Laser cutting accuracy is an important factor to measure the quality of a fiber laser cutting machine. The four major elements that affect the accuracy of laser cutting machines. Errors in processing dimensions are often encountered when using laser cutting machines for processing. This fault not only affects Increased production efficiency and increased production costs. In fact, the accuracy of metal laser cutting machine is not entirely determined by the equipment itself, but is composed of many factors.
1. The size of the laser condensation of the laser generator: if the light spot is very small after the aggregation, the cutting accuracy is very high, and the gap after cutting is also very small. It means that the precision of the laser cutting machine is very high and the quality is very high. But the beam emitted by the laser is tapered, so the slits cut out are also tapered. Under this condition, the greater the thickness of the workpiece, the lower the accuracy, and therefore the larger the kerf.
2. The accuracy of the workbench: If the accuracy of the workbench is very high, the cutting accuracy will also be improved. Therefore, the accuracy of the workbench is also a very important factor to measure the accuracy of the laser generator.
3. The laser beam is condensed into a cone: when cutting, the laser beam is downward in a cone. At this time, if the thickness of the workpiece to be cut is very large, the cutting accuracy will be reduced, and the cut out gap will be very large.
4. Different cutting materials: Even if it is the same material, if the composition of the material is different, the cutting accuracy will be different. Therefore, the workpiece material also has a certain influence on the laser cutting accuracy.
The metal laser cutting machine is realized by applying the high power density energy generated by the laser focusing. It adopts precision ball screw transmission mechanism and optimized numerical control system control, which can meet the processing of precision parts, and has stable dynamic performance and can work for a long time. Therefore, it has attracted much attention in metal cutting. The cutting accuracy of metal can affect the cutting process.
Since there is a problem of cutting accuracy, how can we ensure high-precision laser cutting?
Methods to improve cutting accuracy:
Focus position control technology. The smaller the focal depth of the focusing lens, the smaller the diameter of the focal spot, so it is very important to control the position of the focal point relative to the surface of the material being cut.
