Fiber laser cutting machines are more efficient than traditional machining. Laser cutting technology greatly reduces processing time and production costs. More and more companies are choosing fiber laser cutting machines as processing and production tools. The cutting quality of fiber laser cutting machine is often the focus of the company. Let's look at the evaluation criteria of cutting quality and the method to achieve high quality cutting:

 

 First, the cut section is smooth, with few lines and no brittle fracture. When the fiber laser cutting machine cuts, the marks of the cutting will be displayed after the laser beam is deflected, so the speed is slightly lowered at the end of the cutting process, and the formation of the lines can be eliminated.

 

Second, the size of the slit width. This factor is related to the thickness of the cutting plate and the size of the nozzle. Under normal circumstances, the cutting thin plate has a narrow slit, and the selected nozzle is small because the amount of air jet required is relatively small. Similarly, the thick plate requires a large amount of air jet, so The nozzle is also large and the slit is widened accordingly. So to find the right type of nozzle, you can cut a good product.

 

Third, the cutting verticality is good, and the heat affected area is small. The perpendicularity of the cutting edge is important. When away from the focus, the laser beam will diverge. Depending on the position of the focus, the cutting becomes wider toward the top or bottom, and the more vertical the edge, the higher the cutting quality.
