What is the difference between the glass tube and the metal tube of the co2 laser marking machine?

Many people still don’t know what a laser marking machine is, but laser marking products can be seen everywhere in our lives. The laser marking machine can leave a permanent mark on the surface of the material. The principle is The high-energy laser beam is used to irradiate the surface layer of the material to expose the deep layer of the material, thereby engraving the required patterns, characters, barcodes, two-dimensional codes and other information.

There are many types of laser marking machines. Different materials require different laser marking machines. The main classifications of laser marking machines are as follows: fiber laser marking machine, ultraviolet laser marking machine, co2 Laser marking machine, green laser marking machine, end pump laser marking machine, UAG laser marking machine, semiconductor laser marking machine, etc.

Laser marking machine is mainly used in some products that require high precision and high precision, and has a wide range of applicability: electronic appliances, hardware products, jewelry, watches and glasses, precision instruments, medical equipment, aerospace ships, electronic components, medical and food packaging , Integrated circuits, building materials, handicrafts, etc.

There are also two types of co2 laser marking machines in 　　 laser marking machines, one is a metal tube and the other is a glass tube. What is the difference between them?

1. The metal tube of the co2 laser marking machine is imported, and the glass tubes are all made in China. The service life of the metal tube can reach more than 45,000 hours. Generally, it can be used for about six years. The gas inside can be used up. Refilling and subsequent use are reusable, while the glass tube is generally used for about 2000 hours, and generally needs to be replaced once every six months. It is a one-time use and cannot be reused.

2. The stability of the metal tube is stronger than that of the glass tube. The metal tube is fully sealed and uses a low voltage of 30 volts. If the glass tube is used on the cutting machine, the power supply is generally more than 10,000 volts, and the performance is unstable. , The power supply is prone to aging when working for a long time, which has potential safety hazards, and has great interference to the control system. If the operation is improper, it is easy to burn the main board, and it is more likely to be affected by the voltage and damage its normal function.

3. The light spot of the co2 metal tube is 0.07mm, the light spot is fine, the precision is high, and the heat impact is small, so it can be finely processed, while the light spot of the glass tube is 0.25mm, which is more than three times that of the radio frequency tube, the light spot is relatively thick, and the accuracy is relatively good Poor, unstable light, large heat diffusion area, melting of cut edges and obvious blackening.

4. The air-cooled co2 metal tube can work stably without failure for a long time. The water-cooled glass tube adopts water cooling. If the continuous processing time is too long or the water temperature is not in a constant range, the light will be unstable or not light, and continuous work will affect the product. The quality of the product has a great impact.
