Cutting accuracy is the first factor to judge the quality of CNC laser cutting machine. Four major factors affecting the cutting accuracy of CNC laser cutting machine:
1. The size of laser condensation in laser generator. If the spot is very small after aggregation, then 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, and the quality is very high. But the laser beam is conical, so the slit is also conical. Under this condition, the greater the thickness of the workpiece, the lower the accuracy, so the larger the slit.
2. Precision of worktable. If the accuracy of the table is very high, the cutting accuracy will also be improved. Therefore, the accuracy of the worktable is also a very important factor to measure the accuracy of the laser generator.
3. Laser beams condense into cones. When cutting, the laser beam is tapered down. If the thickness of the cutting workpiece is very large, the cutting accuracy will be reduced, and the gap will be very large.
4. Different cutting materials will also affect the accuracy of laser cutting machine. In the same case, the accuracy of cutting stainless steel and aluminum will be very different, the cutting accuracy of stainless steel will be higher, and the cut surface will be smoother.
