Good cutting quality of fiber laser cutter 2
Good cutting quality of fiber laser cutter 2.
In last post,i have shown some factors to you,there are still some factors as below.
How the thickness of the sheet metal exceeds 10 mm, the perpendicularity of the cutting edge is very important. When away from the focus, the laser beam becomes divergent, and depending on the position of the focus, the cut becomes wider toward the top or bottom. The cutting edge is a few hundredths of a millimeter from the vertical line, and the more vertical the edge, the higher the cutting quality.
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.
8. Cutting width.
The width of the slit generally does not affect the quality of the cut. The cut width has an important effect only when a particularly precise contour is formed inside the part. This is because the width of the cut determines the minimum meridian of the profile. As the thickness of the sheet increases, the width of the cut also Increase. Therefore, to ensure the same high precision, regardless of the width of the slit, the workpiece should be constant in the processing area of the laser cutting machine.
When the slab is cut at high speed, the molten metal does not appear in the slit below the vertical laser beam, but instead is ejected after the laser beam is deflected. As a result, the curved lines are formed at the cutting edge, and the lines closely follow the moving laser beam. To correct this problem, the feed rate is lowered at the end of the cutting process, and the texture of the lines can be greatly eliminated.
