In home decoration, when we choose the decoration of kitchen, walls will often choose some pretty patterns, such as the bathroom window we will select some patterns of conditioning, so it seems like the owner is more romantic, elegant, let people pleasing. The guests can enjoy the gentle temperament of the owner, and therefore the first choice of many people. Among them our waterjet a credit. These beautiful glass art is how to cut it? Let us see.
Glass cutting provides many new applications for water jet system, and enables the creation of sculptures and works of art into a new world. Although over the years it has been applied to gas blast texturing process water jet cutting of some details of etching and glass, but because of work pressure of gas is generally about 0.5MPa, therefore operating speed is too slow, for certain industrial applications little significance. And the application of abrasive water jet machining, its jets have the ability to cut off all material encountered, it is particularly suitable for cutting composite materials, one of which is laminated glass.
In the glass cutting, the need to pay attention to the brittleness of the glass, the workpiece must be carefully supported, in order to avoid uneven support surface of the bending stress generated in the glass, the role of the cutting point is similar to a stress concentration point. When before cutting the glass the start of the perforation, because of stop the jet, it may lead to the generation and propagation of cracks. However, such a composite material after cutting along the contour line does not affect the properties of the material, especially in cutting thicker material the advantage is more prominent. The processing of the traditional processing methods for the safety glass which a layer of plastic between two layers of glass is first cut with a diamond grinding wheel to carve grooves on the surface, and then use the impact to cut, the consumption of interlayer material is 30%, and cut with abrasive water jet through three layers of different materials with no deviation, this issue is resolved immediately. Therefore it is suggested that under the condition that the potential penetration, the jet pressure should be 70 ~ 80MPa, until the perforation is completed the jet pressure should not be raised to the actual cutting pressure. In this way, the crack caused by the pressure will not cause the whole plate of the scrap, but produce localized surface debris, through reasonable arrangement of cutting path can avoid the impact on the performance and appearance of the finished product.
In addition, for certain special purposes after the heat treatment of prestressed glass material need special treatment. Due to the influence of prestress, the end of any crack will produce a large enough stress concentration, such materials typically will smash due to cracks, so based on this reason is not recommended to use water jet cutting similar materials. When the jet completely divergent in the slit edge will have undesirable burrs, when cutting the workpiece spatter grains may scratch the workpiece and cause a threat to the operator, which must be observed and prevention.
Glass products are the most common in our lives, waterjet is one of the "behind the scenes operatives", it brings us beautiful experience and spiritual perception. Waterjet brought us beautiful art to enjoy.
