Hi, nice to see you on Sundays. Today we will share a case of poor cutting, it is burnt edges. You could find the samples, parameters, and advice in this video. If you don’t know me yet, please subscribe to my channel and share to your friends, you could get much closer to basic information on industrial lasers. Let’s get started.
Let’s see two pictures first, it is 20mm carbon steel cut by a 6kw. Speed is 0.8 min/m, nozzle height 0.4mm, pressure 0.62 Mpa, 100% power and duty cycle, frequency 200, focus 18.2, nozzle single 1.6, could you figure out why the lower edge is burnt? Please tell me in below comments.
For debugging, there may never be a single factor that affects the entire cutting. Therefore, we need to inspect the reasons one by one. First, check whether the nozzle is hot, if it is, could it be because the focus is set a little too high? If the cutting textures on both sides are different, is it possible that the laser beam is not located in very center, or that the lens has black spots that are not in the center of the lens? If there is a kind of yellow edge on the bottom layer, the speed is usually too fast. How about to adjust the speed a little lower, such as 0.5?
Next, I would like to leave a question for you, 6kw, 20mm carbon steel, oxygen, please help me find the reason why the cut result is like this. Or you can share your parameters, I look forward to your comments.
