CO2 laser marking machine commonly used laser tube is divided into glass tube and radio frequency tube, the difference between the two is:
1, laser tube: CO2 radio frequency tube laser marking machine adopts imported laser tube; And the glass tube uses domestic laser tube.
2, service life: CO2 radio frequency tube laser marking machine life can reach more than 45,000 hours, generally can be used for 6 years, inflatable can be reused, do not replace; And the glass tube marking machine is only about 2500 hours, generally replace a glass tube half a year, not reusable, to replace.
3, cooling mode: CO2 radio frequency tube laser marking machine adopts air cooling, can ensure long-term trouble-free stable operation; CO2 glass tube laser marking machine uses water cooling, long working time or high water temperature may not light or intermittent light, continuous work has a great impact on the quality of the product.
4, spot size (beam) : CO2 radio frequency tube laser marking machine is 0.07mm spot fine, 3 times more than the glass tube fine, high precision, small thermal diffusion area, can be carved/cut very fine works; CO2 glass tube laser marking machine is 0.25mm light spot thick, poor accuracy, light instability (light intensity is not uniform, sometimes no light), thermal diffusion area is large, cutting edge melting, blackening is obvious, engraving accuracy is poor.
5, stability: radio frequency tube is fully sealed metal tube, the use of 30 volt low voltage power supply, which is directly to avoid the use of high voltage power supply brought about by some of the drawbacks; Because of the domestic glass tube laser cutting machine use is 10000 v or more high voltage power supply, there is a certain risk, in addition to the unstable working long hours make power easy ageing, and the control system has a lot of interference, such as improper operation is easy to burn out the mainboard is more susceptible to the influence of the voltage and damage to its normal function.
