When laser cutting metal workpieces, burr often occurs. The burr here refers to the excessive residue particles generated on the metal surface during laser cutting. Too many burrs will not only directly affect the quality of the workpiece, but also cause a lot of losses to enterprises and customers. How to solve this common problem when laser cutting?
Next, let’s analyze the specific problems:
According to the working principle of the laser cutting machine, we step by step analyze the causes of burrs and solutions. When the laser cutting machine is processing the workpiece, the laser beam shines on the workpiece surface for cutting, and the energy generated will vaporize the workpiece surface, so as to achieve the purpose of laser cutting.
In general, the success of laser cutting machine in metal processing depends on the parameter setting and gas purity. Inaccurate adjustment of laser cutting machine parameters will directly affect the accuracy of cutting; If the purity of the gas used is not enough, or the pressure is not enough, the workpiece cut will lead to unclean slag blowing, and eventually lead to burrs.
The specific troubleshooting methods for burrs caused by laser cutting are as follows:
1. The purity of auxiliary gas of the cutter is not enough. Solution: Improve the purity of auxiliary gas. Such as air replacement, oxygen, etc.
2. Check whether the laser focus position of the laser cutting machine is correct. Solution: Test the focus position and adjust it according to the offset of the focus.
3. Equipment instability caused by long-time operation of laser cutting machine. Solution: Shut down and restart the device.
4. The linear cutting speed of the laser cutting machine is too slow. Solution: Adjust and improve the wire cutting speed in time.
5. The output power of the laser cutting machine is not enough. Solution: Check whether the laser works normally. If so, observe whether the output value of the laser control button is correct. If it is abnormal, we need to repair and maintain it in time. If it is normal, check whether the output numerical analysis is correct.
In general, when laser cutting metal workpieces, more or less the burrs will appear on the cut sheets. When the burrs appear on the cutting, we should analyze and check them one by one according to the specific problems. I hope this article can help you.
