Laser Marking Machine can also called Laser Engraving Machine. The working principle of Laser Marking Machine is that a high-energy continuous laser beam is generated by laser source, and the focused laser acts on the materials to melt and even vaporize the surface of materials instantly. Controlling the path of laser on the surface of materials to form the required marking results.
Laser marking machine is characterized by non-contact marking, marking on any profiled surface, the workpiece will not deform and generate internal stress. Laser Marking Machine is suitable for marking metal, plastic, glass, ceramic, wood, leather and other materials.
The laser marking machine can mark all parts, such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc. The marking result is wear-resistant, the production process is easy to automate and the marked materials are less deformed.
Laser marking machine adopts the scanning method to work, that is, the laser beam is incident on the two mirrors, and the scanning motor is controlled by the computer to drive the reflect mirrors to rotate along the X axis and Y axis respectively. Finally, laser beam will be focused onto the workpiece, thereby forming marking traces.
There are different kinds of Laser Marking Machine, including Co2 Laser Marking Machine, Semiconductor Side Pump Laser Marking Machine, Semiconductor End Pump Laser Marking Machine and Fiber Laser Marking Machine. Semiconductor End Pump Laser Marking Machine includes Green Laser marking machine and Ultraviolet Laser marking machine. Green laser and Ultraviolet laser are different on wavelength. The wavelength of Green laser is 532nm. The wavelength of Ultraviolet is 355nm.
We mainly introduce the different between Co2 Laser Marking Machine and Ultraviolet Laser Marking Machine and Fiber Laser Marking Machine. These three Laser Marking Machines are popular now, and they can meet most of marking requirements.
Co2 Laser Marking Machine uses Co2 RF laser source or Co2 glass laser tube, the fastest marking speed can reach 7000mm/s. Co2 Laser Marking Machine is suitable for marking on most non-metal materials such as wood, acrylic, paper, plastic, leather, glass, ceramics, etc.
UV Laser Marking Machine is one of semiconductor end pump laser marking machine, equipped with ultraviolet laser and high-speed scanning galvanometer. UV Laser Marking Machine has a very small spotlight. UV laser is the true cold laser, and the thermal effect is very small. Therefore, the UV Laser Marking Machine can perform ultra-fine marking and special material marking. UV laser marking machine is the first choice for customers who have higher requirements for marking result. UV Laser Marking Machine has the characteristics of high electro-optical conversion rate, stable performance, high marking precision, high working efficiency, and modular design for easy installation and maintenance.
Fiber Laser Marking Machine uses fiber laser source, which equipped with high-speed galvanometer scanning system and professional laser marking software. Due to the low price, Fiber Laser Marking Machine is the best-selling Laser Marking Machine. Fiber Laser Marking Machine is smaller than other laser marking machines because of the modular design with air cooling system. Our company has Portable Fiber Laser Marking Machine that is small and easy to move. Compared with other lasers, fiber laser have higher photoelectric conversion efficiency and better laser beam quality, so the lines engraved by fiber laser marking machine are more elaborate. Fiber Laser Marking Machine is suitable for marking on various metal and non-metal materials. But it is not suitable for marking on transparent materials.
