If the CNC fiber laser cutting machine process parameters are strictly controlled during the processing, the good corrosion resistance of this type of material can be maintained. The important process parameters that affect the quality of stainless steel cutting are cutting speed, laser power, air pressure, etc.

1. Produce drop-like small regular burrs.

Possible Causes:

(1)The focus is too low

(2) Feed rate is too high

Solution:

(1) Raise focus

(2) Reduce the feed rate

2. Long irregular filament-like burrs are produced on both sides, and the surface of the large plate becomes discolored.

Possible Causes:

(1)Fiber laser cutting machine Feed rate is too low

(2)The focus is too high

(3)Air pressure is too low

(4) The material is too hot

Solution:

(1) Increase the feed rate

(2) Reduce focus

(3) Increase atmospheric pressure

(4) Cooling material

3. Long irregular burrs are only produced on one side of the cutting edge.

Possible Causes:

(1) Fiber laser cutting machine the nozzle is not centered

(2)The focus is too high

(3)Air pressure is too low

(4)Speed is too low

Solution:

(1) Centering nozzle

(2) Reduce focus

(3) Increase atmospheric pressure

(4) Increase speed

4. Materials are discharged from above

Possible Causes:

(1)Power is too low

(2) Feed rate is too large

(3) The air pressure is too high

Solution:

(1) When this happens, press the pause button immediately to prevent slag from splashing on the focusing lens.

(2) Increase power

(3) Reduce the feed rate

(4) Reduce air pressure

5. In addition to the above common problems,fiber laser cutting machine there may also be the problem of yellowing of the cutting edges.

Possible Causes:

Nitrogen contains oxygen impurities

Solution:

Use good quality, high purity nitrogen
