How to judge the cutting quality of laser cutting machine
Release Time:
2023-07-07 10:18
Cutting accuracy is the first factor to judge the quality of CNC laser cutting machine. Four factors that affect the cutting accuracy of CNC laser cutting machines:
1. The size of the laser condensation of the laser generator. If the light spot is very small after gathering, the cutting precision is very high, and if the gap after cutting is also very small. It shows that the precision of the laser cutting machine is very high, and the quality is very high. However, the beam emitted by the laser is cone-shaped, so the slits cut out are also cone-shaped. Under this condition, the greater the thickness of the workpiece, the lower the accuracy, so the larger the kerf.
2. The precision of the workbench. If the precision of the workbench is very high, the precision of cutting 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 shape. When cutting, the laser beam is conical downward. At this time, if the thickness of the cut workpiece is very large, the cutting precision will be reduced, and the cut gap will be very large.
4. Different cutting materials will also affect the accuracy of the laser cutting machine. Under the same circumstances, the precision of cutting stainless steel and cutting aluminum will be very different, the cutting precision of stainless steel will be higher, and the cutting surface will be smoother.
Generally speaking, the quality of laser cutting can be measured by the following 6 standards.
1. Cutting surface roughness Rz
2. The size of the slag hanging on the incision
3. Trimming verticality and inclination u
4. Cutting edge fillet size r
5. Streak drag amount n
6. Flatness F

What are the laser cutting machine processes?
During the laser gasification cutting process, the surface temperature of the material rises to the boiling point temperature so fast that it is enough to avoid melting caused by heat conduction, so part of the material is vaporized into steam and disappears, and part of the material is ejected from the bottom of the slit by the auxiliary gas The flow blows away. Very high laser powers are required in this case.

Laser cutting machine principle
Laser light is a kind of light, which, like other natural light, is produced by the transition of atoms (molecules or ions, etc.). But it is different from ordinary light in that the laser only relies on spontaneous radiation in the first very short time, and the subsequent process is completely determined by the excitation radiation, so the laser has a very pure color, almost no divergent directionality, and extremely high luminous intensity and high coherence.
