Symptom: Material cannot be cut through, and there is adhesion at the bottom.

Causes of Incomplete Cutting with Metal Laser Cutting Machine:

Insufficient Laser Power: Laser tube aging, power setting too low.

Inaccurate Focus: Incorrect focusing lens installation or improper focus adjustment.

Excessive Cutting Speed: Speed and power mismatch.

Optical Path Misalignment: Laser beam does not pass completely through the center of the focusing lens, resulting in energy loss.

Auxiliary Gas Problem (for Metal Cutting): Insufficient gas pressure or incorrect gas type.

Laser Cutting Machine Repair Solutions:

Check Power Settings: Increase the power appropriately in the software, or test the actual output power of the laser tube; replace the laser tube if necessary.

Recalibrate Focus: Use a focusing ruler to accurately measure and adjust the cutting head height.

Reduce Cutting Speed: Adjust the speed parameters in the software to ensure power and speed match.

Correct the Optical Path: Starting from the laser tube exit, check each reflector step by step to ensure the beam center is aligned.

Check the air supply: Ensure there is a sufficient air supply, adjust the air pressure to the recommended value, and check for air leaks in the air tube.
