How to solve the problem of burnt and yellow edges in laser cutting acrylic

To avoid producing burnt or yellow edges when cutting acrylic sheets, the following methods can be adopted:

1. Using high-power laser cutting machines: High power laser cutting machines can quickly and accurately complete cutting tasks, reducing the possibility of producing focal edges during cutting.

2. Adjusting the parameters of the laser cutting machine: By adjusting the parameters of the laser cutting machine, such as laser power, cutting speed, and focal position, the cutting effect can be optimized and the generation of focal edges can be reduced.

3. Using auxiliary gas: During the cutting process, using auxiliary gas (such as nitrogen) can help blow away the heat and smoke generated during cutting, thereby reducing the formation of focal edges.

4. Choosing high-quality acrylic sheets: Choosing acrylic sheets with good quality and uniform thickness for cutting can reduce uneven heating during cutting and lower the probability of edge burning.

5. Using a vibrating knife cutting machine: The vibrating knife cutting machine uses blade cutting instead of laser thermal melting cutting, which can effectively avoid the generation of focal edges and yellow edges. According to the thickness of acrylic, milling cutters, vibrating cutters, and starting cutters can be selected, among which milling cutters have the best cutting effect, exquisite cutting arc edges, and faster cutting efficiency than laser cutting machines.

In summary, by selecting appropriate cutting equipment, adjusting cutting parameters, using auxiliary gases, and selecting high-quality acrylic sheets, the problem of burnt edges and yellow edges during acrylic sheet cutting can be effectively avoided.
