CNC sheet metal fiber laser cutting machine using details – Jennifer

Today, we are going to share the tips, including the CNC sheet metal fiber laser cutting machine

1. Roughness in CNC sheet metal fiber laser cutting machine

Laser cutting cross-section will form vertical lines. The depth of the grain determines the cutting surface roughness. The lighter the grain, the more smooth cutting section. Roughness not only affects the appearance of the edge, but also affects the friction characteristics, in most cases, the need to reduce the roughness, so the lighter the grain, the higher the cutting quality.

2. Vertical degree in CNC sheet metal fiber laser cutting machine

How the thickness of the sheet metal exceeds 10mm, the vertical degree of cutting edge is very important. As far away from the focus, the laser beam becomes divergent, and the cutting is widened toward the top or bottom according to the position of the focus. The cutting edge deviates from the vertical line a few millimeters. The edge is perpendicular, the cutting quality is higher.

3. Cutting width in CNC sheet metal fiber laser cutting machine

Incision width generally does not affect the cutting quality, only in the part of the formation of a particularly precise contour, cutting width is important, this is because the cutting width determines the profile of the smallest internal, when the thickness of the sheet increases, cutting width also increases. So to ensure the same high accuracy, regardless of the width of the incision, the workpiece in the laser cutting machine for metal plates processing area should be constant.

4. Grain in CNC sheet metal fiber laser cutting machine

When cutting thick plates at high speed, the molten metal does not appear in the incision below the vertical laser beam, but it is sprayed out at the back of the laser beam. As a result, the curved lines formed at the edge of the cutting, the veins tightly followed the moving laser beam, in order to correct the problem, the cutting process at the end of the lower feed rate, you can greatly eliminate the line.

5. Burr in CNC sheet metal fiber laser cutting machine

The formation of burrs determines the quality of laser cutting a very important factor, because the burr removal requires extra work, so the severity of the burr and how much can be intuitive to judge the quality of cutting.

6. Material deposition in CNC sheet metal fiber laser cutting machine

The laser cutter encounters a special oil-containing liquid on the workpiece surface before starting the melting hole. Gasification and various, the material does not use the customer to blow the cut with the wind, but the upward or downward discharge will also form deposition on the surface.

7. Depression and corrosion in CNC sheet metal fiber laser cutting machine

Pitting and corrosion have an adverse effect on the surface of the cutting edge and affect the appearance. They appear in the usual cutting error that should have been avoided.

8. Heat-Affected areas in CNC sheet metal fiber laser cutting machine

In laser cutting, the area near the incision is heated. At the same time, the structure of the material changed. For example, some materials can harden. The heat-affected zone refers to the depth of the area in which the internal structure changes, and the lower the depth, the better in fiber metal laser cutting machine.

9. Deformation in CNC sheet metal fiber laser cutting machine

If the cutting makes the parts heated up sharply, it will deform. This is particularly important in fine-grained processing, where the outlines and connectors are usually only a few millimeters wide. The control of laser power and the use of short laser pulses can reduce the heat of parts and avoid deformation.
