grinding wheels, the so-called pellets, are 'glued' to the surface of the plate.
- These grinding tools usually consist of a sintered diamond powder-metal mixture.
- Heavy metals such as bronze and bronze alloys are used as the metal.
- the abrasives wear and it is created as a grinding back and a mixture of glass dust, heavy metal powder and diamond powder. It is evident that the disposal of such a residue, particularly because of the heavy metal, is problematic.
- the invention is based 'on the object, form an abrasive article to the purposes described above so that the problem of Ent'sorgung is avoided.
- the abrasive body has a base body made of a sintered hard material * , on which a diamond coating is 'arranged' as an abrasive layer.
- This has the advantage that only diamond powder and dust from the material of the object to be ground, e.g. B. glass dust, 1 is created, which can be disposed of in an environmentally friendly manner 1 . A recycling of the glass dust together with the diamond powder is easily possible.
- Carbides, nit'rides, carbonit'rides and / or silicides can be used as hard materials for the base body.
- the base body can also consist of a sintered ceramic, which has the advantage that the abrasion of the base body can be disposed of without problems.
- the base body can also contain silicon nitride Si ⁇ N, and / or its compound. This fabric is very hard and resistant.
- the base body can of course also consist of a sintered hard metal. It can be useful here be if the base body contains tungsten carbide or tungsten carbide and cobalt. Tungsten carbide is also very hard and resistant and is used in industry as a base metal for tough, hard components.
- the base body can be made of hard carbon and / or graphite, particularly inexpensive materials with a low expansion coefficient.
- the diamond coating is preferably applied to the base body by gas phase deposition.
- a very thin and homogeneous layer can be produced using this method, also known as CVD (Chemical Vapor Deposition).
- CVD Chemical Vapor Deposition
- the coating has a thickness of 5 to 50 ⁇ m.
- a preferably electroplated intermediate layer of precious metal for example of gold, silver, platinum or iridium, can be provided between the base body and the diamond coating.
- the shape of the grinding body is basically arbitrary and essentially depends on the grinding plate and the workpiece to be machined.
- the grinding wheel for processing gemstones or marble can be a ring and a pellet for a grinding plate for grinding spectacle lenses.
- Such a pellet can have a thickness of 3 to 6 mm and a diameter of 5 to 15 mm.
- the pellets can also be polygonal, e.g. B. be substantially rectangular.
- the base body of the grinding bodies can be produced by known sintering processes. At least one surface of the finished sintered body is then provided, for example in the CVD process, with a thin diamond layer, a layer of noble metal as an adhesion promoter and for voltage equalization being galvanically applied to the surface of the base body which is to carry the diamond layer, before the diamond layer is applied Base body and diamond layer can be applied.
- the coated abrasive bodies are attached in the usual way on the grinding plate, e.g. B. glued.
- the grinding plate itself can form the base body of the grinding body and can be made from materials suitable for the base body. In order to apply a diamond coating corresponding to the individual abrasive bodies to such a large-area base body, it is sufficient to cover the areas of the base body which are not to be coated during the CVD process.
- the thin diamond coating wears out, so that the base body is exposed. After that, the workpiece can no longer be ground, which also shows the wear of the grinding body. The grinding wheels must then be replaced. It can also be provided that the used base bodies are coated repeatedly. Waste products in an amount as they are obtained according to the prior art are therefore avoided.
- FIG. 5 is a plan view of the grinding plate according to FIG. 4.
- the grinding plate 11 shown in FIG. 1 has a curved surface 12. On this surface 12 there are a large number of grinding wheels 13, the so-called pel lets, arranged. The grinding wheels 13 lie close together and thereby form a grinding surface 14 on which the spectacle lens (not shown) lies during processing.
- the grinding plate 11 has on its side facing away from the surface 12 a coupling 15, via which the grinding plate is connected to the grinding device.
- the other assemblies of the grinding device are not shown for the sake of clarity.
- a pellet 13 has a base body 16 made of sintered ceramic, the surface 17 of which faces away from the grinding plate 11 is provided with a thin diamond coating 18. Between the surface 17 and the diamond coating 18, a noble metal intermediate layer 19 is also provided as an adhesion promoter. This diamond coating 18 or the sum of the individual layers on the base bodies 16 forms the grinding surface 14. The diamond coating 18 wears out during the grinding process while the base body 16 no further wear and tear. It is thus possible to coat the base body 16 again after the diamond coating 18 has worn out.
- the base body 16 is a sintered part made of a hard material, the surface of which often has a certain roughness.
- the grinding process can be supported by the roughness.
- the diamond coating 18 is preferably applied to the base body 16 by gas phase deposition, which ensures that at least the surface 17 of the base body is completely provided with the diamond coating 18 even if the roughness is present.
- only the surface 17 of the base body 16 is provided with a diamond coating 18. It goes without saying that, depending on the type of gas phase deposition, other surfaces of the base body can also be provided with the diamond coating.
- annular base body 32 made of graphite is attached to the edge of a metal plate 35 held on a rotatable spindle 31.
- the surface of the base body 32 which points away from the metal plate 35 bears an electrodeposited intermediate metal layer 33, on which a diamond coating 34 is applied as an abrasive coating by the CVD method.
- the area of the metal plate 35 between the annular base body 32 and the spindle 31 is further provided with a diamond impregnation 36.
- the grinding 'eller 41 in FIGS. 4 and 5 shown at the same time forms the group consisting of hard carbon body 42 of a grinding wheel and has a coupling 43 for connection to a non-illustrated abrasive device.
- island-shaped zones On the surface of the grinding plate 41 opposite the coupling 43, island-shaped zones have been provided with a diamond coating 44 as a grinding surface by the CVD method by covering the areas 45 of the grinding plate 41 that are not to be coated during the coating process.
- the invention is not limited to the illustrated and described embodiments. It includes modifications familiar to those skilled in the art.
- a plurality of annular grinding bodies, between which diamond impregnations are provided, can be arranged on a grinding wheel.
- the edge area of the grinding wheel can also have diamond impregnation, which is adjoined by annular grinding bodies towards the center of the wheel.
- the ring-shaped grinding bodies can also be held on the edge of cup-shaped grinding plates or grinding wheels, wherein the surface of the grinding bodies carrying the diamond coating can be curved.
