Nowadays, laser cutting machine equipment has the advantages of short processing cycle, high quality of workpiece, and has a good application in many manufacturing industries. Due to the emerging technology, when users use the equipment for workpiece processing, it is inevitable that due to lack of understanding of the equipment, the machined workpiece surface has burrs, which greatly reduces the overall operation.
When many enterprises use laser cutting machines to cut, they find that there are many burrs and the quality of the workpiece is not ideal, so they doubt the quality of this cutting machine. Is that really the reason? Not necessarily. In most cases, the burr is not caused by the quality problem of the laser cutting machine itself, but by the wrong operation mode of the operator or the improper maintenance of the cutting machine.
To know that burr is actually the residual particles on the surface of metal materials when the laser cutting machine is processing, it is through the high energy generated by the laser beam irradiating the workpiece surface to make the workpiece surface evaporate rapidly, and then through the auxiliary gas to blow off the slag on the workpiece surface to achieve the purpose of cutting. The auxiliary gas is one of the main reasons for the burr on the workpiece surface.
Generally speaking, every laser cutting machine must be equipped with auxiliary gas. If the auxiliary gas is not used, after the slag is cooled, it will form a burr attached to the cutting surface of the workpiece. However, the selection of auxiliary gas is also particular. Users should choose a gas supplier with better quality when purchasing auxiliary gas, and the purity of gas is also very important.
In addition to the selection of auxiliary gas, we should also pay attention to the problem of equipment setting. When customers purchase laser cutting machines, they must have professional operators to debug the equipment. Adjust the cutting parameters to the best, including air pressure, flow focal length, and cutting speed, which need to be adjusted many times, because these can affect whether the workpiece surface will produce burrs.
In most cases, there is a burr on the surface of the workpiece, which is often caused by the improper use of the laser cutting machine equipment itself.
