The cutting precision of the laser cutting machine often affects the quality of the cutting, and the products cut out after the precision of the laser cutting machine deviates are unqualified. So, in the process of using the laser cutting machine, how should we improve the cutting accuracy of the laser cutting machine? Today Leapion laser to share.
The smaller the spot after the laser beam is concentrated, the higher the precision of laser cutting, especially the smaller slit, the smallest spot can reach 0.01mm.
The positioning accuracy of the worktable determines the repeatability of the laser cutting process. The higher the accuracy of the worktable, the higher the cutting accuracy.
The larger the workpiece thickness, the lower the accuracy and the larger the kerf. Since the laser beam is tapered, the slit is also tapered, and the material with a thickness of 0.3MM is much smaller than the slit of 2MM.
The workpiece material has a certain influence on the laser cutting accuracy. In the same case, the cutting accuracy of different materials is slightly different, even if the same material, if the composition of the material is different, the cutting accuracy will also be different.
The smaller the focal depth of the focusing lens, the smaller the light spot at the focal point. Therefore, the focal position is controlled on the metal surface to effectively improve the cutting quality.
Any thermal cutting technique, except in a few cases where it can start from the edge of the board, generally has to make a small hole in the board. Since the laser cutting machine belongs to thermal cutting, it is also necessary to penetrate a small hole in the metal plate first, and then the laser beam starts to cut the plate from the small hole.
In the process of sheet metal processing by the laser cutting machine, oxygen is squeezed through the nozzle and the laser beam acts on the surface of the material to be cut. The basic requirements for the airflow are large flow and high speed, so as to ensure that there is enough oxygen to interact with the material. Thermal reaction, and at the same time there is enough air flow to blow the slag away.
The processing speed of the laser cutting machine has a great influence on the cutting accuracy. When the processing speed of the laser cutting machine is too fast, the workpiece cannot be cut through, resulting in the workpiece being scrapped. Or the cutting speed is too slow, causing burn marks on the cutting edge, affecting the accuracy. Therefore, before cutting, it is necessary to try to adjust the appropriate processing speed.
When making product processing drawings, it is necessary to accurately set the operator's settings and the plan of the design drawing to minimize unnecessary errors.
Before processing the workpiece, it is necessary to approve the stability of the laser cutting machine's processing table, so as not to reduce the machining accuracy due to the shaking of the table during processing.
