Laser cutting is the laser beam emitted from the laser, through the optical system, focusing into a high power density laser beam. The laser beam is irradiated onto the surface of the workpiece so that the workpiece reaches the melting point or boiling point while the high pressure gas coaxial with the beam blows the molten or gasified metal. As the beam and the workpiece relative to the location of the movement, the final material to form a slit, so as to achieve the purpose of cutting.
Laser cutting is the use of invisible beam instead of the traditional mechanical knife, with high precision, fast cutting, not limited to cutting pattern restrictions, automatic layout saving materials, incision smooth, low processing costs, will gradually improve or replace the The traditional metal cutting process equipment. Laser cutting speed of the machine, the workpiece is not in contact with the workpiece, in the work will not cause the workpiece surface scratches; laser cutting speed, smooth incision, generally without follow-up processing; cutting heat affected area small, small deformation plate, 0.1mm ~ 0.3mm); no mechanical stress, no shear burrs; high precision, good reproducibility, no damage to the surface of the material; NC programming, can be processed any plane plan, you can large format full board cutting, Open mold, economical and time-saving.
Cutting accuracy is the first element to judge the quality of CNC laser cutting machine. Four factors that affect the cutting accuracy of CNC laser cutting machine:
1, the size of the laser generator laser condensation. After the collection, if the spot is very small, the cutting accuracy is very high, if the gap after cutting is also very small. It shows that the precision of laser cutting machine is very high, the quality is very high. But the laser beam emitted by the cone, so cut out the gap is also cone. Under such conditions, the greater the thickness of the workpiece, the accuracy will be lower, so the greater the gap.
2, the accuracy of the table. If the accuracy of the table is very high, then the accuracy of cutting will also increase. So the precision of the table is also a very important factor in measuring the accuracy of the laser generator.
3, the laser beam condensed into a cone. When cutting, the laser beam is tapered down, then if the thickness of the workpiece is very large cutting, cutting the accuracy will be reduced, then cut out the gap will be very large.
4, cutting the different materials, will also affect the accuracy of laser cutting machine. In the same circumstances, cutting stainless steel and cutting aluminum its accuracy will be very different, stainless steel cutting accuracy will be higher, and the surface will be smooth.
