How to judge the quality of cutting machine

Cutting precision is the initial factor to decide the CNC laser cutting machine quality. The follow will list the four factors that affect the cutting accuracy of CNC laser cutting machine

1. The size of the laser condensation of the laser generator.

If the spot is very small after aggregation, the cutting accuracy 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. But when the beam from the laser is tapered,  the slit cut out is also tapered. Under this condition, the greater the thickness of the workpiece, the lower the accuracy, so the larger the slit

2. Accuracy of work table

 If the accuracy of the table is very high, the accuracy of the cutting will also be improved. Therefore, the accuracy of the table is also a very important factor in measuring the accuracy of the laser generator.

3. The laser beam condenses into a cone.

When cutting, the laser beam is conical downward, then if the thickness of the cutting workpiece is very large, the accuracy of the cutting will be reduced, then the slit cut out will be very large.

4. Cutting materials

 The cutting precision also depends on the cutting materials. For the same situation, the accuracy of cutting would be different cutting on stainless steel and Alloy. The the cutting precision would be more higher on stainless steel and the incision will be more smooth

Generally, the laser cutting quality should be judged by the following tips：

1. Cutting surface roughness

2. Incision hanging slag dimension

3. Slit edge perpendicularity and slope

4. Radius size of cutting slit edge

5. Flatness
