The Difference Between 2D Laser Marking Machine And 3D Laser Marking Machine
As the development of industrial level, laser marking carft get more attention from worldwide. This is must inevitable. Because it is high efficienicy, green and environmentally friendly, this kind of process wins the favor of more and more users certainly.
The common two-dimensional laser marking machine has been widely used in the plane marking of various products. The 3D laser marking machine can realize the research and development of high-quality marking equipment for three-dimensional surface. And it has become a research hot spot and important point for market development gradually.
First, a wider range and finer effects. There are two types marking of 3D machine : front focusing and rear focusing. When the front focusing mode adopts, the main purpose is to achieve a larger marking range. Generally, the X and Y axis deflection lenses is larger, incident laser spots is larger and obtain smaller focusing spots with higher laser beam energy density. So as to meet the standard requirements of a larger area. The marking area could bigger than the regular 2D marking machine twice and sometimes even 3 times.
Second, the focal length can change to realize three-dimensional marking. Because 3D marking can quickly change the focal length of laser and the position of laser beam. So it is possible to mark curved surfaces that cannot be realized in 2D in the past. After using 3D marking, the marking area is not limit by X and Y axis. There is one more axis—Z axis, then the marking area become to tridimensional. Thus, it can achieve marking on surface of irregualer shape obeject. At this time, 3D marking is easier to realize.
Third, it is more suitable for deep carving. There are inherent defects in traditional 2D marking for deep carving on the surface of objects. The laser focus moves up in the carving process. So the laser energy acting on the actual surface of objects will drop sharply. And it seriously affects the effect and efficiency of deep carving. 3D marking for deep engraving processing does not have the above problems, which not only ensures the effect but also improves the efficiency.
