The application of optical fiber laser cutting machine in cross industry sheet metal processing is very common. However, in the process of sheet metal processing, the squeal and burr at the transition of the workpiece surface directly affect the quality of the workpiece. Some of them have adopted the deburring process in the production process of products, but they have not completely solved the problem of looking at burrs. So many users began to suspect that it was the quality of the laser cutting machine. In fact, this is not the case.

Burr of sheet metal processing workpiece

First of all, we need to understand how burrs are generated?

In fact, burr is the excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam illuminating the workpiece surface will vaporize and evaporate to achieve the purpose of cutting. But here is a device that we should pay attention to, namely, gas.

The gas is to blow off the slag on the workpiece surface after gasification of the workpiece irradiation surface. If the gas is not used, the slag will form burrs attached to the cutting surface after cooling. Therefore, the purity of the gas should be high. The purity of the gas is very important. Do not use the cylinder gas, because after twice filling, the purity is not good and the gas is wasted. In the process of sheet metal processing, if the equipment+gas+parameters are adjusted well, the workpiece will be free of burrs.

Another reason is the quality problem of the equipment itself, as well as the parameter setting factor. Therefore, when customers purchase laser cutting machines, they should let experienced operators debug the equipment. Therefore, it is necessary to adjust the cutting parameters as well as the air pressure flow focal length cutting speed and so on, which should be adjusted for many times. It is impossible to cut high-quality workpieces only by relying on the parameters provided by the machine. Therefore, it is recommended that after-sales service be an important inspection item when purchasing laser cutting machine equipment.

In addition, improper operation of silver, technical problems, and the quality of materials processed by the laser cutting machine during sheet metal processing may lead to burrs on the workpiece. If a material has burr, it can be qualitatively defective. The more burr, the lower the quality, which will leave problems for the subsequent inspection, assembly, performance and aesthetics of the product.

So, how to solve the problem of high burr in the process of sheet metal processing of laser cutting machine?

Generally speaking, the burr of laser cutting machine can be checked and solved from the following aspects:

1. The output power of the laser cutting machine is not enough.

Solution: Check whether the laser cutting machine works normally. If it is abnormal, timely repair and maintenance are required. If it is normal, check whether the output value is correct.

2. The upper and lower positions of the beam focus deviate.

Solution: Adjust the focus position according to its offset position.

3. The gas purity of the cutting machine is not enough.

Solution: Change the gas.

4. The wire cutting speed of the cutter is too slow.

Solution: Adjust the wire cutting speed in time.

5. The addition point of the laser beam of the cutting machine has shifted.

Solution: Conduct focus debugging and timely adjustment

6. The laser cutting machine is unstable due to too long operation time.

Solution: Turn off the machine and restart it and let it rest.

The laser cutting machine is a precise machine, and often a data error will cause the abnormal operation of its work, so it should be strict in the work to reduce errors.
