The laser cutting process is closely related to many factors, such as the power of the laser in the process of cutting the product, the focus position, the purity of the auxiliary gas when cutting the material, the size of the air pressure, the speed of the cutting material, the material of the plate being cut, and the material being cut. Whether the surface quality of the plate is rusty or has debris, etc., the difference of these factors will directly affect the laser cutting process.

Common problem：

Question1:The cutting surface texture is very rough

possible reason:The focus is too high; the air pressure is too high;The feed rate is too low; the material is too hot.

Solution:Reduce focus; reduce air pressure;Increase the feed rate; cool the material.

Question2:The traction line is inclined and the bottom becomes narrower

possible reason:The feed rate is too high.

Solution:Reduce the feed rate.

Question3:The cutting surface is not precise

possible reason:The air pressure is too high; the nozzle is damaged;The nozzle diameter is too large; the material is not good.

Solution:Reduce the air pressure; replace the nozzle;Install suitable nozzles;Use materials with a smooth and uniform surface.

Question4:The workpiece is not cut through

possible reason:Processing gas error (N2);The feed rate is too high;Power is too low; focus is too low.

Solution:When this happens, press the pause button immediately,To prevent molten slag from splashing on the focusing lens;Use oxygen as processing gas;Reduce the feed rate;Increase power; raise focus.

Question5:There are burrs only on one side of the cut of the sheet

possible reason:Incorrect nozzle alignment; defective nozzle opening.

Solution:Center the nozzle; change the nozzle.

Question6:The bottom incision is wider, and the traction line deviates greatly

possible reason:The feed rate is too high; the laser power is too low;The air pressure is too low; the focus is too high.

Solution:Reduce the feed rate; increase the laser power;Increase air pressure; decrease focus.

Question7:The burrs on the bottom surface are dripping and easy to remove

possible reason:The feed rate is too high;The air pressure is too low; the focus is too high.

Solution:Reduce the feed rate;Increase air pressure; decrease focus.
