The price of laser cutting machine is not low, ranging from hundreds of thousands to millions. Therefore, as long as possible to extend the service life of the laser cutting machine can better save production costs and obtain greater benefits. It can be seen that the daily maintenance and maintenance of the laser cutting machine is very important. The following mainly explains from six aspects:
Circulating water replacement and water tank cleaning
Make sure that the laser tube is filled with circulating water before the machine works. The water 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.
Long-term use of the fan in the machine will cause a lot of solid dust to accumulate in the fan, causing the fan to produce a lot of noise, and it is not conducive to exhaust and deodorization. When the fan suction is insufficient and the smoke is not smooth, the fan must be cleaned.
There will be a collimator lens and a focusing lens on the machine. The laser is emitted from the laser head through these lenses. The lens is easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. So clean the lenses every day. At the same time of cleaning, pay attention to: 1. The lens should be gently wiped, and the surface coating should not be damaged; 2. The wiping process should be handled gently to prevent falling; 3. When installing the focusing lens, be sure to keep the concave surface down.
Cleaning of the guide rail
As one of the core components of the equipment, guide rails and linear shafts mainly play a guiding and supporting role. In order to ensure the high processing accuracy of the machine, the 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 will be deposited on the surface of the guide rail and linear shaft for a long time, which will have a great impact on the processing accuracy of the equipment, and will Corrosion points are formed on the surface of the linear axis of the guide rail, which shortens the service life of the equipment. Therefore, the machine guide rails are cleaned every half month. Turn off the machine before cleaning.
Fastening of screws and couplings
After the motion system has been working for a period of time, the screws and couplings at the motion connection will loosen, which will affect the smoothness of the mechanical motion. Therefore, during the operation of the machine, observe whether there are abnormal noises or abnormal phenomena in the transmission components, and find problems in time. Sturdy and maintained. At the same time, the machine should use tools to tighten the screws one by one after a period of time. The first firming should be about one month after the equipment is used.
Inspection of light path
The optical path system of the machine is completed by the double focusing of the collimator lens and the focusing lens. There is no offset problem of the focusing lens in the optical path, but the collimating lens is fixed by the mechanical part, and the possibility of offset is relatively large, although usually In this case, there will be no deviation, but it is recommended that the user check whether the optical path is normal before each work.
