[China Glass Net] Glass is easily broken during the engraving process. Therefore, glass engraving must be very careful. For different types of glass, the amount of lead is different, and the engraving method is not the same. As the lead content increases, the hardness and high temperature viscosity of the glass decrease, and the glass is more likely to be broken. Ordinary glass is usually easier to engrave than crystal glass because of its high lead content and reduced hardness and viscosity, which increases the difficulty of laser engraving. Glass laser engraving process: When the laser beam touches the surface of the glass, the surface of the glass is heated and the glass molecules are scattered. If the glass can't be cooled down, the pits that are heated will become bigger and bigger, and the engraving effect will be as bad as the mud. Two glass laser engraving techniques are recommended below to solve the above problem of glass melting: 1. Before the glass is carved, first wet the glass surface. You can cover the glass with a wet newspaper, or you can wet the glass with a cleaning solution, so that the glass engraving effect will be better. However, it should be noted that the water on the surface of the glass will quickly dry out. 2, after our proofing test, before the glass engraving, use the protective foil or tape to cover the surface of the glass, so that the engraving effect is better. If the workpiece needs to be sandblasted, the laser engraving machine can quickly make a suitable engraving template: apply the protective coating directly to the glass, and then use a laser engraving machine to trace the pattern. If you are working with hemispherical glass, you must choose a longer focusing wavelength, such as a 2.5-inch focusing wavelength. Because the longer the focusing wavelength, the larger the working area. Then focus the focus point in the center position so that the outer edge of the focus point can get a good engraving effect.
