How to cut metal sheets great quality with fiber laser cutter

How to cut great quality metal sheets with fiber laser cutter?Many clients have this questions.Today we will talk about the affecting factors the cutting quality with fiber laser cutting machine.

First, the laser output power and mode

How to cut great quality metal sheets with fiber laser cutter?The higher the output power of the laser, the better the quality of the cut on the same thickness of the board. The higher the fit of the laser cutting mode to the material, the better the quality of the cut.

Second, the material of the processed parts

How to cut great quality metal sheets with fiber laser cutter?The effect of fiber laser cutting machine on different materials is different. Different metal materials have different characteristics. The absorption of laser heat is also different. Common stainless steel, carbon steel and iron plates absorb heat quickly. The quality of the cut is also high, and the opposite highly reflective material (aluminum, copper) is more difficult to cut.

At the same time, the thickness of the workpiece and the smoothness of the surface also affect the quality of the cut.

The metal fiber laser cutting machine is suitable for cutting thin plates. The carbon steel under 12mm and the stainless steel below 6mm have obvious cutting effect, the best quality and the efficiency can be guarante. In addition, in general, the flatter the surface of the material, the better the quality of the cut.

Third, the choice of focus position

How to cut great quality metal sheets with fiber laser cutter?It is very important that the fiber laser cutting machine determines the corresponding position of the focus and the material surface before working, which is directly related to the quality of the cutting. The power at the focus is the highest, and most of the time the focus is at the surface of the cut material. When the focus is at the best position, the minimum cut, the highest efficiency, and the best cutting speed for optimal cutting. result.

Fourth, the processing speed of cutting

The influence of cutting speed on the quality is very direct. The speed of the fiber laser cutting machine is too fast. Which is easy to cause the material through. And the speed is too slow to cause the residual slag and the phenomenon of burning edge. Therefore, we need to adjust the parameters according to the actual thickness calculation of the workpiece to try to cut to achieve the best cutting speed.

Finally,Auxiliary gas pressure and type

The pressure of the auxiliary gas also has a certain influence on the cutting quality. When a laser cutting machine use to cut some metal sheets at high speed. A higher gas pressure is generally require to prevent the back side of the slit from being slag. If the thickness of the material increases or the speed of the cut decreases. Then the gas pressure of the assist gas should be lower. And in order to prevent oxidation of the cut edge, the appropriate gas pressure should also be adjusted.
