4x8 aluminum sheet is the most welcomed size in aluminum sheet processing, cutting is often encountered in alloy processing. One of the problems is whether the aluminum sheet can be cut by laser? The answer is yes. A few years ago, the laser cutting machine was able to cut aluminum sheet. At that time, workers used ink to apply ink to the aluminum sheet (it is said that because the aluminum sheet have high reflectance, they are afraid of reflecting the laser). During cutting, the laser parameters are very difficult to adjust. At that time, only aluminum sheet with a thickness of 1 mm could be cut. After accumulating experience, the cut of the aluminum sheet is also very smooth and there is no dross.
Is the cut surface of laser cut 4x8 aluminum sheet as smooth as cutting other materials? The cut of the aluminum sheet is also smooth. The aluminum sheet 4x8 is only a highly reflective material and requires a large laser generator. The cutting gas is the same as other materials. It is cut with nitrogen and will not cause the surface to be uneven. The aluminum sheet uses laser cutting have features of:
1, The cutting seam is fine: the cutting seam of laser cutting aluminum sheet is generally 0.1mm-0.2mm
2, Smooth cutting surface: The cutting surface of laser cut aluminum sheet has no burrs and no slag.
3, Small thermal deformation: The laser cutting of laser processing is thin, fast, and concentrated in energy, so the heat transferred to the material to be cut is small, and the deformation of the material is also very small.
4, Material saving: laser processing adopts computer programming. The laser equipment can cut aluminum sheet processing parts of different shapes, improve the material utilization rate of aluminum sheet, and save a lot of material cost.
5, The thickness of the 4x8 aluminum sheet that can be cut mainly depends on the power of the laser generator. Generally, the thickness of 6000W can be cut to 16mm, and the thickness of 4500W can be cut to 12mm.
