Fiber laser cutting machine quality factors 2
Fiber laser cutting machine quality factors 2.
Last post,we talked about the fiber laser cutting machine,below are other factors.
6. Material deposition
The laser cutter hits a special oil-containing liquid on the surface of the work piece before it begins to melt the perforations.
During the cutting process, the customer blows off the cut with the wind
due to gasification and various materials are not used,
but the upward or downward discharge also forms a deposit on the surface.
7. Depression and corrosion
The depressions and corrosion have an adverse effect on the surface of the cutting edge,
affecting the appearance. They appear in cutting errors that should normally be avoided.
8. Heat affected zone
In laser cutting, the area near the slit is heated.
At the same time, the structure of the metal changes.
For example, some metals harden. The heat affected zone refers to the depth of the area where the internal structure changes.
If the cutting causes the part to heat up sharply, it will deform.
This is especially important in fine machining because the contours
and tabs here are usually only a few tenths of a millimeter wide.
Controlling laser power and using short laser pulses can reduce component heating and avoid distortion.
