Laser engraving machine is also a type of laser marking machine. In daily use and maintenance, we need to master the methods and careful maintenance in order to make the machine more stable and play its role. So first we should know some precautions for laser engraving machines. Please check as follows:
The following points are listed below:
Grounding protection of laser engraving machine
The cooling water of the laser engraving machine
The cleaning of the laser engraving machine
The temperature of the laser engraving machine
The high power of the laser engraving machine
The fan maintenance of the laser engraving machine
The laser power source and machine tool of the laser grounding machine must have good grounding protection. The necessity of the ground wire to be less than 4Ω is:
(1) Can guarantee the normal operation of the laser power supply,
(2) can extend the life of the laser tube,
(3) Prevent external machine tools from causing machine tool bounce.
(4) Prevent accidental circuit damage caused by high voltage discharge.
The cooling water of the laser engraving machine should be unblocked. Regardless of whether you use tap water or a circulating water pump, you must keep the water flowing. The cooling water is the heat generated by the laser tube. The higher the water temperature, the lower the light output power (water temperature 15-20 ° C is preferred); when the water is broken, the tube end will burst due to the heat accumulated in the laser cavity, and even the laser will be damaged. power supply. Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe is hardly bent (dead bend) or falls off, and the pump fails, it must be repaired in time to avoid power failure or even damage to the equipment.
Cleaning and maintenance, good exhaust, cleaning and maintenance of the machine at any time is a necessary condition for the normal operation of the machine. Imagine if people's joints were not flexible, what would they do? Machine tool guides are the core component of high precision. After each job is done, it must be wiped clean and kept clean and smooth. The bearings should also be oiled regularly to make the transmission flexible, accurate and extend the service life of the machine.
Ambient temperature and humidity The ambient temperature should be in the range of 5-35 ° C. It should be noted that if used in sub-zero environments, it must be done:
(1) Prevent the circulating water in the laser tube from freezing, and the water must be completely discharged after closing;
(2) When starting up the laser engraving machine, the laser current must be preheated 5. The working time is more than 1 minute. In rainy and humid environments, the laser power supply takes longer to warm up. In order to prevent breakdown of high voltage circuits, it is necessary to apply high voltage after draining water.
Keep away from the sudden high-power interference caused by high-power and strong-vibration equipment, which sometimes causes machine failure. Although rare, it should be avoided. Therefore, large electric welding machines, large electric mixers, and large power transmission and transformation equipment should be kept away. Strong vibration equipment is self-evident, such as forging presses, vibrations generated when walking close-range motor vehicles, etc., the obvious vibration of the ground is very detrimental to precision carving.
Fan maintenance: After the fan is operated for a period of time, a large amount of dust will accumulate in the fan and the exhaust pipe. Dust will affect the exhaust efficiency of the fan and cause a large amount of soot emission. Maintenance method: loosen the connection hose between the exhaust pipe and the fan, remove the exhaust pipe, and remove the dust on the exhaust pipe and the fan. Maintenance period: about one month.
In conclusion, the laser engraving machine need careful settings and use, we also provide Laser Cutting Machine, CNC Wood Working Machine, follow us now.
