1. Add a cooling point or use the ring cutting function

　　When the 50w co2 laser engraving and cutting machine cuts a sheet with sharp corners, the position where overburning is more likely to occur is often at the sharp corners. Overburning will cut the sharp corners into a round shape. Point, pause at the sharp corner, and blow air, which can effectively avoid over-burning.

　　2. Use high-power lasers

　　50w co2 laser engraving and cutting machine can use higher power lasers when cutting carbon steel. The bright surface cutting process can effectively avoid over-burning, and this cutting process can cut burr-free and brightly cut finished products.

　　3. Nitrogen cutting

　　In sheet metal cutting with oxygen as auxiliary gas, nitrogen can be switched for cutting.

　　4. Increase the air pressure

　　When using 50w co2 laser engraving and cutting machine to process aluminum alloy and stainless steel, the auxiliary gas used is nitrogen or air, and no edge burning occurs during cutting, but due to the high temperature of the material inside the small hole, the phenomenon of slag hanging on the inside will be more frequent. In this case, burrs and slag can be reduced by increasing the pressure of the auxiliary gas.
