Laser cutting machines that meet these several standards are good

2020-11-17

The purchase of a laser cutting machine is not the end for you to assemble it in place. The manufacturer also needs to debug the fiber laser cutting machine to ensure normal processing. This is also an inspection link, depending on the cutting quality, this is the most direct way to inspect the quality of the equipment. For new customers, when purchasing equipment, they will ask to see the metal laser cutting machine proofing first. In addition to the cutting speed of the equipment, the proofing depends on the cutting quality of the sample. Then how to look at the cutting quality and what aspects should be paid attention to? The editor will give you a detailed introduction below.

Laser cutting machines that meet several standards are good


1. Verticality

    If the thickness of the sheet metal exceeds 10mm, the verticality of the cutting edge is very important. When away from the focus, the laser beam becomes divergent, and the cut becomes wider toward the top or bottom depending on the position of the focus. The cutting edge deviates from the vertical line by a few hundredths of a millimeter. The more vertical the edge, the higher the cutting quality.

2. Roughness

    The laser cutting section will form vertical lines. The depth of the lines determines the roughness of the cut surface. The shallower the lines, the smoother the cut section. Roughness not only affects the appearance of the edge, but also affects the friction characteristics. In most cases, it is necessary to minimize the roughness, so the shallower the texture, the higher the cutting quality.

3. Texture

    When cutting thick plates at high speed, the molten metal will not appear in the cut below the vertical laser beam, but will spray out at the rear of the laser beam. As a result, curved lines are formed on the cutting edge, and the lines closely follow the moving laser beam. In order to correct this problem, reducing the feed rate at the end of the cutting process can greatly eliminate the formation of lines.

4. Cutting width

    Generally speaking, the cutting width does not affect the cutting quality. The cutting width has an important effect only when a particularly precise contour is formed inside the part. This is because the cutting width determines the minimum inner warp of the contour. When the thickness of the sheet increases, the cutting width also changes. The increase. Therefore, in order to ensure the same high accuracy, no matter how large the width of the cut, the workpiece in the processing area of the laser cutter should be constant.
