Fiber laser cutting machine has the advantages of high cutting precision, fast speed, cost saving, etc., which has created the wide application of fiber laser cutting machine in the market, and also let more people know about its purchase. Anyone who has used a laser cutting machine knows that the laser cutting effect is controlled by cutting parameters such as auxiliary air pressure, laser power, cutting speed, and focus position. As for how to adjust the equipment parameters during use, most people will refer to the laser The instruction manual of the cutting machine, the cutting material, material thickness and cutting speed in the instruction manual will be marked in detail. For beginners, it will be difficult when the cutting quality is not good, and they do not know how to adjust in the face of many parameters. The following is a brief introduction to the problems and solutions that will be encountered by the editor of Baiwei Laser.

The parameters that affect the cutting quality are: cutting power, cutting height, focus position, cutting nozzle model, cutting frequency, cutting duty cycle, cutting air pressure and cutting speed. The hardware conditions are: gas purity, protective lens, sheet quality, focusing lens and collimating lens.

How to adjust the parameters of the laser cutting machine?
In case of quality problems in cutting, it is recommended to check first. The main inspection contents and order are:
1. Cutting height (recommended actual cutting height is between 0.8~1.2mm), if the actual cutting height is not accurate, it needs to be calibrated.
2. Focus Check whether the focus is set correctly. If it is an auto-focusing cutting head, you must use the mobile APP to check whether the focus is correct.
3. It is recommended to use a cutting nozzle with a diameter of 1.0 to check the optical center. When checking the optical center, the focus is between -1 and 1. The light spot produced in this way is small and easy to observe.
4. Cutting nozzle Check whether the model and size of the cutting nozzle are used incorrectly. If it is correct, check whether the cutting nozzle is damaged.
5. Protective lens Check whether the protective lens is clean, requiring no water, no oil and no residue. Sometimes the protective lens fogs up due to the weather or the cold air.
6. Modify cutting parameters
After several checks and there are no problems, modify the parameters according to the phenomenon.

How to adjust the parameters according to the phenomenon?
The following is a brief introduction to the conditions and solutions encountered when cutting stainless steel and carbon steel. For example, stainless steel slag, there are many types of slag. If there is hard slag on the whole, it is necessary to reduce the focus, increase the air pressure, and increase the cutting nozzle. However, if the focus is too low or the air pressure is too high, the section will be delaminated and the surface will be rough. If the whole body hangs with granular soft slag, the cutting speed can be appropriately increased or the cutting power can be reduced. If only the slag hangs on the corner, the corner rounding can be considered first. In terms of parameters, the focus can be reduced and the air pressure can be increased.
