The price of laser cutting machines is not low, ranging from hundreds of thousands to millions. Therefore, extending the service life of the laser cutting machine as much as possible can better save production costs and win greater benefits. It can be seen that the daily maintenance and repair of laser cutting machines is very important. The following is mainly explained from several aspects:
Daily maintenance of laser cutting machine
1、 Replacement of circulating water and cleaning of water tank:
Before operating the machine, make sure that the laser tube is filled with circulating water. The quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, it is necessary to regularly replace the circulating water and clean the water tank. This is best done once a week.
2、 Cleaning of protective lenses:
There will be some mirrors and focus lenses on the machine. Laser light is reflected through these lenses, focused, and emitted from the laser hair. The lens is easily stained with dust or other contaminants, resulting in laser loss or lens damage. So clean the lenses every day. During cleaning, attention should be paid to: 1. The lens should be gently wiped to avoid damaging the surface coating; 2. The wiping process should be handled gently to prevent falling; 3. When installing the focus lens, be sure to keep the concave surface downward.
3、 Guide rail cleaning:
As one of the core components of the equipment, the guide rail and linear shaft function as a guide and support. In order to ensure a high machining accuracy of the machine, its guide rails and straight lines are required to have high guiding accuracy and good motion stability. During the operation of the equipment, due to the large amount of corrosive dust and smoke generated during the processing of the processed parts, these smoke and dust have been deposited on the surface of the guide rail and linear shaft for a long time, which has a significant impact on the processing accuracy of the equipment, and can form corrosion spots on the surface of the guide rail linear shaft, shortening the service life of the equipment. Therefore, clean the machine guide rail every half a month. Shut down the machine before cleaning.
4、 Fastening of screws and couplings:
The equipment can be hardened for the first time after being used for about a month. After the motion system has been operating for a period of time, the screws and couplings at the motion joints may become loose, affecting the smoothness of mechanical movement. Therefore, during machine operation, it is necessary to observe whether there are abnormal noises or abnormal phenomena in the transmission components, and if any problems are found, it is necessary to strengthen and maintain them in a timely manner. At the same time, the machine should use tools to tighten the screws one by one over time.
5、 Inspection of optical path:
The optical path system of the machine is completed by the reflection of the mirror and the focusing of the focusing mirror. In the optical path, the focusing mirror does not have a deviation problem, but the three mirrors are fixed by mechanical parts, with a high possibility of deviation. It is recommended to check whether the optical path is normal before each operation.
1. Every other week, it is necessary to check the lubrication of the X-axis guide rail and lead screw, Y-axis guide rail and lead screw, Z-axis guide rail and lead screw, maintain the lubrication of all moving parts, and extend the service life of the X-axis, Y-axis, Z-axis guide rail and lead screw. At least once a month) Check the surface contamination of the mirror and focus lens, and timely clean the optical lens to ensure its service life
2. Regularly clean the debris at the exhaust port to ensure the ventilation effect.
3. Regularly inspect the filter in the gas path and timely remove water and debris from the filter.
4. Regularly check whether the screws of the travel switch bracket and the impact block bracket are loose.
5. Clean the dust on the filter screen of the electric control cabinet ventilator in a timely manner to ensure good ventilation and facilitate heat dissipation of internal electrical components. 6. Clean the debris in the protective leather cavity of the guide rail in time to avoid damaging the guide rail, thereby extending the service life of the guide rail.
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.
