In general, the metal laser cutting machine will not have too big problems in the process of operation. However, we need to maintain the equipment frequently and pay more attention to some details during the operation of the equipment. The price of laser cutting machine is not low, ranging from hundreds of thousands to millions. Therefore, to prolong the service life of the laser cutting machine as much as possible can better save production costs and win greater benefits.

This shows that the daily maintenance of the laser cutting machine is very important.

The following is mainly explained from six aspects:

1、 Replacement of circulating water and cleaning of water tank: Make sure that the laser tube is full of circulating water before the machine works. The quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, the circulating water shall be replaced regularly and the water tank shall be cleaned. This is best done once a week.

2、 Fan cleaning: The fan in the machine will accumulate a lot of solid dust in the fan after being used for a long time, 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 is not smooth, the fan should be cleaned.

3、 Lens cleaning: there will be some reflectors and focusing mirrors on the machine. The laser is reflected and focused by these lenses and then emitted from the laser hair. The lens is easy to be stained with dust or other pollutants, causing laser loss or lens damage. So clean the lenses every day. Pay attention to:

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. When installing the focusing mirror, be sure to keep the concave side downward.

4、 Guide rail cleaning: As one of the core 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. Therefore, clean the machine guide rails every half month. Shut down the machine before cleaning.

5、 Fastening of screws and couplings. At the same time, the machine should use tools to firm the screws one by one after a period of time. The first time of firming shall be about one month after the equipment is used.

6、 Inspection of optical path: the optical path system of the 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 generally there is no deviation, it is recommended that the user must check whether the optical path is normal before each operation.

In recent years, laser cutting machine manufacturers have paid more and more attention to the stability of laser cutting machines. The stability of laser cutting machines has a lot to do with several important parts. With good quality parts, laser cutting machines are naturally very stable when they are used.

This problem has led many customers to hesitate between import and domestic when purchasing laser cutting machines. Some users even worry that the stability of domestic laser cutting machine will decline after a long time of work. In fact, there is no need to worry about this. Domestic laser equipment has already had a good foundation and R&D technology. In fact, its performance does not have to be worse than that of the imported ones. Therefore, the stability of the laser cutting machine cannot be generalized. It needs to be improved slowly with continuous improvement and improvement of technology. At the same time, whether the laser cutting machine is stable in use depends on your later maintenance and working environment.
