The reasons for insufficient power of CO₂ laser marking machine may include the following points.
Laser aging: After prolonged use, the laser will experience aging, leading to a decrease in power.
Improper adjustment of the optical path: The adjustment of the optical path of the CO₂ laser marking machine is very important. If not adjusted properly, it can lead to a decrease in laser power.
Lens contamination: The lenses of CO₂ laser marking machines are easily contaminated by dust, oil, and other pollutants, leading to a decrease in laser power.
Laser tube damage: The laser tube is one of the core components of the laser marking machine. If the laser tube is damaged, it will cause a decrease in laser power.
Power supply voltage drop: causing a decrease in laser input power, which in turn affects the output power of the CO₂ laser marking machine.
The lens of the laser marking machine is stained and needs to be cleaned or replaced.
The CO₂ laser marking machine has inaccurate track fragments: it is necessary to adjust the laser, adjust the position of the beam expansion mirror, and direct the incoming light to the center of the beam mirror, the center of the light hole, and the center of the light hole.
The surface of the workpiece is not on the focal plane: it is necessary to adjust the surface of the workpiece to the focal point.
The position and direction analysis of the beam mirror of the CO₂ laser marking machine is inaccurate: the position of the beam expander needs to be adjusted.
Fast marking speed: Slowing down the marking speed appropriately can solve the problem of insufficient power.
The solution includes replacing the laser, adjusting the optical path, cleaning the lens, replacing the laser tube, adjusting the power supply voltage and power, cleaning or replacing contaminated lenses, adjusting the optical path and beam expander position, adjusting the workpiece surface to the focal point, and appropriately slowing down the marking speed.
