There are two types of CO2 laser marking machines: metal tubes and glass tubes. What is the difference between the two?
1. The metal tubes of CO2 laser marking machines are imported, and the glass tubes are domestically made. The service life of metal tubes can reach more than 45,000 hours, and they can generally be used for about 6 years. When the gas in them runs out, they can be recharged and then used again, which is reusable. But glass tubes can generally be used for about 2,000 hours, and generally we need to replace them once every half a year, and they cannot be reused.
2. The stability of metal tubes is better than that of glass tubes. Metal tubes are sealed and use a low voltage of 30 volts. But if the glass tube is used in a cutting machine, it generally requires a power supply of more than 10,000 volts. The performance is unstable, and the power supply is prone to aging after long-term work, there are hidden dangers, and it interferes greatly with the control technology system. For example, improper operation can easily burn out the motherboard, and it is more susceptible to voltage and damages its normal function.
3. The spot of the metal tube is 0.07mm, which is fine, high precision, and has little heat impact. It can be used for fine processing, while the spot of the glass tube is 0.25mm, which is more than 3 times that of the RF tube. The spot is coarse, the precision is poor, the light output is unstable, the heat diffusion area is large, and the edge is partially melted or even blackened.
4. The metal tube is air-cooled and can work stably and trouble-free for a long time. The glass tube is water-cooled. If the continuous processing time is too long or the water temperature is not within a constant range, the light is unstable or not bright, and continuous work has a great impact on product quality.
From the above points, we can clearly see that the metal tube of the CO2 laser marking machine is much better than the glass tube, but the price of the metal tube is also much more expensive than the glass tube. If the precision requirements of the processed product are not very high, it is not a problem to use a glass tube. For example, leather, cloth, acrylic, etc. So don’t choose blindly when purchasing equipment. You need to understand the properties of your products and the required equipment, and try samples first.
