1. The thickness of cutting material exceeds the standard. Generally, the thickness of the plate cut by the metal laser cutting machine is less than 12. The thinner the plate, the easier it is to cut, and the better the quality. If the plate is too thick, the laser cutting machine is difficult to cut. Under the condition of ensuring cutting, the processing accuracy will have errors, so the thickness factor of the plate should be determined.

2. The laser output power is not up to standard. When the laser cutting machine is running and debugging, it is necessary to ensure that the output power of the laser reaches the standard. Generally, the higher the output power of the laser, the better the cutting quality on the same thickness of the plate.

3. Roughness of cutting plate. Generally, the smoother the surface of the cutting material, the better the cutting quality.

4. The focus position is inaccurate. If the focus of the laser cutting machine is not aligned, it will directly affect the cutting accuracy, so it should be calibrated and checked before operation.

5. Processing speed. The cutting speed of laser cutting machine directly affects the machining accuracy. Therefore, it is also necessary to match the cutting speed with the material well before operation.
