The laser cutting machine uses a high-energy-density laser beam to irradiate the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the auxiliary gas blows away the molten metal material, and finally makes the material form a slit to achieve the purpose of cutting. The cutting quality of the laser cutting machine is the concern of every customer. If you want to cut satisfactory samples, you must use the laser cutting machine scientifically. Let me introduce the method to achieve high-quality cutting.
First，the cutting surface is smooth, with few lines and no brittle fracture. When the fiber laser cutting machine is cutting, the cutting marks will be displayed after the laser beam deviates. Slowing down the speed slightly at the end of the cut will eliminate the formation of streaks.
Second, the size of the slit width. The width of the slit is related to the thickness of the cutting plate and the size of the nozzle. In general, if the slit is narrow for cutting a thin plate, the selected nozzle is small. Similarly, when cutting thick plates, more air injection is required, so the nozzle is also large, and the cutting seam will be correspondingly wider. Therefore, it is necessary to find a suitable type of nozzle to cut a good product.
Third， the verticality of cutting is good, and the heat-affected area is small. The perpendicularity of the cutting edge is also particularly important. As the laser beam diverges away from the focal point, the cut widens towards the top or bottom depending on the position of the focal point. The more vertical the edge, the better the quality of the cut.
Although the operation of laser cutting equipment is relatively simple, it must be taken seriously during cutting. Only by correctly selecting the focus position and using the laser cutting machine scientifically and correctly can high-quality workpieces be cut.
