How should the co2 laser cutting machine be maintained?

1. Fan cleaning

The long-term use of the fan will cause a lot of solid dust to accumulate inside the fan, making the fan produce a lot of noise, which is not conducive to exhaust and deodorization. When the fan has insufficient suction and poor smoke exhaust, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, pull the fan blades inside until it is clean, and then install the fan.

2. Cleaning of the lens (it is recommended to clean it before work every day, and the equipment must be turned off)

There are 3 reflectors and 1 focusing lens on the engraving machine (reflector No. 1 is located at the emission outlet of the laser tube, that is, the upper left corner of the machine, reflector No. 2 is located at the left end of the beam, reflector No. 3 is located at the top of the fixed part of the laser head, and the focusing lens is located in the adjustable lens barrel at the bottom of the laser head). The laser is reflected and focused by these lenses and then emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser loss or lens damage. When cleaning, do not remove the No. 1 and No. 2 lenses. Just wipe the lens paper dipped in cleaning fluid carefully from the center of the lens to the edge in a rotating manner. The No. 3 lens and the focusing lens need to be taken out of the lens frame and wiped in the same way. After wiping, they can be put back as they are.

Note: 1. The lens should be wiped gently without damaging the surface coating; 2. The wiping process should be handled with care to prevent falling; 3. When installing the focusing lens, please be sure to keep the concave surface downward.

3. Cleaning of the guide rail (it is recommended to clean it once every half a month, and shut down the machine)

As one of the core components of the equipment, the guide rail and linear axis have the function of guiding and supporting. In order to ensure that the machine has a high processing accuracy, its guide rails and linear axes are required to have high guiding accuracy and good movement stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing of the workpiece. These smoke and dust will be deposited on the surface of the guide rail and linear shaft for a long time, which will have a great impact on the processing accuracy of the equipment, and will form corrosion points on the surface of the guide rail and linear shaft, shortening the service life of the equipment. In order to make the machine work normally and stably and ensure the processing quality of the product, the daily maintenance of the guide rail and linear shaft should be done carefully.

Note: Please prepare dry cotton cloth and lubricating oil for cleaning the guide rail

4.tightening of screws and couplings

After the motion system has been working for a period of time, the screws and couplings at the motion connection 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 problems are found, they should be tightened and maintained in time. At the same time, the machine should use tools to tighten the screws one by one after a period of time. The first tightening should be about one month after the equipment is used.

5. Check the optical path

 The optical path system of the laser engraving machine is completed by the reflection of the reflector and the focusing of the focusing mirror. There is no offset problem of the focusing mirror in the optical path, but the three reflectors are fixed by the mechanical part, and the possibility of offset is relatively large. Although it usually does not offset, it is recommended that users must check whether the optical path is normal before each work.
