Fiber laser cutting machine is a laser cutting machine that uses fiber laser generator as light source. It is a new type of fiber laser developed internationally that outputs high energy density laser beam and focuses on the surface of the workpiece, so that the area on the workpiece irradiated by the ultra-fine focal spot is instantly melted and vaporized, and the spot irradiation position is moved by the CNC mechanical system to achieve automatic cutting, with fast speed and high precision.
The size of the laser condensation of the laser generator: if the spot is smaller after focusing, the cutting accuracy is higher, and if the gap after cutting is also smaller. It means that the fiber laser cutting machine has high precision and good quality. However, the beam emitted by the laser is conical, so the cut gap is also conical. Under this condition, the thicker the workpiece, the lower the precision will be, so the larger the cut seam will be.
The accuracy of the fiber laser cutting machine table: If the accuracy of the fiber laser cutting machine table is very high, the cutting accuracy will also be improved. Therefore, the accuracy of the table is also an important factor in measuring the accuracy of the laser generator.
The laser beam condenses into a cone: When the fiber laser cutting machine cuts, the laser beam is downward in a cone. At this time, if the thickness of the workpiece is large, the cutting accuracy will decrease, and the cut gap will be larger.
Different cutting materials: It will also affect the accuracy of the fiber laser cutting machine. Under the same circumstances, the accuracy of the fiber laser cutting machine for cutting stainless steel and cutting aluminum will be different. The cutting accuracy of stainless steel will be higher, and the cut surface will be smoother.
