Four factors of fiber laser cutting effect

Four factors of fiber laser cutting effect.

For new customers, when purchasing equipment, they will be required to look at the laser cutting machine for proofing. In addition to proofing the cutting speed of the equipment, that is to see the cutting quality of the sample, so how to look at the cutting quality, what aspects should focus on?

1.Verticality.

If the thickness of the sheet metal exceeds 10mm, the verticality of the cutting edge is very important. When away from the focal point, the laser beam becomes divergent, and depending on the position of the focal point, the cut becomes wider toward the top or bottom. The cutting edge is a few millimeters away from the vertical line. The more vertical the edge, the higher the cutting quality.

2. Roughness.

The laser cutting section will form vertical lines. The depth of the lines determines the roughness of the cutting surface. The lighter the lines, the smoother the cutting surface. Roughness affects not only the appearance of the edges, but also the friction characteristics. In most cases, it is necessary to reduce the roughness as much as possible, so the shallower the texture, the higher the cutting quality.

3.Texture.

When cutting thick plates at high speeds, molten metal does not appear in the cuts under the vertical laser beam, but instead sprays out at the rear of the laser beam. As a result, curved lines are formed at the cutting edge, and the lines closely follow the moving laser beam. To correct this problem, reducing the feed rate at the end of the cutting process can greatly eliminate the formation of lines.

4. Cutting width.

Generally speaking, the cut width does not affect the cutting quality. Only when a particularly precise contour is formed inside the part, the cutting width has an important effect. This is because the cutting width determines the minimum inner diameter of the contour. Increase. Therefore, we want to ensure the same high accuracy, regardless of the width of the cut, the workpiece should be constant in the processing area of ​​the laser cutting machine.
