Surface marking select 3D dynamic focus laser marking machine

With the popularization and application of laser marking machines, more and more companies are no longer satisfied with the flat and full marking of products, because some irregular products also need to be marked, so traditional laser marking machines cannot meet the requirements. With the development of the industry, the processing needs of three-dimensional curved surfaces have emerged. It is difficult for traditional two-dimensional laser marking machines to meet such processing needs, so three-dimensional 3D laser marking machines came into being. Surface marking choose 3D dynamic focus laser marking machine.

The emergence of 3D 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, but can be extended to three-dimensional surface Realize high-efficiency laser graphic marking and surface microstructure manufacturing for three-dimensional curved objects. Compared with the traditional two-dimensional laser marking machine, the 3D laser marking machine has the following advantages:

Variable focal length, realizing three-dimensional marking Because 3D marking can quickly change the laser focal length and laser Beam position, so it is possible to mark the surface that could not be realized 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 just flat, and 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 two types: front focus and back focus. When using the front focus mode, the main purpose is to achieve a larger marking range, generally The use of larger X and Y axis deflection lenses can allow the incident laser spot to be larger, resulting in a smaller focused spot and higher energy density; thus meeting the marking requirements of larger areas.

■It is more suitable for deep engraving. Traditional 2D marking has inherent defects in deep engraving on the surface of objects. With the upward movement of the laser focus during the engraving process, the laser energy acting on the actual surface of the object will drop sharply. 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. 3D laser marking machine has improved the technical application range for laser marking processing and expanded the demand for surface marking.
