The glass is a material difficult to be processed independently. Without appropriate tool, it may be hard to cut. Mechanical methods for cutting glass may lead to the damage of the entire glass surface. As long as cutting a straight line in glass using a diamond blade is relatively easy, to cut a curve may be a real challenge. When breaking the glass previously cut with a blade, some splinters and sharp edges may occur. In extreme cases, even the whole glass surface may break. The solution to this problem may be to cut windowpanes using the water-jet cutting technology..
The water-jet cutting may be divided into two stages. The first one consists in the creation of an entry point followed by perforation of the material under low pressure to avoid damage of the windowpane. Once the glass surface is perforated, the circulating pump is switched to high pressure of water, which cuts the material without any risk of damaging the windowpane. When using the water jet technology, the cutting surface is smooth, without any splinter or chips, thanks to which it does not require any additional processing. Furthermore, the glass edge cut using water jet is also matt, thus, it may be used for gluing after cutting. The water jet technology allows to cut various, even the most fanciful shapes. A wide array of types of glass may be subject to water jet cutting. Both solid and coated glass are suitable for water jet cutting. What is more, even bulletproof, ballistic and wired glass may be cut using water jet. Both white and colored glass as well as mirrors may be cut using water jet. One of the types of glass that may not be cut is the tampered glass, in case of which a jet of water may release stresses accumulated in the hardening process, which, in turn, may lead to cracks in the windowpane at the first contact with high pressure water jet.
