Several key technologies of laser cutting machines are comprehensive technologies integrating light, machinery and electricity. In laser cutting machines, the parameters of the laser beam, the performance and accuracy of the machine and CNC system all directly affect the efficiency and quality of laser cutting.

Cutting accuracy is the first factor to judge the quality of CNC laser cutting machine. 

Four major factors that affect the cutting accuracy of CNC laser cutting machines:

1. The size of the laser condenser of the laser generator. If the light spot is very small after focusing, the cutting accuracy will be very high, and if the gap after cutting is also very small. This shows 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 cone-shaped, so the gap cut out is also cone-shaped. Under this condition, the greater the thickness of the workpiece, the lower the accuracy will be, so the slit will be larger.

2. The accuracy of the workbench. If the precision of the workbench is very high, the precision of cutting will also increase. Therefore, the accuracy of the workbench is also a very important factor in measuring the accuracy of the laser generator.

3. The laser beam is condensed into a cone shape. When cutting, the laser beam is conical downward. If the thickness of the cut workpiece is very large, the cutting accuracy 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 cut surface will be smoother.

Generally speaking, laser cutting quality can be measured by the following 6 standards.

1. Cutting surface roughness Rz

2. Dimensions of slag hanging in the incision

3. Trim verticality and slope u

4. Cutting edge fillet size r

5. Stripe drag amount n

6. Flatness F
