Advantage:3d VS 2D laser marking machine

3D dynamic focus laser marking is a laser surface depression processing method. Compared with traditional 2D laser marking, 3D marking has greatly reduced the surface flatness requirements of the processed object, and the processing effects are more colorful and more effective. Creative processing technology came into being.

In the field of coding and marking, the traditional two-dimensional laser marking machine has been widely used in the plane marking of various products, but with the development of the industry, the processing requirements for three-dimensional curved surfaces have emerged, (such as: mobile phone antennas, three-dimensional circuits) Etc.) The traditional two-dimensional laser marking machine is difficult to meet such processing requirements, so the three-dimensional 3D dynamic focus laser marking machine came into being.

The emergence of 3D dynamic focus laser marking machine is a major leap in the field of laser marking. Its surface shape of the processed object is no longer limited to the plane-like surface. It can be extended to three-dimensional surfaces to achieve high-efficiency lasers for three-dimensional curved objects. Graphic marking and surface microstructure manufacturing.

Compared with traditional 2D laser marking machine, 3D dynamic focus laser marking machine has the following advantages:

1. Variable focal length to realize three-dimensional marking
Because 3D marking can quickly change the laser focal length and laser beam position, it becomes possible to mark curved surfaces that cannot be achieved in 2D in the past. After using 3D marking, the cylindrical marking in the light projection range can be completed at one time, which greatly improves the processing efficiency. Furthermore, the surface shape of many parts of industrial products is not only flat, it is really powerless for 2D marking processing. At this time, 3D marking is easier to achieve.

2, more suitable for deep carving
Traditional 2D marking has inherent defects in deep engraving of the object surface. As the laser focus moves up during the engraving process, the laser energy acting on the actual surface of the object will drop sharply, which seriously affects the effect and efficiency of deep engraving.

For the traditional deep engraving method, the lifting table is moved to a certain height at regular intervals during the engraving process to ensure that the laser surface is well focused. 3D marking for deep engraving processing does not have the above problems, which not only guarantees the effect, but also improves the efficiency, and at the same time saves the cost of the electric lifting table.

3. Larger range and finer light effect
3D marking can be divided into front focus and back focus. When using the front focus mode, the main purpose is to achieve a larger marking range. Generally, larger X and Y axis deflection lenses are used, which can allow the incident laser spot to be more Larger, a smaller focused spot is obtained, and the energy density is higher; thereby meeting the requirements of a larger area.
