When using a laser cutting machine, you may sometimes encounter situations where the cut is incomplete, which can be quite frustrating. So, what exactly causes this problem? Here are the main reasons:
1.Laser Power Degradation: Like any equipment, the laser in a fiber laser cutting machine will gradually decrease in power after being used for a period of time. Once the power is reduced, the cutting ability will naturally weaken, eventually leading to incomplete cutting.
2.Material Thickness Exceeds Limit: Each laser cutting machine has a maximum thickness limit that it can cut. If the material being processed exceeds the equipment’s maximum cutting thickness, the cutting effect will be greatly reduced, or even completely unable to penetrate.
3.Optical Element Contamination: Optical elements in the laser cutting machine, such as focusing lenses and reflecting mirrors, are easily covered by dust, oil, and other contaminants due to long-term exposure to the working environment. These contaminants will absorb or reflect laser energy, reducing laser power and affecting the cutting effect. Regular maintenance of the laser cutting machine is crucial.
4.Equipment Debugging Issues: On-site debugging is critical to the cutting quality of a laser cutting machine. If the debugging is not in place, for example, if the focal point is not accurate, it may lead to incomplete cutting.
5.Excessive Cutting Speed: If the cutting speed is set too fast, the laser energy will not have enough time to completely penetrate the material, resulting in skipped cuts and incomplete cutting. Adjusting the speed of the laser cutting machine is vital for optimal results.
6.Insufficient Auxiliary Gas Pressure: In the laser cutting process, the main function of the auxiliary gas is to blow away the residue produced during cutting and keep the cutting surface clean. If the auxiliary gas pressure is insufficient, the residue cannot be removed in time, which will hinder the penetration of the laser beam, leading to incomplete cutting.
