Experienced laser engraving machine operators all know that after a long time of work, its reflector will be polluted by the soot generated during processing, which will greatly reduce the reflectivity and affect the laser output. At this time, we need to maintain the reflector of the laser engraving machine to ensure the output of the laser and the effect of the engraving machine, and to extend the service life of the equipment. Then, what should be paid attention to in the maintenance of the mirror of the laser engraving machine?
Laser engraving machine
The mirror should be cleaned with a special lens cleaning solution and carefully wiped with absorbent cotton. Try to avoid scratching the mirror with sharp objects. The workpiece on the lower surface of the focusing lens of the focusing lens can also be contaminated with volatility. When it is polluted, it will also greatly affect the laser output. Pay attention to smoke treatment and air blowing protection to avoid contamination of the focusing lens. If the contamination is carefully cleaned, the following methods can be taken:
1. Remove the charging pipe, pressure ring and protective sleeve, and carefully take out the focusing lens.
2. Use a hair dryer to blow away dust from the surface of the focusing lens.
3. Use tweezers to carefully dip the clamped cotton ball into alcohol or special lens cleaner and gently wipe it in one direction from inside to outside, once each, until the dirt is removed, so replace the cotton ball.
However, we should note that during the wiping process of the mirror, do not rub it back and forth, and ensure that the mirror can not be scratched by sharp objects. The surface of the mirror is coated with anti reflection coating, and the damage of the film will greatly affect the laser energy output and carving effect.
