Laser cutting machine is widely used in the manufacturing and processing industry, and its characteristics such as high efficiency, high quality finished products and flexible processing make it more and more favored by the industry. However, when using laser cutting machines, some customers find that the workpiece has more burrs. Many people mistakenly think that this is due to the quality of the laser cutting machine itself, but what is the fact?
In the process of workpiece processing, the parameters of the laser cutting machine and gas purity and other factors have an important impact on the processing quality. Only by using suitable and qualified gas, debugging the equipment and adjusting the parameters can we ensure that the workpiece cut out has no burrs. In fact, burrs are particles of residue left on the surface of metal materials. During processing, the laser cutting machine generates energy to vaporize the surface of the workpiece by shining the laser beam, so as to achieve the purpose of cutting. At the same time, auxiliary gases need to be used in the cutting process to quickly blow off the slag on the metal surface to ensure that the incision is smooth and burr free. Different materials need to choose different auxiliary gases for cutting, if the gas purity is not high or the pressure is not enough to reduce the airflow, it will lead to the slag can not be completely removed and form burrs.
Another reason for the appearance of burrs may be the setting of device parameters, such as the incorrect up and down position of the laser focus and so on. If the workpiece appears burrs, you can check from the following aspects:
① Whether the purity of the cutting gas is not enough, if it is not enough, high-quality cutting auxiliary gas can be replaced. If the laser focus position is correct, the focus position test can be done and adjusted according to the offset of the focus. ③ The output power of the laser is enough, you can check whether the laser is working normally, if it is normal, observe whether the output value of the laser control button is correct, and then adjust accordingly. ④ The wire cutting speed of the cutting machine is too slow, and the line speed needs to be increased during operation. ⑤ The running time is too long to cause the machine is unstable, you can shut down and restart, let the machine have a rest.
Through the efforts of MEN-LUCK company, we have developed a number of high-precision laser cutting machines, which can be widely used in laser cutting, drilling, grooving, marking and other micro-machining of various materials. System solutions can be customized according to customer needs. Welcome overseas friends in need to contact us.
