The principle of UV laser marking machine is similar to the other laser marking machine, all use laser beam to mark permanently on the surface of various materials. The marking effect is that the short-wavelength laser directly interrupts the molecular chain of the substance (unlike the long wave generated by the laser evaporation of the surface material exposing the deep substance) to show the desired etching patterns and features. So how long is the service life time of the machine and how to maintain the machine to make it service longer, we will explore the issues in this article.
The following knowledge points are listed below:
The service life time of UV laser marking machine
How to prolong the life time of UV laser marking machine
UV laser marking machine uses 355nm UV laser marking. It can greatly reduce the mechanical deformation of the material, and the processing thermal power is small. The effective light output time of the ultraviolet laser is 12000-14000 hours. According to the average use frequency and working time of the laser, the effective working time of the laser is 2-3 years. So do you need to replace the laser source within 2-3 years? No, because effective service does not mean that the equipment will not work. So the actual working time is far more longer than that.
(1) Whether the cooling water is tap water or circulating water pump, it must be kept smooth, and the water flow must be kept smooth. The cooling water of the UV laser marking machine is used to take away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (the water temperature is preferably 15-20 ℃). When the water is cut, due to the heat accumulated in the laser cavity, the tube end will burst, and even damage the laser. Therefore, it is very necessary to check whether the cooling water is smooth at any time.
(2) The necessary conditions for the normal operation of the UV laser marking machine include cleaning and maintenance, good ventilation, and cleaning the machine at any time. If our joints are not flexible, we cannot move. Similarly, the machine tool guide rail is also a core component of high precision. Every job must be cleaned, kept clean and lubricated. Each bearing must also be lubricated regularly, so that the transmission can be processed flexibly and accurately, extending the life of the machine.
(3) Ambient temperature and humidity The ambient temperature should be within the range of 5-35 ℃.
(4) Keep away from strong battery impact, which may sometimes cause the UV laser marking machine failure. Although this situation is rare, it should be avoided as much as possible. Such as large electric welders, large electric mixers, large power transmission and transformation equipment, etc., should be kept away. Strong vibration equipment is self-explanatory, such as vibration caused by forging presses and short-distance motor vehicles. The obvious shaking of the ground is very detrimental to accurate engraving.
(5) As long as the lightning protection measures of the building are reliable, lightning protection can be achieved. And good grounding can also help prevent lightning. Special note: In unstable areas (such as voltage fluctuations exceeding 5%), please install a stabilized power supply with a capacity of at least 3000w to prevent voltage surges from burning the circuit or computer.
(6) Maintain and control the stability of the PC of the UV laser marking machine. Control PC is mainly used for the control of engraving equipment. In addition to installing the necessary graphic design software, please do not use special planes. As the computer adds a network card and antivirus firewall, it will seriously affect the speed of the control machine. Please do not install anti-virus firewall on the controller. If you need a network card for data communication, please turn off the network card before starting the laser engraving machine.
So now you know the lifetime of the UV laser marking machine，Portable fiber laser marking machine，Table type fiber laser marking machine?
