CNC Wood Router And Laser Machine Work On Acrylic
Acrylic is a very common engraving and cutting material. It is easily be engraved and cutted to any shape and size with lower cost. There are two process for acrylic production. Pouring and calendering. Laser engraving machine usually use the acrylic with pouring process. The frosting result of pouring acrylic after engraved is very obvious. The calendering acrylic is still transparent after engraved. So if you use acrylic on laser machine, please ask the supplier that need the pouring acrylic.
Usually we use back engraving way for acrylic engraving, this cause the acrylic have a three dimension. Please create image before back engraving and speed is high, power is lower. If the power is higher, may cause the uneven engraving path, if you hope engrave the surface deeper, could ask the laser beam to go several paths. Then use fire polisher, then filing color. The color is un-homogeneity if without fire polisher treatment. Laser machine can work for flat engraving, cnc wood router can work for relief sculpture on acrylic vividly. Suggest you use acrylic special engraving cutter for no powder stick and quickly removing.
If the end user is without high requirement, acrylic can be delivered once cutting completed, and no need fire polisher treatment. Or, you need air compressor device for improving cutting edge quality. OMNI laser cutting machine can cut 30mm acrylic with high quality cutting edge. Please notice that the operator of laser machine should be around laser machine while cutting, because there may cause fire while cutting. If you use cnc wood router to cut acrylic, the speed will be rather high, and edge will be also smooth, just not smooth as the laser machine cutting.
Use wet cloth to clean the surface of acrylic.
Use acrylic paints, other paints may damage the surface finishness of acrylic.
