The accuracy of laser cutting machine directly affects cutting quality. If there is a deviation in accuracy, the workpiece is unqualified. So operators should learn several important factors affecting the accuracy of laser cutting.
Generally speaking, the smaller the focusing spot, the higher the accuracy of laser cutting. For example, When the slit is small enough, the minimum spot can reach 0.01mm. Besides, the workpiece of material also has a impact on laser cutting accuracy. Similarly, the cutting precision of different materials is also slightly different. Even if it is the same material, if the composition of the material is different, the cutting precision will be different.
So how to improve the accuracy under different conditions?
1. Control focus position. The smaller the depth of focus, the smaller the focussed diameter of the beam. So it is very important to control the position of the focus relative to the surface of the cutting material
2. Cutting and punching technique. In all but a few cases, any hot cutting technique requires a small hole in the plate.
3. Nozzle design and air flow control technology. When steel cutting, the oxygen and laser beam are shot through the nozzle to the cutting material, forming an airflow beam. So the sufficient oxygen makes the material sufficiently exothermic and there is also enough energy to eject the molten material.
