When you need to cut thick materials like 20mm acrylic or wood on co2 laser engraving cutting machine, you should use high power rate and very slow cutting speed. If you work on normal table, the material bottom will be reflected by laser so as to a bad cutting result. Even we use the honey comb table, it also has some reflects on the material. However, with the help of aluminum blade cutting table of Thunder Laser wood laser cutting machine, you can adjust the density of the aluminum blade according to the size of the object, so that the object would be hung up in the air which can reduce the influence of the reflection of laser and bring you a much better cutting result.
