CO2 laser machines are ideal for engraving and cutting acrylic materials. Because the acrylic processed by CO2 laser cutting machine has an amazing effect. Other techniques, such as CNC routers or dicing saws, often leave blurry edge colors. The processed product requires secondary processing to achieve polishing. However, the acrylic sections cut by the laser beam are smooth and polished, eliminating the need for subsequent processing.

When laser cutting acrylic sheets, a thin sheet of acrylic usually cuts easily. But sometimes when cutting thick acrylic materials, you may experience uneven cutting edges. What’s worse, when processing colored acrylic, the cut kerf will turn white. Having a few laser cutting skills can improve the results of cutting thick acrylic. The following points serve as a reference when cutting acrylic.

CHECK THE POWER OF LASER CUTTING MACHINE

For CO2 laser cutting thick acrylic, you need high enough wattage to get the job done. For thinner sheets such as 3mm acrylic, cutting on 150W or 200W can be successful. But if you want to cut 25mm acrylic, you need a 250W or 400W laser.

CHECK THE LENS OF THE LASER CUTTING MACHINE

Most operators know they need very low air pressure to achieve a polished edge. But they may not know it’s making their lenses dirty. A dusty lens can cause a host of problems for the operator, such as poor focus and reduced laser power. If you want to cut acrylic with polished edges, please check your lenses daily to prevent these problems.

CHECK THE FOCAL LENGTH OF THE LASER CUTTING MACHINE

In order for the laser to cut thick acrylic materials better, it is helpful to adjust the focal length to focus the laser energy. For example, if you want to cut a 10mm or 20mm acrylic sheet, it is best to choose a lens with a longer focal length. Because a lens with a longer focal length spreads out the focus and gives a straighter cut. It makes the beam a bit wider. And it prevents sloped or uneven edges.

CONCLUSION

According to the above content, we know the precautions when cutting acrylic sheets with a laser machine. Before starting the machine, the operator should adjust the power, lens transmittance, and focal length to the best state. Choosing the right cutting method can get twice the result with half the effort. At the same time, doing so can also ensure that the cutting surface is clean and smooth, avoiding the need for redundant processing steps.
