The accuracy of the laser cutting machine often affects the quality of cutting, and the products cut by the laser cutting machine’s accuracy deviation are unqualified, wasting manpower and material resources. How to improve the accuracy of laser cutting machine?
The first is focus position control technology. The smaller the focal depth of the focusing lens, the smaller the focal spot diameter. Therefore, it is very important to control the position of the focus relative to the surface of the material being cut.
The second is cutting perforation technology. Any thermal cutting technique, except in a few cases, which may start from the edge of the board, usually requires a small hole through the board. In the early laser stamping compound machines, punches were used to punch holes, and then lasers were used to cut from the holes.
The third is the mouth design and airflow control technology. When laser cutting steel, oxygen and a focused laser beam are directed to the material to be cut through a nozzle to form an air stream. The basic requirement for air flow is that the flow rate into the incision should be large and the speed should be high, so that enough oxidation can make the incision material fully exothermic reaction. At the same time, there is enough momentum to eject the molten material.
Laser cutting has no burrs, wrinkles and high precision, which is better than plasma cutting. For many electromechanical manufacturing industries, because the computer programs of modern laser cutting systems can easily cut workpieces of different shapes and sizes (workpiece drawings can also be modified), it is often more favored than punching and forming processes; although its processing The speed is slower than die punching, but it has no die consumption, no need to repair the die, and saves the time to replace the die, thereby saving the processing cost and reducing the product cost, so it is more economical in general. This is why it is popular. Adjust the laser cutting machine equipment according to the above method, I believe it can help your laser cutting machine equipment to further improve the cutting accuracy!
