Laser cutting is a very wide range of processing methods in laser processing. It is a particularly important application technology in laser processing industry. Laser cutting has been widely used in automobile, aviation, chemical and other industrial sectors.
The principle of laser cutting is to release the energy of the laser beam to the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. Cutting accuracy is an important part of measuring the effect of laser cutting machine processing, but the laser cutting accuracy is not entirely dependent on the device itself, but by a number of factors. Among them, the impact of laser cutting precision of several important factors:
1, the laser beam through the focus of the spot after the spot: the laser beam after the accumulation of the smaller spot, laser cutting the higher the precision, especially the smaller slits, the smallest spot up to 0.01mm.
2, the positioning accuracy of the table determines the repetition of laser cutting accuracy, the higher the accuracy of the table, the higher the accuracy of cutting.
3, the greater the thickness of the workpiece, the lower the accuracy, the greater the gap. As the laser beam is tapered, the slit is also tapered, the thickness of 0.3MM material than the 2MM of the small cut.
4, the workpiece material on the laser cutting accuracy have a certain impact. In the same case, the cutting accuracy of different materials is also slightly different, even if the same material, if the composition of different materials, cutting accuracy will be different.
