The quality of laser cutting machine mainly depends on its cutting quality, which is a better way to check the quality of equipment. For new users, when purchasing the equipment, they will ask to see how the laser cutting machine samples. In addition to the cutting speed of the equipment, the sample cutting quality should be looked at. How to look at the cutting quality of the laser cutting machine, and what aspects should be paid attention to?
The cutting quality of the laser cutting machine shall be checked from the aspects of burr, perpendicularity, cutting width, burning of cutting corners, heat affected areas, and deformation during processing.
The formation of burr is a very important factor to determine the quality of laser cutting. Because the removal of burr requires additional work, the severity and amount of burr can directly determine the quality of cutting.
Perpendicularity deviation
If the thickness of the sheet metal exceeds 10mm, the perpendicularity of the cutting edge is very important. When away from the focus, the laser beam becomes divergent, and the cutting becomes wider toward the top or bottom according to the location of the focus. The cutting edge will deviate from the vertical line by several millimeters. The more vertical the edge is, the higher the cutting quality will be.
Cutting width size
Generally speaking, the cutting width does not affect the cutting quality. Only when a particularly precise contour is formed inside the workpiece can the cutting width have an important impact. This is because the cutting width determines the minimum inner diameter of the contour. When the plate thickness increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how wide the incision is, the processing area of the object in the laser cutting machine should be constant.
Whether the cutting corner overburns seriously
The quality of the laser cutting machine can also be judged by whether the particularly fine corners are accurate and whether the overburn is serious during the cutting process.
Depth of heat affected zone
In laser cutting, the area near the incision is heated. At the same time, the structure of metal changes. For example, some metals harden. The heat affected area refers to the depth of the area where the internal structure changes.
Whether there is deformation during processing
If cutting causes the workpiece to heat up sharply, it will deform. This is particularly important in fine machining because the profile and connecting piece here are usually only a few tenths of a millimeter wide.
