Features: 1. Thickened all-metal structure: All-metal structure, high-precision CNC machining, high flatness, firm structure, not easy to deform, not easy to offset. 2. Rapid heat dissipation: The size of the honeycomb has been scientifically calculated, so that the engraved object can be rapidly dissipated during the engraving process, and the cutting edge is finer, and at the same time, it can prevent the engraved object from burning due to excessive temperature. 3. Non-slip metal fixture fixation: The fixture design is suitable for fixing carvings of various sizes, preventing objects from shifting to the exact position during the carving process, and preventing the carvings from being deformed. 4. Quick measurement: The X-axis and Y-axis have high-definition and precise scale lines, forming a ruler, which is convenient for you to quickly measure the size of the engraved object. 5. Double protection desktop: ATOMSTACK honeycomb board is designed with scientific and reasonable honeycomb height and size to prevent laser burning of the workbench or desktop. At the same time, it is equipped with an anti-cutting metal protective pad, which can further protect the desktop from laser damage. It is very suitable for various styles of CO2 or diode laser engraving machines. 6. Protect the laser module: In the laser cutting operation, using the ATOMSTACK honeycomb board can prevent the laser reflection from damaging the laser head during the cutting process and prolong the service life of the laser. 7. Applicable equipment: CO2 laser engraving machine, diode laser engraving machine, fiber laser engraving machine. 8. The effective protection area is 400*400mm. 9. Perfect fit for 410*400mm frame type machines.
