The laser marking machine can leave a permanent mark on the surface of the article. The principle is to irradiate the surface of the product with a high-energy laser beam to evaporate and expose the deep material, thereby engraving exquisite patterns, text, two-dimensional codes, barcodes, etc. Laser marking machine is mainly divided into: fiber laser marking machine, co2 laser marking machine, YAG laser marking machine, ultraviolet laser marking machine, green laser marking machine, etc.
At present, laser marking machines are mainly used in some high-precision, high-precision products, widely used in: integrated circuits, electronic communications, hardware products, precision instruments, watches and glasses, jewelry, food packaging, electronic components, electrical appliances, building materials, etc.
1. The RF tubes of the co2 laser marking machine are imported, and the glass tubes are domestically produced. The service life of the laser of the radio frequency tube can reach more than 45,000 hours, and it is generally used for about 6 years without any problems, while the general use of the glass tube is 2500 hours, and the glass tube needs to be replaced once in about half a year.
2. The air-cooled radio frequency tube of the co2 laser marking machine can be used stably without failure for a long time. The glass tube is water-cooled, and the continuous processing time of the equipment is too long or the water temperature is not within the constant range. Work has a greater impact on the quality of the product.
3. The stable type of the co2 radio frequency tube is relatively strong. The radio frequency tube is a fully sealed metal tube and uses a 30-volt bottom voltage power supply, which directly avoids some hidden dangers caused by the use of high-voltage power supplies. The glass tube is a laser cutting machine. Generally, a high-voltage power supply above 10,000 volts is used. In addition to being unstable, there is a certain degree of danger. Working for a long time makes the power supply easy to age, and has great interference to the control system. If the operation is improper, it is easier to burn the main board. The normal function is damaged due to the influence of voltage.
4. The co2 radio frequency tube has a light spot of 0.07mm, with fine light spot, high accuracy, and small thermal diffusion area. It can be finely processed. The glass tube has a light spot of 0.25mm, which is more than three times that of a radio frequency tube. The light spot is relatively coarse and accurate. Relatively poor, unstable light, large heat diffusion area, melting of the cut edges, and obvious blackening.
Based on the above, it can be seen that the RF tube is much better than the glass tube. Of course, you get what you pay for. The price of the RF tube is also much more expensive than the glass tube. If it is not a product with high precision requirements, such as: leather, cloth, Acrylic, etc., you only need to use a glass tube to be fully competent, so when purchasing equipment, do not choose blindly. It is correct to choose the one that suits your needs.
