The price of laser cutting machine is not low, ranging from hundreds of thousands to millions. In this way, the service life of the laser cutting machine will be extended as far as possible to better save production costs and win greater benefits. This shows that the daily maintenance of the laser cutting machine is very important. The following are mainly described from several aspects:

First, replace the circulating water and clean the 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 service life of laser tubes. Therefore, it is necessary to replace the circulating water and clean the water tank regularly. It is best to do this once a week.

2、 Cleaning of protective lenses: there will be some mirrors and focusing mirrors on the machine. The laser is reflected and focused by these lenses and then exits the laser head. The lens is easy to be stained with dust or other pollutants, resulting in laser wear or lens damage. Therefore, clean the lenses every day. At the same time, please note:

1. Wipe the lens gently to avoid damaging the surface coating

2. The wiping process shall be handled with care to prevent falling;

3. When installing the focusing lens, make sure that the concave side is downward.

3、 Guide rail cleaning: as one of the core parts of the equipment, the guide rail and linear axis are used to support the guide rail. In order to ensure that the machine has higher processing accuracy, its guide rails and straight lines are required to have higher guidance accuracy and good motion stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing of parts. These soot will deposit on the surface of guide rail and linear shaft for a long time, which will greatly affect the processing accuracy of equipment, and will form corrosion points on the surface of linear shaft. The slideway will shorten the service life of the equipment. Therefore, clean the machine rails every half month. Turn off the machine before cleaning.

4、 Tighten the 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 the mechanical movement. Therefore, please observe the transmission components during operation. Operation of the machine. There is no abnormal sound or phenomenon. If problems are found, they should be cured 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 firmness shall be about one month after the equipment is used.

Fifth, optical path inspection: the optical path system of the machine is completed by reflection of the reflector and focusing of the focusing mirror. The focusing mirror has no offset problem in the optical path, but the three mirrors are fixed and offset by mechanical parts. Generally, although there is no offset under normal conditions, the user is recommended to check whether the optical path is normal before each operation.

Daily maintenance of laser cutting machine

1. Every other week, check the lubrication of X-axis guide rails and screws, Y-axis guide rails and screws, Z-axis guide rails and screws, maintain the lubrication of each moving part, and extend the service life of X-axis, Y-axis, Z-axis guide rails and steel wire rods. According to the workshop environment, irregularly check the contamination of the surface of the reflector and focus lens (at least once a month), and clean the optical lens in time to ensure its service life.

2. Clean the debris at the exhaust port regularly to ensure ventilation. influence.

3. Regularly check the filter in the gas circuit, and timely remove the water and debris accumulated in the filter.

4. Regularly check whether the screws of travel switch bracket and striker bracket are loose.

5. Clean the dust on the filter screen of the ventilation fan of the electrical control cabinet in time to ensure good ventilation and facilitate the heat dissipation of the internal electrical components.

6. Clean the bed surface, and timely clean the debris in the slide protective skin to avoid damaging the slide and extending the service life of the slide

7. After the machine tool is installed and used for a period of time, the level of the machine tool should be readjusted to ensure the cutting accuracy of the machine tool.
