Jewelry Laser Engraving Machine
Not real crystal, but artificial crystal. The Jewelry Laser Engraving Machine is the most useful tool for "internal carving" of artificial crystals (also known as "crystal glass"). Laser engraving technology is used to "carve" flat or three-dimensional patterns into the inside of crystal glass. Carving is an ancient art. Generally, the carving process starts from the outside, and the desired shape is carved from the outside of the material. However, the laser can be used to "handle the feet" like Sun Wukong. Looking closely, there are no openings around these glass and crystal products for the "carver" to enter and exit. In this regard, the principle of laser engraver is actually very simple.
For the Jewelry Laser Engraving Machine to be able to engrave glass, its energy density must be greater than a certain threshold value, or threshold, that causes the glass to break, and the energy density of the laser somewhere is related to its spot size at that point. The smaller the spot, the greater the energy density. In this way, through proper focusing, the energy density of the laser can be lower than the damage threshold of the glass before entering the glass and reaching the processing area, and exceeding the critical value in the area to be processed, the laser generates pulses in a very short time. Its energy can cause the crystal to be thermally broken in an instant, resulting in extremely small white spots, carving a predetermined shape inside the glass, while the rest of the glass or crystal remains intact and intact.
