（Manufacturer of spherical lens）After the machine works for a period of time, a layer of ash will stick on the surface of the lens due to the working environment, so as to reduce the reflectivity of the reflecting lens and the transmittance of the lens, and finally affect the working power of the laser. At this time, use a cotton wool dipped in alcohol to carefully rotate along the center of the lens to the edge. The lens should be gently wiped to avoid damaging the surface coating; the lens should be handled with care to prevent falling; the concave surface should be kept downward when installing the focusing lens. In addition, the use times of ultra-high speed perforation should be reduced as much as possible, and the service life of focusing lens can be prolonged by using conventional perforation.
（Manufacturer of spherical lens）During the operation of the equipment, the operator shall observe the working condition of the equipment at any time. In case of any abnormal condition, all power supply shall be cut off immediately, and the fault shall be eliminated or reported to the supervisor in time, and corresponding measures shall be taken actively. The usage of the machine shall be counted regularly, and each part of the laser cutting machine shall be recorded regularly. If the effect is not good, it shall be replaced in time to prevent the trouble
（Manufacturer of spherical lens）The environment of the workshop should be kept dry and well ventilated. The ambient temperature should be between 4 ℃ and 33 ℃. Attention should be paid to prevent condensation of equipment in summer and antifreeze of laser equipment in winter.
（Manufacturer of spherical lens）The equipment shall be far away from the electrical equipment sensitive to electromagnetic interference to prevent the equipment from long-term electromagnetic interference. Keep away from the sudden interference of large power and strong vibration equipment, which sometimes causes machine failure. Although it is rare, it should be avoided as far as possible. Therefore, such as large electric welding machine, huge electric mixer and large power transmission and transformation equipment should be far away from. Strong vibration equipment is more self-evident, such as forging press, the vibration caused by the short distance motor vehicle walking, etc. the obvious shaking of the ground is very unfavorable to the accurate carving.
（Manufacturer of spherical lens）The long-term cutting process of the equipment will produce dust, fine dust will enter into the equipment through the dust cover, thus attached to the rail rack, long-term accumulation will increase the wear of the rail rack. Rack guide rail is a relatively precise accessory. A large amount of dust has been deposited on the surface of guide rail and linear axis 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 linear axis of guide rail, thus shortening the service life of the equipment. Therefore, in order to ensure the normal and stable operation of the equipment and ensure the processing quality of the products, it is necessary to do a good job in the daily maintenance of the guide rail and linear shaft, and do dust removal and cleaning regularly. After cleaning the dust, grease the rack and lubricate the guide rail with lubricating oil. The bearings should also be regularly oiled, so as to maintain the drive flexibility, machining accuracy and extend the service life of the machine tool.
