The emergence of 3D laser marking machine is a major leap in the field of laser marking. The surface shape of the processed object is no longer limited to the plane-like surface and can be extended to three-dimensional surface to achieve high-efficiency laser marking of three-dimensional curved objects. And surface microstructure manufacturing.
Variable focal length to achieve three-dimensional marking. Because 3D marking can quickly change the laser focal length and laser beam position, it is 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 marked once. The completion greatly improves the processing efficiency. Moreover, the surface shape of many parts of industrial products is not just a flat surface. It is really powerless for 2D marking processing. At this time, 3D marking is easier to achieve.
Larger range and finer light effect 3D marking can be divided into front focus and back focus. When the front focus mode is used, the main purpose is to achieve a larger marking range. Generally, a larger XY axis deflection lens can be used. It allows the incident laser spot to be larger to get a smaller focused spot, and the energy density is higher to meet the marking requirements of a larger area.
It is more suitable for deep engraving. Traditional 2D marking for deep engraving of the object surface has inherent defects. As the laser focus moves up during the engraving process, the amount of laser acting on the actual surface of the object will drop sharply, which seriously affects the effect of deep engraving. efficient. 3D marking for deep engraving and processing does not have the above problems, which not only guarantees the effect but also improves the efficiency. The 3D laser marking machine has improved the scope of technical application for laser marking processing and expanded the demand for surface marking.
