CO2 laser cutting machine is an important laser cutting machine. Its daily maintenance is also very important. What are the main maintenance methods?
1. Water replacement and water tank cleaning (it is recommended to clean the water tank and replace the circulating water once a week)
Note: make sure that the laser tube is full of circulating water before the machine works.
The quality and water temperature of circulating water directly affect the service life of laser tube. It is recommended to use pure water and control the water temperature below 35 ℃. If the temperature is over 35 ℃, the circulating water shall be replaced, or ice shall be added to the water to reduce the water temperature. (it is recommended that the user choose a cooler, or use two water tanks).
Clean the water tank: first, turn off the power supply, pull out the water inlet pipe, let the water in the laser pipe flow into the water tank automatically, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, return the water pump to the water tank, insert the water pipe connecting the water pump into the water inlet, and arrange the joints. Power up the water pump separately and run it for 2-3 minutes (make the laser tube full of circulating water).
2. Cleaning of fans
The long-term use of the fan will make the fan accumulate a lot of solid dust, make the fan produce a lot of noise, and is not conducive to exhaust and deodorization. When the suction of the fan is insufficient and the smoke exhaust is not smooth, first turn off the power supply, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, pull the inner blades until they are clean, and then install the fan.
3. Lens cleaning (it is recommended to clean before work every day, and the equipment must be in shutdown state)
In the previous machine introduction, It has been mentioned that there are three mirrors and one focusing mirror on the carving machine (No.1 mirror is located at the emission outlet of the laser tube, i.e. the upper left corner of the machine, No.2 mirror is located at the left end of the beam, No.3 mirror is located at the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable barrel under the laser head). The laser is reflected and focused by these mirrors and then emitted from the laser hair 。 The lens is easy to be stained with dust or other pollutants, resulting in laser loss or lens damage. No. 1 and No. 2 lenses do not need to be removed when cleaning, just carefully wipe the lens paper dipped with cleaning solution along the center to the edge of the lens. No. 3 lens and focusing lens need to be taken out of the frame, wiped with the same method, and then installed as before after wiping.
Attention: ① the lens shall be wiped gently, without damaging the surface coating; ② the lens shall be handled gently to prevent falling during the wiping process; ③ the concave surface shall be kept downward during the installation of focusing lens.
4. Cleaning of guide rail (it is recommended to clean it every half a month and shut down the machine)
As one of the core parts of the equipment, guide rail and linear axis play a guiding and supporting role. In order to ensure the high machining accuracy of the machine, it is required that its guide rail and straight line have high guiding accuracy and good movement stability. During the operation of the equipment, a large number of corrosive dust and smoke will be produced during the processing of the processed parts. Based on the large amount of smoke and dust deposited on the surface of the guide rail and the linear axis for a long time, it has a great impact on the processing accuracy of the equipment, and will form corrosion points on the surface of the linear axis of the guide rail and shorten the service life of the equipment. In order to ensure the normal and stable operation of the machine and the processing quality of the products, the daily maintenance of the guide rail and the linear shaft should be done well.
