In the whole process of sheet metal processing, there are many cases in which people do not know how to judge the quality of sheet metal processing, today's high precision sheet metal processing of me to explain to you in the application of laser cutting machine processing metal materials, sheet metal processing in how to judge the quality of the sheet metal parts laser.
1. Smooth cutting surface, less wire frame, no brittle break
When laser cutting is carried out under continuous high temperature, the imprint of the melted raw material does not easily occur in the trauma under the vertical laser beam, but instead it will be sprayed out behind the laser beam. A curve pattern is produced at the cutting edge and this curve has to follow the moving laser beam firmly. To solve this problem completely, it is necessary to reduce the walking rate at the completion of the full cutting process can significantly remove the generation of the wireframe.
2. Narrow double slit widths
The width of the cut does not usually compromise the quality of the cut. The cutting width only plays a major role when the internal structure of the part produces a particularly precise corridor. This is due to the fact that the cutting width determines the minimum internal structural rise and shrinkage of the aluminium profile. As the thickness of the sheet increases, the cutting width also increases. This is because the width of the cut increases as the thickness of the plate increases. Thus, if the same high precision is to be guaranteed, no matter how wide the cutting width is, the processing area of the laser cutting machine should make the product workpiece maintain stability.
3. Good vertical angle of the gap, the total area of thermal damage is small
When processing the thinness of the raw material beyond 18mm, the flatness of the cutting edge is very critical. When away from the focus, the laser beam emanates and the cut will widen towards the top or bottom depending on the part of the focus. The cutting edges are spaced a few millimetres apart in a vertical orientation. The straighter the edge, the higher the quality of the cut.
