Laser marking machine is one of the marking equipment and one of the most widely used marking methods in recent years. Laser marking uses high-energy laser pulses to locally heat the small area of the workpiece. The energy radiated by the laser is directed to the interior of the workpiece through heat transfer, and the workpiece is melted to form a specific molten pool, because the laser marking power density is high and the energy is released quickly, Therefore, the processing efficiency is much higher than the traditional marking method. After the laser is focused, the spot is small. In the marking process, the adhesion between the two materials can be better, which will not cause damage and deformation of the surface of the material, and there is no need for post-treatment of the marking seam.
Laser marking machine has unique processing and manufacturing characteristics, which makes laser marking machine more and more used in industrial production and higher marking efficiency. Laser marking machine has great characteristics in its manufacturing process. Such as: non-contact processing, laser marking machine does not need to process and surface treatment of the workpiece. Moreover, short-time marking has no impact on the outside world, and has little impact on the thermal deformation and influence area of the material itself. It is especially suitable for laser marking of high melting point, high hardness and special materials. In addition, the laser marking machine has small marking points and high energy density, which is suitable for high-speed laser marking.
The laser marking machine uses the excellent directivity of the laser beam to mark, focuses the laser beam in a small area through the optical system, and forms a heat source area with high energy concentration in a very short time, so as to form firm marking points and marking seams at the marked object, which is the basic principle and basic characteristics of the laser marking machine.
The above are the commonly used laser marking methods, which are applicable to all aspects of industrial production. The laser marking machine has a wide range of applications and can bring more convenience to industrial production.
