Reasons why laser engraving machine can not engrave metal materials

Laser cutting stainless steel, using the energy released when laserpecker pro 2 beam irradiates the surface of the steel plate, causing the stainless steel to melt and evaporate. For the manufacturing industry with stainless steel sheet as the main component, laser cutting stainless steel is a fast and effective processing method.

If you need to strictly manage and control the design parameters of laserpecker laser engraver cutting process in the process of processing and production, you can maintain the good corrosion resistance of such active materials. The most important process parameters affecting the quality of stainless steel cutting are cutting speed, laser power, air pressure and so on. Specific analysis of the problem and debugging ways and means are mainly as follows:

1. in the form of droplets to produce small, regular burrs

Possible causes

(1) focus is too low

(2) Feed rate is too high

Solution

(1) Raise the focal point

(2) Reduce the feed rate

2. Long irregular filiform burrs are produced on both sides, laserpecker 1 proand the surface of the plate is discolored.

Possible causes

(1) Feed rate is too low

(2) Focus is too high

(3) Air pressure is too low

(4) The material is too hot

Solution

(1) Increase the feed rate

(2) Lower the focus

(3) Increase air pressure

(4) Cool the material

Long, irregular burrs on one side of the cutting edge only

Possible causes

(1) Nozzle not centered

(2) Focus too high

(3) Air pressure too low

(4) Speed too low

Solution

(1) Center the nozzle

(2) Lower the focus

(3) Increase air pressure

(4) Increase speed

4、Material discharged from above

Possible causes

(1) Power is too low

(2) Feed rate is too large

(3) Air pressure is too high

Solution

In this case, immediately press the pause button to prevent the slag from splashing onto the focusing lens, increase the power, decrease the feed rate, and decrease the air pressure.

In addition to the common psychological problems through the above, it may also lead to the emergence of yellowing of cutting edges

Possible causes

Oxygen impurities in the nitrogen gas

Solution

Use high quality, high purity nitrogen gas
