How to Laser Cut Acrylic?
Many friends have reported to us that it is very troublesome to cut acrylic, and it is prone to problems such as uneven cutting surface, strong concave and convex, white cutting edges, and melting edges caused by reflection of honeycomb panels. What should we do?
Compared with the usual cutting of plywood, the cutting of acrylic does not seem to be as simple as imagined, and it is not necessary to follow the cutting parameters of the wood to achieve the best results. In order to cut the acrylic to be flat and smooth, the edges are not whitish and the honeycomb panel is not reflective, we have made a simple analysis of this acrylic cutting test below.
1. The power is set to 65%-70%.
The minimum power and maximum power are set because the speed when cutting straight lines is faster than cutting corners. We said that the faster the speed, the shallower the cut. Therefore, in order to be able to cut the sample through, we usually set the minimum and maximum power.
2. The speed is set to 5mm/s.
We all know that the faster the speed, the higher the processing efficiency, so we will increase the power as much as possible to increase the speed when cutting general materials, but acrylic is different, too fast speed will make the cut surface uneven and uneven. sense, so in order to cut out a smooth effect. We need to keep in mind when setting the parameters: increase the power, reduce the speed.
3. Do not blow air when cutting.
When many people cut acrylic, they will have the problem of white cut surface. This is because they use air blowing when cutting, so if you want to cut a smooth effect, please turn off the air blowing. When cutting acrylic without blowing air, please be sure to guard it. Because there is no flame retardant with strong air blowing, the material is easy to catch fire during the cutting process. If you find a fire, please turn off the machine in time.
4. Overhead cutting.
When cutting acrylic, if we want to avoid the edge fusion problem caused by the reflection of the honeycomb panel, we can solve it by overhead cutting.
