How to judge the laser cutting quality

Faced with a wide range of processing materials and flexible processing shapes, laser cutting equipment can better meet complex processing requirements, satisfying automotive, aerospace, healthcare, plastics, electrical and electronics, textiles with high speed, high precision and high quality. And other industry application needs. The judgment of the laser cutting effect can be mainly measured from the following aspects: (1) Roughness The edge of the cutting edge has more or less the texture left by the laser cutting, and the depth of the grain determines the roughness of the cutting surface. The lighter the grain, the lower the roughness and the smoother the surface. In general, the thinner the material thickness, the lower the surface roughness of the cut surface; the lower the surface roughness of the cut with oxygen or argon than the oxygen cut. (2) Verticality Since the laser cutting beam is focused by focusing and the beam is diverging, this results in inconsistent spot sizes at different depths of the material thickness during cutting (especially during thick plate cutting), resulting in a cutting surface. The surface of the sheet cannot be absolutely 90°, or the upper surface is wider or the lower surface is wider. In general, the thinner the material, the better the verticality; the better the beam quality, the better the verticality. In addition, it is also related to the relative position of the spot focus and the material thickness direction during the specific processing. (3) Glitch Excellent laser cutting, the laser cutting edge should be free of burrs, and the subsequent processing is required due to the presence of burrs. This is related to the process parameters of the specific process, the type of material and the quality of the beam. (4) Deformation amount Since the laser cutting is essentially thermal cutting, the sheet is inevitably deformed, and the excellent cutting should be as small as possible to reduce the adverse effects. Special attention should be paid to the cutting of thin plates. In general, the faster the cutting speed, the narrower the slit, the larger the gas flow rate, and the smaller the deformation amount.
