These Factors Affect The Quality Of Laser Cutting Machine

With the continuous development of science and technology, lasers are used for more and more field.  Laser cutting machine becomes a very common cutting equipment and used for many kind of industry.

For new customers, when purchasing equipment, they will ask to see the laser cutting machine proofing first. In addition to the cutting speed of the equipment, the cutting quality is a more important factor to check effect of the machine. Which indicators reflect the cutting quality of the laser cutting machine?  Let's give you a detailed introduction.

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.

Verticality

When we cut the sheet, it is usually achieved by computer graphics and laser cutting machine. If the thickness of the sheet metal exceeds 10mm, the verticality of the cutting edge becomes particularly 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 deviates from the vertical line by a few hundredths of a millimeter. The more vertical the edge, the higher the cutting quality.

Cutting width

In general, the cut width does not affect the cutting quality, and only when a particularly precise contour is formed inside the part, the cut width has an important effect. This is because the cutting width determines the minimum inner warp of the profile. When the thickness of the sheet increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how large the width of the cut, the workpiece should be relatively stable in the processing area of the laser cutting machine.

Texture

When cutting thick plates with 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 reduce the generation of lines.

Smoothness

Smoothness is a very important factor in judging the quality of laser cutting. Because it takes extra work to make the cutting surface smoother, the smoothness can directly reflect the cutting quality of the laser cutting machine.

The above are the major factors that affect the cutting quality of laser cutting machines. In addition to these factors, many comprehensive factors need to be considered. When we choose a laser cutting machine, we can choose the type of laser cutting machine according to the sheet cut on weekdays!
