Common fault phenomena and possible causes

CO2 laser cutting machines often encounter various failures in the process of cutting various materials. These failures may lead to reduced cutting quality, reduced production efficiency, and even affect the life and safety of the equipment. The following will introduce common fault phenomena and possible causes of CO2 laser cutting machines:

Reduced cutting quality

Fault phenomenon:

Burnt or burred edges appear
The cutting surface is uneven, corrugated, or uneven

Possible reasons:

The optical lens is dirty or worn: The optical lens is a key component that focuses the laser beam onto the workpiece surface. When the lens surface is subject to dust, oil, or wear, it will affect the focusing effect of the laser beam, resulting in a decrease in cutting quality.
Cutting speed is too fast or too slow: The cutting speed is related to the type and thickness of the material. If the speed is too fast, the material may not be completely melted, and if the speed is too slow, the quality of the cutting surface will be reduced.
Inaccurate laser beam focus: If the laser beam focus is inaccurate, the energy density at the cutting point is uneven, which will cause the cutting surface to be uneven or the edges to be burnt.

Unstable cutting speed

Fault phenomenon:

Sudden changes or fluctuations in cutting speed
The cutting lines are discontinuous or have jumps

Possible reasons:

Unstable power supply: CO2 laser cutting machines have high requirements for stable power supply. Power supply fluctuations or voltage instability will directly affect the laser power output, resulting in unstable cutting speed.
Damage to optical components: Optical components include mirrors and lenses. If any of them is damaged or stained, it will affect the transmission and focusing effect of the laser beam, resulting in unstable cutting speed.
Control system failure: Control system failure may result in inaccurate or failed cutting speed adjustment, requiring recalibration or replacement of faulty parts.

Cutting head parts damaged

Fault phenomenon:

Cutting head parts are severely worn
Lenses cracked or falling off

Possible reasons:

Wear of cutting head components: Cutting head components will be worn under long-term high-intensity work, especially the cutting gas nozzle and protective pad. Severe wear will affect cutting quality and efficiency.
The lens is broken or detached: The lens is an important part of the optical lens. Once it is damaged or detached, it will directly affect the transmission and focusing effect of the laser beam, resulting in a decrease in cutting quality.

Gas supply issues

Fault phenomenon:

Reduced cutting quality
Cutting speed is unstable

Possible reasons:

Unstable gas flow: During the cutting process, the gas flow injected by the gas nozzle needs to remain stable, otherwise the cutting quality will be affected.
Abnormal gas pressure: Abnormal pressure in the gas supply system will cause unstable gas flow and affect cutting quality and speed.
The above listed are only some of the common faults of CO2 laser cutting machines. For operators, timely identification and troubleshooting are the keys to ensuring stable equipment operation and production efficiency. Therefore, understanding the possible causes of failure and the corresponding solutions is crucial to maintaining the normal operation of the CO2 laser cutting machine.
