Maintenance of laser cutting machine lens (1)


The lens of the laser cutting machine is located in the lower part of the centering module and is easily polluted by smoke and dust. It is recommended to clean it once a day before starting work. First completely loosen the screws of the protective mirror drawer, pinch the two sides of the protective mirror box drawer with your thumb and index finger, slowly pull out the protective mirror box drawer, taking care not to lose the sealing rings on the upper and lower sides of the drawer, and then seal the drawer opening with adhesive paper. Prevent dust from contaminating the focusing lens. The protective lens is a flat lens, and the sealing ring and the protective lens are released by pressing the lens. When installing the lens, place the lens first, and then press the sealing ring. The collimating lens and the focusing lens are located inside the fiber cutting head, and the sequence of disassembly is recorded when disassembling, and the accuracy of reinstallation must be ensured.

1. Precautions for the use of lenses

Do not touch the focusing lens, protective lens, QBH head and other optical surfaces directly with your hands to prevent scratches or corrosion of the mirror surface. If there is oil or dust on the lens surface, it will seriously affect the use of the lens, and the lens should be cleaned in time. The surface of the optical lens is strictly prohibited to use water, detergent, etc. to clean. The surface of the lens is coated with a special film. If you use these to clean the lens, it will damage the surface of the lens. Do not place the lens in a dark and humid place, as this will cause the surface of the lens to age. When installing or replacing the reflector, focusing lens and protective lens, do not use too much pressure, otherwise it may cause the deformation of the lens and affect the quality of the beam.
