What are the methods of laser piercing by laser cutting machine?

When the laser cutting machine is cutting, as long as the correct operation is followed, there will  be any major problems,  the cutting effect is relatively good. If there are burrs  slag when using the equipment for processing  cutting, then it needs to be paid attention to. It is the key to find out the cause of the problem  solve it in time.

 How do glitches occur?

 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  vaporizes the surface of the workpiece to achieve the purpose of cutting. But there is a device here that we should pay attention to, that is, gas.

 The gas is to blow off the slag on the surface of the workpiece after the irradiation surface of the workpiece is vaporized. If the gas is  used, after the slag is cooled, burrs will form on the cutting surface. Therefore, the purity of the gas is higher. You can change to a gas supplier with a higher quality. The purity of the gas is very important. Do  use cylinder gas, because after two fillings, the purity is  good  the gas is wasted.

 Another reason is the quality of the equipment itself, as well as the parameter setting factors, so when the customer purchases the laser cutting machine , it is necessary for an experienced operator to debug the equipment. Therefore, it is necessary to adjust the cutting parameters to be as good as possible. The air pressure, flow focal length  cutting speed, etc., have to be adjusted many times. The parameters provided by the machine cannot cut high-quality workpieces.

 If a material has burrs, the material can be qualitatively defective. The more burrs, the lower the quality.

Generally speaking, when the burr appears in the laser cutting machine, it can be investigated  solved  the following aspects:

  1. The output power of the laser cutting machine is  enough.

 Solution: Check whether the laser cutting machine works normally. If it is abnormal, it needs timely repair  maintenance. If it is normal, check whether the output value is correct.

  2. The upper  lower positions of the focal point of the beam are deviated.

  Solution: Adjust the position of the focus,  adjust it according to the offset position.

  3. The gas purity of the cutting machine is  enough.

  Solution: Change gas.

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

  Solution: Adjust the wire cutting speed in time.

  5. The dot of the laser beam of the cutting machine has shifted.

 Solution: Perform focus adjustment  timely adjustment

Fiber laser cutting machine is a precise machine, often a data error will cause its work to run abnormally, so it should be strict in the work  reduce the occurrence of errors. Some small problems are factors that may cause burrs  slag to appear on the laser cutting machine, so I hope everyone can solve them when facing such problems.
