A few years ago, sheet metal laser cutting machines could cut aluminium sheets, but at that time they could only cut 1 mm thick sheets. Now more than that, depending on the power of the laser generator, the thickest can be cut, but it is not recommended to cut extreme thicknesses of aluminium sheets for long periods of time.
The ability of the sheet metal laser cutting machine to cut aluminium plates depends on the power of the laser machine, generally the thickest can be cut, but the processing costs are higher. This is a highly reflective material.
Laser cutting is the use of focused high power density laser beam irradiation workpiece, so that the irradiated material quickly melted, vaporized, ablated or reached the ignition point, while blowing away the melted material with the help of high-speed airflow with the beam coaxially, to achieve the cutting of the workpiece.
Reflective, if you want to cut the aluminum plate, you need to add a device on the laser head.
A few years ago, sheet metal laser cutting machines could cut aluminium sheets. At that time, workers coated the aluminium plate with ink (supposedly because of its high reflection coefficient and fear of reflecting the laser). During the cutting process, the parameters of the laser varied considerably. Nice tone of voice. At that time, only aluminium sheets with a thickness of 1 mm could be cut. After gaining experience, the cut of the aluminium sheet was also smooth and free of slag.
Laser sheet metal light cutting aluminum plate also depends on the power of the laser generator, the thickest can cut, but also cut, but the processing costs are high, because it is a highly reflective material, laser cutting using a focused high power density laser beam irradiation workpiece, so that the irradiated material quickly melted, vaporized, ablated or reached the ignition point, while being coaxial with the beam of high-speed airflow blown away molten material, so as to achieve the workpiece cutting.
Is the cutting surface of a light-cut aluminium sheet as smooth as cutting other materials?
The cut of aluminium sheet is also smooth. Aluminium sheet is only a highly reflective material and requires a large laser generator. The cutting gas is cut with nitrogen just like any other material and does not cause uneven surfaces.
Features of cutting aluminium sheets with a sheet metal laser cutting machine.
1，Thin cutting slit: the cutting slit of laser cut aluminium sheet is generally 0,1mm-0,2mm
2, smooth cutting surface: laser cutting aluminum cutting surface without burrs, no hanging slag.
3, small thermal deformation: laser processing slit thin, fast, concentrated energy, so the heat transferred to the cut material is very small, the deformation of the material is also very small.
4, save material: laser processing using computer programming, laser equipment can cut out different shapes of aluminium sheet processing parts, improve the material utilization rate of aluminium sheet, save a lot of material costs. Beam laser
5, can cut the thickness of the aluminium plate depends mainly on the power of the laser generator. Generally the thickest aluminium plate can be cut cutting.
Sheet metal laser cutting machine cutting aluminium plate precautions.
Aluminium sheet is a highly reflective material and can cause great damage to the laser, so use as little as possible. It is recommended that aluminium plates below 6mm can be processed by CNC punching, and aluminium plates above 6mm can be processed by water cutting.
