The appearance of laser marking machine is a major leap in the field of laser marking. It is no longer limited to the surface shape of the processing object on the class plane, but can be extended to the three-dimensional surface, so as to complete the efficient laser graphic marking and surface micro-structure production of three-dimensional curved surface objects. Compared with traditional two-dimensional laser marking machines, laser marking machines have the following advantages:

1. Variable focal length, complete 3D marking, because 3D marking can quickly change the focal length of the laser and the direction of the laser beam, so it can complete the surface that could not be completed by 2D marking before. After using 3D marking, the cylindrical marking on the light projection scale can be completed at one time, which greatly improves the processing efficiency. In addition, the appearance shape of many parts of industrial products is not only flat, which is really not enough for two-dimensional marking processing. At this time, 3D marking is easier to complete.

2. The light effect of larger scale and more precise three-dimensional marking can be divided into front focus and back focus. When using the pre-focus mode, the main purpose is to achieve a larger marking scale. Generally, larger x-axis and y-axis deflection lenses are used to make the incident laser spot larger, resulting in a smaller focused spot and higher energy density. Then meet the marking requirements of larger areas.

3. More suitable for deep engraving Traditional 2D marking has inherent shortcomings in deep engraving on the surface of objects. 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 of deep engraving. and efficiency. 3D marking for deep engraving processing does not have the above problems, which not only ensures the effect, but also improves the efficiency. The 3D laser marking machine has improved the application scale of skills for laser marking processing and broadened the demand for curved surface marking.
