The maintenance of laser cutting machine can be carried out in the following aspects:
Fan cleaning:
The long-term use of the fan in the machine will lead to the accumulation of a large amount of solid dust 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, the fan must be cleaned.
Replace circulating water and wash water tank:
Before the machine works, make sure that the laser tube is full of circulating water. The quality and temperature of circulating water directly affect the life of the laser tube. Therefore, it is necessary to replace the circulating water and clean the water tank regularly. Usually once a week.
Key points for daily maintenance of laser cutting machine
Lens cleaning:
There will be some mirrors and focus mirrors on the machine. The laser is reflected and focused by these lenses, and then comes out of the laser head. The lens is easily polluted by dust or other pollutants, which may lead to laser loss or lens damage. Therefore, clean the lenses every day.
When cleaning, pay attention to:
1. Wipe the lens gently to avoid damaging the surface coating;
2. Handle with care during wiping to prevent falling;
3. When installing the focusing lens, please keep the concave side downward.
Fastening of screws and couplings:
After the motion system works for a period of time, the screws and couplings at the motion joints will become loose, which will affect the stability of mechanical movement. Therefore, during the operation of the machine, observe whether the transmission parts have abnormal sound or abnormal phenomena, and find out the problems in time. Robust and maintenance. At the same time, use the machine to tighten the screws one by one after a period of time. The first curing shall be about one month after the equipment is used.
Guide rail cleaning:
The guide rail and linear axis are one of the core components of the equipment, whose function is to guide and support. In order to ensure that the machine has a high processing accuracy, 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 workpiece, which have been deposited on the surface of the guide rail and the linear shaft for a long time. This will have 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, thus shortening the service life of the equipment. Therefore, clean the machine guides every half month. Turn off the machine before cleaning.
Check the optical path:
The optical system of the machine is completed by the reflection of the mirror and the focusing of the focusing lens. The focusing lens has no offset problem on the optical path. However, the three mirrors are fixed by mechanical components. And the possibility of deviation is very high. Although there is usually no offset. It is recommended that the user check whether the optical path is normal before each operation.
