The precision of laser cutting machine directly affects the cutting quality. If there is deviation in accuracy, the workpiece is unqualified. Therefore, the operator should understand several important factors that affect the accuracy of laser cutting.
Generally speaking, the smaller the focus, the higher the accuracy of laser cutting. For example, when the slit is small enough, the minimum spot can reach 0.01 mm. In addition, the precision of laser cutting is also affected by the workpiece of materials. Similarly, the cutting accuracy of different materials is slightly different. Even if it is the same material, if the composition of the material is different, the cutting accuracy will also be different.
How to improve the accuracy under different conditions?
1. Control the focus position. The smaller the focusing depth is, the smaller the focusing diameter of the beam is. Therefore, the position of the control focus relative to the cutting material surface is very important
2. Cutting and stamping technology. Except for a few cases, in any case, any thermal cutting technology needs to leave a small hole in the plate.
3. Nozzle design and air flow control technology. When cutting steel, oxygen and laser beams will shoot at the cutting material through the nozzle, thus forming an air flow beam. Therefore, there is enough oxygen to make the material fully exothermic, and there is also enough energy to spray the molten material.
