Method for cutting thick glass
Mechanical cutting glass:Mechanical cutting glass is the mechanical property of glass with low tensile stress. The diamond or emery is used to cut the surface, and the force is cut off because of tension.(1) when glass cutters do not cut very thick glass, they use diamond glass cutters inlaid with diamond at the ends of brass and cut ordinary flat glass, and often use super hard knife wheels. In addition, when cutting, adding kerosene and other liquids, the incision and tool life are better protection. In addition, to lead the soft glass tube, but also useful to cut the file.(2) diamond saw cutting diamond saw is not limited to glass, but also widely used in the cutting of germanium, silicon, ceramics, crystal and so on. Compared with common grit or ordinary abrasive saw, diamond saw has high cutting efficiency. Generally, grinding fluid is used during cutting. The bonding materials of diamond saw include metal, thermosetting resin, ceramic and so on. But the metal saw such as brass is usually cut. The thickness of saw blade is about 0.2 ~ 7ram. Cutting method is divided into outer circle cutting, inner circle cutting and band saw cutting.
Some glass processing before processing, to the original piece of glass polishing, cutting, edge grinding, drilling, washing and drying process, such as tempered glass, laminated glass etc.; there are some glass processing technology, processing after washing and drying, and then according to the use requirements of cutting, grinding, grinding and polishing drilling and washing as final products, such as glass mirror; in addition to the art glass, such as painting, printmaking, relief, need specific processing technology, these are for cold working glass. The cold processing of glass is to process glass products into the required process by means of a series of processing methods at normal temperature.
Cutting glass with abrasivesThe original A. plus sand saw diameter 95300 ~ 400mm, 1 ~ 2ram thick brass, iron plate made of circular plate, rotated, injection abrasive (silicon carbide, corundum, corundum and so on) and the slurry water mixed, with some of the side of the glass to the saw cutting force.B. with ordinary abrasive cutting compared with ordinary wheel, diamond grinding wheel, it is difficult to cut thin products, cutting losses, grinding wheel wear, wheel but cheap, especially in dry cutting, it is common to the advantages of grinding wheel cutting.C. wire cutting with multiple jointless wire (wire or piano wire = O.05 ~ 0.2mm), can also cut about 100 sheets. The edge of the abrasive material is added to the workpiece with a certain amount of pressure, and the edge is milled and cut. Because of the grinding surface cutting, the margin is very small, you can get high-precision cutting.D. abrasive jet machining method and principle of the same blast form, but the use of abrasive powder (average particle diameter of 27 m, with a tiny belly) jet nozzle (spraying gas as carbon dioxide, nitrogen and compressed air), shot edge pores, edge cut glass plate. The impact of the abrasive is so small that it will not damage the glass. This method can process thin glass plates.
