How to identify cutting quality problems for metal fiber laser cutting machine

Reading Time: 3 minutes

As an efficient sheet metal processing tool, metal fiber laser cutting machines have been widely used in various industries. Many people do not know how to judge the processing quality of the metal fiber laser cutting machine when they buy the metal fiber laser cutting machine. They are often blind and sometimes ignore the more important quality standards.

Usually we judge the cutting quality and the reliability of the whole product through the following points:

1. Roughness

Metal fiber laser cutting machine is a high-quality and efficient processing tool. When the fiber laser beam acts on the metal sheet, vertical lines will be formed. The deeper the lines, the rougher the surface of the section. When the power of the cutting machine matches the thickness of the sheet, the section cut by the metal fiber laser cutting machine is smooth, without streaks, and without brittle fracture. Roughness not only affects the appearance of the edges, but also the friction characteristics. In most cases, the lower the roughness, the higher the cut quality.

2. Verticality

For high-power metal fiber laser cutting, when the thickness of the processed material exceeds 10mm, the verticality of the cutting edge is very important. When away from the focus, the fiber 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. To

3. Cutting width

Generally speaking, the cutting width does not affect the cutting quality, but when a particularly precise contour is formed inside the component, the cutting width determines the minimum inner diameter of the contour. 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 in the processing area of ​​the fiber laser cutting machine should be constant.

4. Burr

During the processing of the metal fiber laser cutting machine, the high energy generated by the fiber laser beam irradiating the surface of the workpiece quickly vaporizes and evaporates the surface of the workpiece, and the slag on the surface of the workpiece is blown off by the auxiliary gas. If the auxiliary gas is not used, after the slag cools, burrs will be formed and attached to the cutting surface. Because the removal of burrs requires extra work, the quality of cutting can be intuitively judged by observing the number of burrs. To

Common processing materials for fiber optic laser cutting machines include stainless steel, carbon steel, aluminum, copper and other materials. Fiber optic laser cutting technology is developed along with the development of the sheet metal processing industry and plays an important role in promoting social production progress.
