The maintenance of the laser cutting machine can be roughly performed from the following aspects:

Fan cleaning:

The long-term use of the fan in the machine will cause a lot of solid dust to accumulate in the fan, which will make the fan generate a lot of noise, which is also not conducive to exhaust and deodorization. When the suction power of the fan is insufficient, the fan must be cleaned.

Replacement of circulating water and tank cleaning:

Before the machine works, make sure that the laser tube is filled with circulating water. The water quality and temperature of the circulating water directly affect the life of the laser tube. Therefore, it is necessary to periodically replace the circulating water and clean the water tank. This is usually done once a week.

Lens cleaning:

There will be some mirrors and focusing mirrors on the machine. The laser light is reflected and focused by these lenses and emitted from the laser head. The lens can be easily contaminated by dust or other contaminants, causing laser loss or lens damage. So clean the lenses every day.
When cleaning, pay attention to:
1. The lens should be wiped gently, so as not to damage the surface coating;

2. Handle gently during wiping process to prevent falling;

3. Please keep the concave surface downward when installing the focusing lens.

Fastening of screws and couplings:

After the motion system works for a period of time, the screws and couplings at the motion joints will loosen, which will affect the smoothness of the mechanical movement. Therefore, during the operation of the machine, observe whether there are abnormal noises or abnormal phenomena in the transmission parts, and find the problems in time. Robust and maintenance. At the same time, the machine should be used to tighten the screws one by one after a period of time. The first solidification should be about one month after the equipment is used.

Rail cleaning:

Guide rails and linear shafts are one of the core components of the equipment, and their functions are to guide and support. In order to ensure the machine has a high processing accuracy, it is required that the guide rails and straight lines have high guiding accuracy and good motion stability. During the operation of the equipment, due to the large amount of corrosive dust and fumes produced by the workpiece during processing, these fumes and dust have been deposited on the surface of the guide rail and the linear axis for a long time, which has a great impact on the processing accuracy of the equipment and will Corrosion spots are formed on the surface of the linear axis of the guide rail, which shortens the service life of the equipment. So clean the machine guide every half a month. Turn off the machine before cleaning.

Inspection of light path:

The optical path system of the machine is completed by the reflection of the mirror and the focusing of the focusing lens.  There is no offset problem in the focusing lens in the optical path. But the three mirrors are fixed by the mechanical part. And the possibility of offset is large.  Although there is usually no offset. It is recommended that users check whether the optical path is normal before each work.
