[0002] Laser marking machine is a kind of equipment that uses high-energy-density laser beam to make permanent mark on the surface of various materials. It makes the surface layer material vaporize or have color change chemical reaction through the interaction between laser beam and material surface, thereby leaving clear and durable mark. Bearing bush laser marking machine is a special equipment for laser marking of bearing bush. The working principle of bearing bush laser marking machine is mainly based on the thermal processing effect of laser. When high-energy-density laser beam irradiates the surface of bearing bush, the surface of bearing bush absorbs laser energy, and thermal excitation process occurs in the irradiation area, which causes the surface temperature of the material to rise, resulting in vaporization, melting, ablation and other phenomena, thereby leaving the required mark pattern or text on the surface of bearing bush. Laser marking is fast, and a large number of bearing bush marking work can be completed in a short time, improving production efficiency. The size of focused laser beam is extremely small, which can achieve fine marking effect and meet the high-precision requirements of bearing bush marking. The marking effect of laser marking is durable and not easy to wear or fall off, which can keep clear and distinguishable for a long time. Laser marking is a non-contact processing method, which will not cause mechanical damage or stress to the surface of bearing bush, ensuring the integrity and performance of bearing bush.
