Laser marking machine in use and maintenance needs to master methods and careful maintenance, in order to make the machine more stable to play its role.

1. Good grounding laser power supply for laser marking machine and machine tool body must have good grounding protection. Grounding wire should be used with special line less than 4. The necessity of grounding is:

(1) It can ensure the normal operation of laser power supply.

(2) Laser service life can be prolonged.

(3) It can prevent machine tool runout caused by external interference.

(4) Prevent high voltage discharge from occasional circuit damage.

2. If the cooling water of laser marking machine is to be unblocked, whether it is running water or circulating water pump, it must be kept unblocked. Cooling water takes away the heat generated by the laser. The higher the water temperature, the lower the light output power (15-20 C water temperature is the best); when water is cut off, the power will decrease because of the heat accumulation in the laser cavity, and even damage the laser source. Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, even when the pump fails, it must be stopped and repaired in time to avoid power decline or even damage to the equipment.

3. The ambient temperature and humidity should be in the range of 0-45 C. Particular attention is paid to the following: if used in the environment below freezing point (0 C), it must be done:

(1) To prevent the freezing of circulating water in the laser, the water must be emitted thoroughly after shutdown.

(2) When starting, the laser must be preheated for more than 5 minutes before it can work.

4. Keep away from the sudden interference of large power and strong vibration equipment, which sometimes causes machine failure. Although it is rare, it should be avoided as far as possible. Therefore, such as large welding machines, giant electric mixers and large power transmission and transformation equipment, should be far away. Strong vibration equipment is self-evident, such as forging press, vibration caused by close-range motor vehicles, etc. The obvious ground shaking is very disadvantageous to accurate marking.

5. Maintain and control the stability of PC. Control PC is mainly used for marking equipment control. In addition to installing necessary graphic design software, do not make special aircraft.

6. Lens maintenance: After a period of time, the machine will stick a layer of ash on the surface because of the working environment, which will reduce the reflectivity of the mirror and the transmittance of the lens, and ultimately affect the laser power. Please cover the lens when you stop using it. Maintenance method: Use degreased cotton dipped in ethanol to gently wipe the lens surface clockwise and remove dust. In a word, we should always do the precautions of laser marking machine, so as to greatly improve the life and work efficiency of our machine.
