1. The lens is the key reason. If you want to check whether the lens is damaged or dirty, because this situation will cause the laser to scatter and cause the laser beam to become thicker, replacing or cleaning the lens is the only way.
2. The influence of cutting speed on the processing effect; the processing speed of the metal laser cutting machine is too fast, which will easily cause the workpiece to be cut through, or the speed is too slow to cause the residual cutting debris and the phenomenon of burning edges. It is necessary to adjust the parameters according to the actual thickness of the workpiece to test cutting to achieve the best cutting speed.
3. The effect of the characteristics of the cutting material on the processing; different metal materials have different characteristics and different laser absorption capabilities, so the cutting effect of metal laser cutting machines is also different, such as highly reflective materials (aluminum, copper). More difficult to cut. The other is that the surface of the processed material, film and other surface treatments are also more difficult to cut (depending on the situation).
4. The focus position selection of the laser cutting machine; it is very important to determine the corresponding position of the focus and the surface of the material, and it is directly related to the quality of the cutting. The power at the focal point is the highest, and most of the time the focal point is located on the surface of the cutting material or a little bit below the surface. When the focal point is at the best position, the slit is the smallest, the efficiency is the highest, and the cutting is best. The speed can obtain the best cutting result.
5. The laser tube is also a factor that cannot be ignored. Check the quality of the light spot of the laser tube. If there is a bright spot or the spot is not round or hollow, it is the support point of the laser tube and whether the direction is appropriate! The solution requires adjustment of the support, rotation direction, and replacement of the laser tube.
