Cutting accuracy is the key factor to judge the quality of fiber laser cutting machine. This paper will analyze four factors that affect the cutting accuracy of fiber laser cutting machine.

1、 The size of laser condensation of the laser generator: if the light spot is small after aggregation, the cutting accuracy is high, and if the gap after cutting is small. It shows that the fiber laser cutting machine has high precision and good quality. But the laser beam is conical, so the slit cut out is also conical. Under this condition, the greater the thickness of the workpiece, the lower the accuracy will be, so the larger the slit.

2、 Accuracy of workbench: if the accuracy of the workbench of the fiber laser cutting machine is very high, the cutting accuracy will also be increased. Therefore, the accuracy of the worktable is also an important factor to measure the accuracy of the laser generator.

3、 The laser beam is condensed into a cone: when the fiber laser cutter is cutting, the laser beam is downward in a cone. At this time, if the thickness of the cutting workpiece is large, the cutting accuracy will decline, and the cut gap will be large.

4、 Different cutting materials will also affect the accuracy of the fiber laser cutting machine. In the same case, the precision of cutting stainless steel and aluminum by optical fiber laser cutting machine will be different, and the cutting precision of stainless steel will be higher, and the cutting surface will be smoother.

In addition, when selecting the fiber laser cutting machine, in addition to the above points, we should also pay attention to the after-sales service of the manufacturer.
