If Poor Cutting Quality of Fiber Laser Cutting Machine,How to Deal with?

Fiber laser cutting machine is a kind of laser cutting method .It uses a fiber laser generator as the optical source. Fiber laser is a new type of laser beam . It outputs a high-energy-density laser beam which focuses on the surface of the workpiece, melting and vaporizing the area illuminated by the ultra-fine focal spot.  The numerical control mechanical system move the spot to achieve automatic cutting with high speed and high precision.

For beginners who are new to the fiber laser cutting machine, they will be in trouble when encountering poor cutting quality. How to adjust the machine in the face of numerous parameters? Let’s have a look at the solution!

The parameters that can affect the cutting quality mainly include: cutting height, cutting nozzle model, focus position, cutting power, cutting frequency, cutting duty cycle, cutting pressure and cutting speed. Hardware conditions include: protective lens, gas purity, sheet metals quality, focusing mirror and collimating mirror.

In the case of poor cutting quality,we recommend to conduct a general inspection on the fiber metal cutting machine first. The main inspection content and orders are:

 1.Firstly,Cutting height

Firstly,The actual cutting height we recommend is between 0.8-1.2mm. If it is not accurate, require the calibration work.

2.Secondly,Nozzle inspection

Secondly, Check whether the nozzle model and size are wrong. If it is correct, check if the cutting nozzle is damaged, or if the roundness is normal.

3.Thirdly,Optical center

Thirdly,We recommend to use a cutting torch with a diameter of 1.0mm for optical inspection. When checking the optical center, the focus is preferably between -1 and 1mm. The light spot thus produced is small and easy to observe.

4.Protective lens

Also, Check whether the protective lens is clean and free of water, oil and slag. Sometimes the lens is fog because of the weather or the cold auxiliary air.

5.focal lens–Focal point

Besides,Check whether we set the focal point correctly. If it is an auto-focusing cutting head, be sure to check if the focus is correct.

After check the above 5 items and there are no problems happening,we should modify the parameters according to the cutting effect.
