The best way to judge the performance of laser cutting equipment is to judge the processing quality and cutting effect of optical fiber cutting machine. The manufacturer of optical fiber cutting machine sorts out the following points to help customers judge equipment performance:

1. Whether the cutting surface is rough

The smoother the cutting surface, the higher the performance of the optical fiber cutter. The processing part of the laser cutting machine will form a vertical line, and the depth of the line determines the roughness of the cutting surface. Roughness not only affects the appearance of edges, but also affects the friction characteristics of edges. In most cases, roughness must be minimized.

2. Whether the longitudinal angle is vertical

After the optical fiber cutting machine is processed, the more vertical the workpiece edge is, the better the cutting quality of the equipment is. If the thickness of the metal plate exceeds 10mm, the laser beam will be scattered. The cutting edge will gradually deviate from the vertical line when cutting to the top or bottom according to the focus position. The angle produced is very important. If the angle deviation causes excessive cutting gap, which seriously affects the processing accuracy.

3. Cutting gap

Generally, the cutting gap of optical fiber cutting machine does not affect the cutting quality, and the cutting gap is only important when a part of the workpiece needs to form a particularly accurate contour. This is because the cutting gap determines the minimum internal longitude of the contour, and the cutting gap increases with the increase of the plate thickness. Therefore, in order to ensure the same high accuracy, regardless of the cutting width, the workpiece in the processing area of the optical fiber cutting machine should be constant.

4. Texture

When cutting plates at high speed, the molten metal will not appear in the notch below the vertical laser beam, but will be ejected behind the laser beam. The results show that the curve formed at the cutting edge is closely related to the curve moving along the laser beam. In order to correct this problem, reducing the feed rate at the end of the cutting process can eliminate the line formation.

5. Burrs

The formation of burr determines a very important factor of laser cutting quality. Because burr removal requires extra work, the severity and number of burr can be judged intuitively to determine the performance of the fiber cutting machine.

6. Material deposition

Before the optical fiber cutting machine starts to melt the workpiece and perforate, if it encounters some special liquid such as antirust oil on the workpiece surface. During the cutting process, due to gasification and improper use of various materials, the equipment will be blown open with air, but the iron slag melted up and down will also deposit on the surface of the workpiece, resulting in the workpiece can not be used.

7. Depression and corrosion

The concave and corrosion have adverse effects on the edge cutting surface of the optical fiber cutting machine, which will affect the appearance of the workpiece. This is a problem that should not occur with a normal quality optical fiber cutter.

8. Heat affected degree

The smaller the heating area, the higher the equipment quality. During the processing of the optical fiber cutting machine, the area near the notch is heated. At the same time, the structure of metal has also changed. For example, some metals may become soft, and the heating zone refers to the depth of the area where the internal structure changes.

9. Deformation

If the optical fiber cutting machine causes a sharp increase in the heat of the part, it will deform. This is particularly serious in fine processing, because the contour of these workpieces and connectors are usually only a few tenths of a millimeter wide. Control the power of the optical fiber cutting machine, and use short laser pulses to reduce the heat of parts and avoid deformation.
