Common problems and solutions of laser cut stainless steel
The laser cutting machine always encounters some problems when laser cut stainless steel, resulting in poor cutting quality. The most important process that affects the quality of metal cutting is cutting speed, laser power, air pressure, etc., so it is necessary to solve common problems in stainless steel laser cutting Starting from the process point of view, if the process parameters of the laser cutting machine are strictly controlled during the processing process, the processing quality of the workpiece can be guaranteed.
The principle of laser cutting machine cutting metal materials is to use the energy released when the laser beam irradiates the surface of the steel plate to melt and evaporate the metal. For the manufacturing industry that uses stainless steel plates as the main component, laser cutting stainless steel is a fast and effective processing method. However, the laser cutting machine always encounters some problems in the process of cutting stainless steel, resulting in poor cutting quality. The most important process that affects the quality of metal cutting is cutting speed, laser power, air pressure, etc., so it solves common problems in stainless steel laser cutting To start from the perspective of technology, if the process parameters of the laser cutting machine are strictly controlled during the processing, the processing quality of the workpiece can be guaranteed.
1.produce small and regular burrs like drips
Pssible reasons: (1) Focus is too low (2) Feed rate is too high
Solution: (1) Raise the focus (2) Reduce the feed rate
2.Long irregular filamentous burrs are produced on both sides, and the surface of the large plate is discolored
Possible reasons: (1) Feed rate is too low (2) Focus is too high (3) Air pressure is too low (4) Material is too hot
Solution: (1) Increase the feed rate (2) Reduce the focus (3) Increase the air pressure (4) Cooling material
3. Only produce long irregular burrs on one side of the cutting edge
Possible reasons: (1) Nozzle is not centered (2) Focus is too high (3) Air pressure is too low (4) Speed is too low
Solution: (1) Center the nozzle (2) Lower the focus point (3) Increase the air pressure (4) Increase the speed
4. Material is discharged from above
Possible reasons: (1) Power is too low (2) Feed rate is too high (3) Air pressure is too high
Solution: When this happens, press the pause button immediately to prevent molten slag from splashing on the focusing lens, increase power, reduce feed rate, and reduce air pressure
5.Yellow cutting edge
Possible reason: nitrogen contains oxygen impurities
Solution: Use good quality and high purity nitrogen
