When cutting acrylic,some factories use CNC cutting machine while some factories use co2 laser cutting machine.
1. Cutting Edge
Acrylic co2 laser cutting machine can get a very clean edge when cutting acrylic. The acrylic cut no need polish and you can use it directly to your products. CNC cutting machine can cut acrylic,but the edge is not as clean as you want. You need to buy one polish machine and polish it, then use it to your products. It means you need to buy 2 machines.
2. Cutting Speed
The cutting speed of laser cutting machine is faster than CNC cutting machine. Especially for the acrylic under 5mm, you can get a very fast cutting speed if you use co2 laser cutter. The speed can reach 20mm/S. CNC cutting machine can not reach this speed. But CNC cutting machine can do 3D works on acrylic, laser is hard to do 3D.
3. Cutting Thickness
Laser cutter has optional laser powers. 80W can cut acrylic up to 12mm,100W can cut acrylic up to 15mm,150W can cut acrylic up to 25mm,280W can cut acrylic up to 30mm. So, 30mm is the maximum for co2 laser cutting machine. But CNC cutting machine can cut acrylic 40mm or more by cutting many times.
4. Working Method
Co2 laser cutting machine is equipped with glass laser tube. The lifetime of the tube is about 10000 hours. One laser tube can use 2-3 years. CNC cutting machine is equipped with spindle motors and use knife to cut acrylic. You need to change new knife every 5 or 10 days, about this. Co2 laser cutter use water chiller for cooling. CNC cutting machine use water cooling or air cooling. It is optional.
In a word,if you need to cut acrylic under 30mm and want to get a very clean edge, acrylic co2 laser cutting machine is your best choice.
XDLASER produce laser machines since 2007, you can contact XDLASER for details.
Laser cutting acrylic is an exceptionally popular application laser machines because of the high-quality results that are produced.
Depending on the type of acrylic and thickness of acrylic you're working with, the laser can produce a smooth, flame-polished edge when laser cut, and it can also produce a bright, frosty white engraving when laser engraved.
Except the above advantages, acrylic co2 laser cutting machine also has the following advantages:
1、 Good cutting quality: for non-contact cutting, the cutting edge has little thermal influence, and basically there is no thermal deformation of the work piece, which completely avoids the edge collapse formed during material punching and shearing, and the cutting seam generally does not need secondary processing.
2、 It will not be affected by the hardness of the material to be cut: laser can process steel plate, stainless steel, aluminum alloy plate and cemented carbide. No matter what hardness it is, it can be cut.
3、 No damage to the working Hardware: the laser cutting head will not contact the material surface and will never scratch the working hardware.
4、 It will not be affected by the shape of working Hardware: laser processing is very flexible, can process any graphics, and can also cut pipes and other special-shaped materials.
5、 High accuracy: the positioning accuracy is 0.06mm and the repeated positioning accuracy is 0.03mm
6、 Narrow slit: the laser beam is focused into relatively small light spots, so that the focus will reach a high power density. The material will soon be heated to the degree of gasification, and holes will be formed during evaporation.
7、 The cutting surface is smooth: there are no burrs on the cutting surface, and the roughness of the cut surface is generally controlled within ra11.6.
8、 Cutting and processing of non-metallic materials: such as plastics, wood, PVC, leather, textile products, acrylic, etc.
9、 Save the investment of mold: laser cutting does not need to use mold, there is no consumption of mold, and there is no need to repair the mold. It saves the time to replace the mold, thus saving the processing cost and reducing the production cost. It is very suitable for the processing of large products
10、 Improve the speed of new product development: after the product drawings are formed, laser processing can be carried out immediately, and the real objects of processed products can be obtained in a very short time.
In the process of making acrylic crafts, we usually need to use laser cutting to make special-shaped acrylic sheets. What should we pay attention to in the process of laser cutting?
1. Acrylic plate is a commonly used laser plate. It is easy to cut plates of different shapes and sizes. The acrylic plate produced by laser can be directly used for bonding or polishing;
2. When the thickness of acrylic is less than 6mm, cutting with laser machine can be completed quickly. If the thickness exceeds 8mm, the laser speed will be reduced relatively;
3. The acrylic plate cannot leave people near the machine during the laser process, because the acrylic plate will be generated by flame during the laser cutting process.
4. If you always need to cut thick acrylic, please try to buy machine with laser power 150W or 300W in order to get acceptable cutting speed.
5. If you need both engraving on and cut acrylic, the most suitable laser power is 100W.
