Nine standard determine to fiber laser cutting machine cutting quality
To determine the quality of fiber laser cutting machine quality is the most intuitive to determine the best performance of laser cutting equipment, here we list some of the nine standard.
fiber laser cutting machine section will form a vertical pattern, the depth of the groove determines the roughness of the cutting surface, the more shallow the lines, the more smooth cutting section.
Roughness not only affects the appearance of the edge, but also affect the friction characteristics,
in most cases, the need to minimize roughness, so the more shallow lines, the higher the quality of cutting.
If the thickness of the sheet metal exceeds 10mm, the verticality of the cutting edge is very important. Far away from the focus, the laser beam becomes divergent, depending on the position of the focus, the cutting is widened toward the top or bottom.
The cutting edge deviates from the vertical line by a few millimeters, the more vertical the edge, the higher the cutting quality.
3. Cutting width.
The width of the cut does not generally affect the quality of the cut, and the cut width has an important effect only when a particularly precise profile is formed inside the part.
This is because the cutting width determines the minimum internal meridian of the contour. When the plate thickness increases, the cutting width The increase.
So want to ensure the same high precision, no matter how much the width of the workpiece, the workpiece in the fiber laser cutting machine processing area should be constant.
When cutting a thick plate at high speed, the molten metal does not appear in the incision beneath the vertical laser beam, but is ejected later than the laser beam.
As a result, the curved lines are formed at the cutting edge, and the lines follow the moving laser beam.
To correct this problem, the feed rate is reduced at the end of the cutting process, and the behavior of the lines can be largely eliminated.
The formation of the burrs determines a very important factor in the quality of the laser cutting, since the removal of the burrs requires additional effort,
so the amount of burr is serious and how much is able to visually determine the quality of the cut.
6. Material deposition. fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine
The fiber laser cutting machine touches a layer of oil containing special liquid on the surface of the workpiece before it begins to melt and pierce.
During the cutting process, due to gasification and various materials do not use, customers with wind blowing in addition to the incision,
but the upward or downward discharge will also form deposition on the surface.
7. Depression and corrosion.
Depression and corrosion have an adverse effect on the surface of the cutting edge, affecting the appearance. They appear in the general should be avoided in the cutting error.
8. Heat affected area.
In metal fiber laser cutting machine , the area is heated along the area near the incision. At the same time, the structure of the metal changes.
For example, some metal will harden. The heat affected area refers to the depth of the area where the internal structure changes
9. Deformation. fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine
If the cutting makes the part heated abruptly, it is deformed.
This is especially important in fine machining because the contours and connectors here are usually only a few tenths of a millimeter wide.
Controlling laser power and using short laser pulses can reduce component heat and avoid deformation.
