What is the working principle of laser engraving machine

Laser engraving machine with a small part of the laser beam focus in material, make the material evaporate quickly, a bit like a magnifying glass, placed in the sun burning something in focus. Compared with the other USES laser, laser engraving machine laser power is not very big. For convenient operation and safe, laser engraving machine is a complete, completely closed to design and manufacture of the equipment. According to the principle of its processing, laser carving machine machine can be divided into mechanical engraving machine engraving machine, laser engraving machine, sand blasting, water knife cutting machine, etc. Not only can the same laser carving machine carving, can also be used to cut not too thick material. In a word, laser engraving machine compared with mechanical engraving machine has the following advantages: one is better than mechanical engraving machine speed, high efficiency. Second, more accurate, more can sculpture complex image design. 1. Small gap cutting three-dimensional characters, font deformation is small, organic glass cutting edge character no wool, do not need polishing processing. 2, can be carved, cut glass, leather, rubber foam board and other special materials. For example, cutting, carving object does not need special fixed. Laser compared with the traditional machining method has many advantages, one is the laser engraving or tags do not contact with material, so the traditional carving tools will not be lost. It also reduces the potential unqualified products. Laser notch sustained, concise and clear. Although sometimes need to trial and error to find the correct parameters, but the laser carved carved is much faster than the traditional mechanical. Due to the principle of carving is very different, the laser can be carved out many traditional methods cannot engraving materials, including metal, plastic, etc.
