How to Reduce the Error Caused by Laser Cutting of Aluminum Plate?

Mar. 19, 2020

When workers are laser cutting aluminum plates, some skilled old workers are very skilled and they will strive to reduce the errors to a small amount. But how do they do it in specific aspects? Generally, the slit width of laser cutting is about 0.5 mm. So how do we reduce errors during the cutting process? The following Al Alloy Sheet Laser Cutting Exporter will explain for you;

First, when we are using Al Alloy Sheet Laser Cutting to operate, we must ensure that the error of the shearing machine can be controlled. Of course, it is impossible to have no error when we operate, but we must ensure this error. It is in the corresponding range. As for the specific width, this specific width is not a fixed value. Generally speaking, it is mainly related to the thickness, properties, laser power and jet pressure of the material being cut. Control can be as high as 0.01 mm.

2. After laser cutting of aluminum plate, aluminum plate generally has many characteristics. Cutting the aluminum plate first can save material. Because laser cutting of aluminum plate is set by computer programming, the laser equipment can nest different shapes of aluminum plate processed parts without material waste, which can improve The utilization rate of aluminum plate material reduces the material cost. Secondly, the aluminum plate processed by laser has a narrow slit, fast speed and more concentrated energy. This avoids the small amount of heat transferred to the cutting aluminum plate and the easy deformation of the aluminum plate.

Third, the power of the laser generator will also affect the performance of laser cutting of aluminum plates. Usually 4500W power can cut to a thickness of 12mm, while 6000W power can cut to a thickness of 16mm, but the processing cost is relatively high. Because aluminum plate is a highly reflective metal, laser cutting needs to irradiate the workpiece with a focused high power density laser beam, so that the irradiated material can quickly reach the ignition point, vaporize, ablate and melt, and want to cut the workpiece On, you should also remove the molten material by means of a high-speed gas stream that can be coaxial with the beam.

Fourth, the laser cutting speed is fast, the cut is smooth and flat, generally no subsequent processing is required; resulting in a small heat-affected zone of laser cutting of aluminum plate, small deformation of the plate, narrow slit (0.1mm ~ 0.3mm); no mechanical stress in the cut, no shear burr High processing accuracy, good repeatability, without damaging the surface of the material; NC programming, can process any floor plan, can cut the whole board with large format, no need to open the mold, economic and time saving.
