In the process of fiber laser cutting, sometimes irregular parts such as sharp corners and burrs at the transition of the workpiece material surface are burrs. Burrs directly and economically affect the dimensional calculation accuracy, shape and position control accuracy requirements, and some surface roughness of the workpiece to be machined. When the laser cutting machine is processing, the high surface quality generated by the laser beam irradiation can rapidly vaporize and evaporate the surface, so as to achieve the purpose of cutting. There are two main causes of glitches:
First, the auxiliary gas is vaporized on the irradiated workpiece surface, and then the slag on the workpiece surface is blown off. If no assist gas is used, the slag will form burrs that adhere to the cut surface after cooling. Equipment itself, parameter setting factors, daily use skills. Therefore, after customers buy a new fiber laser cutting machine, they must go through professional training before they can start using it.
Fiber laser cutters used in the deburring process:
1. The gas purity should be high, try not to use gas cylinders, because after two fillings, the purity is not good and the gas is wasted. For example, when laser cutting stainless steel, it is recommended to use nitrogen as an auxiliary gas, which is a flame retardant gas. In laser processing, nitrogen not only prevents the explosion point phenomenon of cutting, but also does not oxidize instantaneously after heating, and the cutting end surface is smooth and bright. The auxiliary gas should be adjusted to a pressure of 12-15 kg. Nitrogen at this pressure does not completely prevent combustion and can also be quickly blown away from waste impurities to remove burrs.
2. Find a professional operation manager to debug the parameters of the metal laser cutting machine, and then you can successfully complete the cutting technology operation of a fiber laser cutting machine. Some relevant parameters of the laser cutting machine will also affect the appearance of the slag, which can lead to burrs in the fiber laser cutting machine in our country, so our cutting parameters should be adjusted to the best. The gas parameters of the equipment are adjusted to the best, and the cut workpiece has no burrs, so that the cutting of the fiber laser cutting machine can be more high-quality. Check whether the laser cutting machine achieves normal development work. If it is not normal, the company needs to repair and maintain it in time. If it is not normal, check whether the result output value is selected correctly.
