Fiber laser cutting machines are very common in the application of sheet metal processing across industries. However, in the process of sheet metal processing, the screams and burrs at the transition of the workpiece surface directly affect the quality of the processed workpiece. Although some products have taken the deburring process in the production process, the problem of looking at the burrs has not been completely solved. So many users began to suspect the product quality of the laser cutting machine. In fact, this is not the case.
First of all, we must first understand how glitches are produced?
In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the surface of the workpiece vaporizes and evaporates the surface of the workpiece to achieve the purpose of cutting. But here is a device that we must pay attention to, which is gas.
The gas is to blow off the slag on the surface of the workpiece when the irradiated surface of the workpiece is vaporized. If no gas is used, after the slag cools, it will form burrs attached to the cutting surface. Therefore, the purity of the gas must be high, and the purity of the gas is very important. Do not use cylinder gas, because after two fillings, the purity is not good and the gas is wasted. In the process of sheet metal processing, if the equipment + gas + parameters are adjusted to the best, the cut workpiece will be free of burrs.
Another reason is the quality of the equipment itself, as well as the parameter setting factor. Therefore, when the customer purchases the laser cutting machine, it is necessary to let an experienced operator debug the equipment. Therefore, the cutting parameters should be adjusted as best as possible. The air pressure, flow, focal length, and cutting speed must be adjusted many times. High-quality workpieces cannot be cut only by the parameters provided by the machine. Therefore, it is recommended to consider after-sales service as an important inspection item when purchasing laser cutting machine equipment.
In addition, during the sheet metal processing of the laser cutting machine, improper silver operation, technical problems, and the quality of the processed materials may cause burrs on the processed workpiece. If a piece of material has burrs, then the material can be qualitatively defective. The more burrs, the lower the quality. This will leave problems for the subsequent inspection, assembly, performance and appearance of the product.
So, how to solve the problem of high burrs during the sheet metal processing of the laser cutting machine?
Generally speaking, when the laser cutting machine has burrs, it can be checked and solved from the following aspects:
1. The output power of the laser cutting machine is not enough.
Solution: Check whether the laser cutting machine is working properly. If it is abnormal, it needs timely repair and maintenance. If it is normal, check whether the output value is correct.
2. The upper and lower positions of the focal point of the beam are deviated.
Solution: Adjust the position of the focus and adjust it according to the offset position it produces.
3. The gas purity of the cutting machine is not enough.
Solution: Change the gas.
4. The wire cutting speed of the cutting machine is too slow.
Solution: Adjust the wire cutting speed in time.
5. The application point of the laser beam of the cutting machine is shifted.
Solution: Debug the focus and make adjustments in time
6. The instability of the laser cutting machine running for too long.
Solution: Turn off the machine and restart it and let the machine rest.
The laser cutting machine is a precision machine, and often a data error will cause its work to run abnormally, so it must be strict in the work to reduce errors.
The above is a sharing of the reasons and solutions for the easy burrs of laser cutting machines in sheet metal processing. If you need to understand or solve more problems, you can leave a message, datolaser will reply to you as soon as possible.
