Co2 Laser Engraving Machine Optical System ——Lens Cleaning and Optical Path Alignment

In the daily operation of a CO2 laser engraving machine, the stability of the optical system directly determines the engraving quality and equipment lifespan. As the core link in laser energy transmission, lens and optical path maintenance is particularly important. Jinan REZES CNC Equipment Co., Ltd. reminds users that regular lens cleaning and optical path alignment are key measures to ensure equipment accuracy and extend its lifespan.

Ⅰ. Lens Cleaning: Maintaining Light Transmittance and Preventing Energy Loss

Over long-term use, optical components such as focusing lenses and reflectors are prone to accumulation of dust, oil, or debris. These impurities can cause laser energy attenuation and even ablation of the lens surface. Operators are advised to regularly inspect the lens surface and gently wipe it with dust-free paper and a dedicated lens cleaning fluid. Avoid using rough cloths or corrosive liquids such as alcohol to prevent scratches or coating damage.

Ⅱ. Optical Path Alignment: Ensuring Accurate and Consistent Laser Beam Transmission

The optical path of a CO2 laser engraving machine consists of multiple sets of reflectors. If the lenses are misaligned or installed at an improper angle, the laser beam will not be accurately focused, affecting engraving accuracy. Optical path calibration should be performed regularly. By adjusting the reflector screw position, ensure that the laser beam is centered, vertical, and accurately focused on the work surface at each reflection point.

III. Maintenance Cycle and Operation Recommendations

1.Check the lens for dust and oil before starting the machine daily.

2.Perform a comprehensive optical path inspection weekly.

3.If you notice signs of thickening engraving lines or a decrease in power, immediately perform an optical system inspection.

Through scientific maintenance and meticulous operation, the CO2 laser engraving machine‘s optical system can maintain stable operation over the long term, delivering highly precise and consistent laser energy. Jinan REZES CNC Equipment Co., Ltd. recommends that users maintain standardized maintenance records to ensure continued efficient operation of the equipment.
