1. The fulcrum of the laser tube installation should be reasonable. The fulcrum should be at 1/4 of the total length of the laser tube. Otherwise, the pattern of the laser tube spot will become bad. Some operations will change the spot into several points for a period of time, which will cause the laser power to decline and can not meet the requirements. Therefore, it is necessary to constantly change the tube. Read carefully the Precautions for the Use of Laser Engraving Machine.

2. The cooling system of the laser engraving machine should be grounded, and the water tank and water path should be cleaned frequently. The temperature control point of the cooling temperature control water tank should be reasonable. Otherwise, the laser tube will be simply damaged and the condensation power will be reduced, the cold water head of the tube will fall off, and the life will be greatly shortened. Sometimes, it is impossible to operate, and the tube will be replaced continuously.

3. The water maintenance should be checked and cleaned frequently. The cooling water can not wash the water maintenance float switch or the water maintenance float switch does not reset. The short circuit method cannot be used to solve the urgent problem. The cooling water quality is good, and the aluminum oxide in the nozzle is too severe. It is necessary to regularly clean the water pump and water pipe and the dirt in the water maintenance after a period of use, otherwise the laser tube will burst or the cold water head will fall.

4. The air suction device should be regularly checked and sorted out, and the air duct of the fan should be cleaned up. Otherwise, a lot of smoke and dust can not be discharged, which will seriously and rapidly pollute the lens and laser tube, and make the mechanical and electronic components simply oxidized to form poor touch.

5. Check the focusing mirror and reflector. The frame will heat up after operation, and the lens surface will change color and rust; Removal of film and cracking are the targets to be replaced. Especially, many customers use large air pumps and air compressors, which will quickly accumulate water on the lens. Therefore, it is necessary to check the cleanliness and quality of the lens (laser tube outlet) optical system on time.

6. The working environment of the machine should not be too bad. If the ambient temperature is higher than 30 ℃ and lower than 18 ℃, there will be too much dust and serious air pollution, so the machine will be severely damaged and the failure rate will continue to rise; It is very simple to have problems with various electrical accessories in a humid environment. Therefore, the customer is reminded to improve the working environment and maintain the machine frequently.
