  How to deal with the slag hanging in the process of laser cutting?

  When the laser cutting machine is cutting, as long as the correct operation is followed, there will not be any big problems, and the cutting effect is better. If there is burr and slag hanging when using the equipment for processing and cutting, it is necessary to pay attention to it. The key is to find out the cause of the problem and solve it in time.

  How is burr produced?

  In fact, burr is the surface of metal materials too many residual particles. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the workpiece surface makes the workpiece surface vaporize and evaporate to achieve the purpose of cutting. But here's a device that we need to pay attention to, which is gas.

  Gas is to blow off the slag on the surface of the workpiece after the gasification of the irradiation surface of the workpiece. If gas is not used, the slag will form a burr attached to the cutting surface after cooling. Therefore, the purity of gas should be high. You can change to a gas supplier with higher quality. The purity of gas is very important. Do not use cylinder gas, because after two filling, the purity is not good, and gas is wasted.

  Another reason is the quality problem of the equipment itself, and the parameter setting factor, so when the customer purchases the laser cutting machine, he should let the experienced operator debug the equipment. Therefore, it is necessary to adjust the cutting parameters as well as the cutting speed of air pressure flow focal length. It is necessary to adjust the cutting speed for many times. The parameters provided by the machine can not cut high-quality workpieces.

  If there is burr in a material, the material can be qualitatively defective. The more burr, the lower the quality.

  Generally speaking, when there is burr in laser cutting machine, it can be checked and solved from the following aspects:

  1. The output power of laser cutting machine is not enough.

  Solution: check whether the laser cutting machine works normally. If it is abnormal, it needs to be repaired and maintained in time. If it is normal, check whether the output value is correct.

  2. The upper and lower positions of the focus of the beam deviate.

  Solution: adjust the focus position according to the offset position.

  3. The gas purity of the cutter is not enough.

  Solution: change gas.

  4. The wire cutting speed of the cutter is too slow.

  Solution: adjust the wire cutting speed in time.

  5. The laser beam of the cutter is offset.

  Solution: debug the focus and adjust it in time

  Fiber laser cutting machine is a precise machine, often a data error will cause its abnormal operation, so it should be strict in the work, and reduce errors.

  Some small problems are factors that may lead to burr and slag on the laser cutting machine, so we hope that we can solve them when facing this problem.
