    1. 3D Laser Engraving Machine LE-2 --- For small volume crystal process

    2. 1. 3D laser engraving system from Lelee laser technology Co. Ltd. adopts advanced laser marking technique to sculpture symbols, photos, and two or three dimensional images inside transparent crystals, and it won't deface the surface of object. The images sculptured can remain permanent. High-energy laser beams can produce nonlinear absorption inside transparent material, and then some small dots appear after subtle bursting. Those dots are arranged to be two- or three-dimensional images under the control of computer. Making use of this principle, words, pictures or any 3D images can  use this new type of laser engraving technology to engrave inside transparent material. 3D Laser Engraving Machine LE-2 is a flexible marking system of modular construction. It consists of laser module and scanning module, which can easily be adapted to the customer's requirements. The laser module of the engraving machine includes laser head, cooling system and power supply. The scanning module consists of XYZ coordinating table, motor drivers, reflection mirror and focus lens. In addition, a robust framework constructed of welded steel section mounted on leveling pads is suitable for assembly or integration of the laser module and scanning module as well as the necessary electrical circuits. The framework can be enclosed completely. A sliding door is assembled on the framework, which provides the necessary protective enclosure for surrounding the marking area according to Laser Safety
      2. LE-2 3D laser engraving machine is a device which meets the requirements of medium-sized and small production. This engraving machine can be equipped two or four lens with the features of its easy operation, high precision for controlling, and the reasonable price in the market.
