The current laser cutting machines can be said to be high-power processing equipment. The price of a laser cutting machine ranges from tens of thousands to hundreds of thousands, and the ultra-high power is more than one million. Therefore, attention must be paid in the operation, and the daily maintenance of the laser cutting machine is not careless. To take a simple example, some customers will place the painting operation area near the processing area of the laser cutting machine, It may have no impact in the short term, but in the long run, it will corrode the electrical accessories of the laser cutting machine, thus affecting the cutting quality of the laser cutting machine.
1. Water tank cleaning and water replacement
Suggestion: clean the water tank and replace the circulating water once a week
The service life of the laser tube is related to the water quality and temperature of the circulating water. It is recommended to use pure water and control the water temperature below 35 ℃. If the temperature exceeds 35 ℃, replace the circulating water or add ice to the water tank to reduce the water temperature; Conditional users can choose the chiller or use two water tanks, and the water in the tank is recommended to be replaced once a week.
2. Fan cleaning
If the fan is used for a long time, a lot of solid dust will accumulate in the fan, which will 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, remove the air inlet pipe and air outlet pipe on the fan, remove the dust inside, then turn the fan upside down, pull out the blades inside until it is clean, and then install the fan.
3. Cleaning of lenses
Suggestion: Clean before working every day, and the equipment must be shut down.
be careful:
(1) The lens shall be wiped gently without damaging the surface coating;
(2) The wiping process shall be handled with care to prevent falling;
(3) Keep the concave side downward when installing the focusing mirror.
The laser cutting machine generally has a reflector and a focusing lens, through which the laser is reflected and focused and then shot from the laser hair. The lens is easy to be stained with dust or other pollutants, causing laser loss or lens damage. The lens is easy to be stained with dust or other pollutants, causing laser loss or lens damage. Therefore, it is necessary to clean the lenses every day and replace them as they are.
4. Cleaning of mechanical parts
Suggestion: Clean once every half month and shut down the machine.
Note: Please prepare dry cotton cloth and lubricating oil to clean the guide rail.
The guide rail of the cutter is divided into linear guide rail and roller guide rail,
Cleaning of linear guide rail: Wipe it with dry cotton cloth until it is bright, and then add a little lubricating oil (sewing oil can be used instead of oil). Slowly push the laser head left and right for several times to make the lubricating oil evenly distributed.
Cleaning of roller guide rail: wipe the contact area between the guide rail on both sides and the roller with dry cotton cloth, and then move the beam to clean the rest.
As one of the important parts of the equipment, the guide rail and linear shaft play a guiding and supporting role. In order to ensure that the machine has a high processing accuracy, its guide rails and straight lines are required to have a high guidance accuracy and good motion stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be produced during the processing of the machined parts. As a result, these smoke and dust will be deposited on the surface of the guide rail and linear shaft for a long time, which has a great impact on the processing accuracy of the equipment, and will form corrosion spots on the surface of the linear shaft of the guide rail, shortening the service life of the equipment. In order to ensure the normal and stable operation of the machine and the processing quality of the product, the daily maintenance of the guide rail and linear shaft should be carefully done.
5. Fastening of screws and couplings
After the movement system works for a period of time, the screws and couplings at the movement joints will become loose, which will affect the stability of the mechanical movement. Therefore, during the operation of the machine, it is necessary to observe whether there are abnormal noises or abnormal phenomena in the transmission parts, and if any problems are found, it is necessary to strengthen and maintain them in time. At the same time, the machine should use tools to firm the screws one by one after a period of time. It shall be firm about one month after the equipment is used.
6. Inspection of optical path
The optical path system of the laser cutting machine is jointly completed by the reflection of the reflector and the focusing of the focusing mirror. In the optical path, the focusing mirror does not have the problem of deviation, but the three reflectors are fixed by the mechanical part, which has a high possibility of deviation. Although usually there is no deviation, it is recommended that the user check whether the optical path is normal before each work.
Regular routine maintenance of the laser cutting machine will effectively reduce the impact of the environment on the components, so that they can run efficiently and trouble free for a long time.
