Features ESSENTIAL ACCESSORIES FOR LASER CUTTING After using the laser cutting workbench to cut wood, acrylic and other materials, the edges of the wood are neat and clean, and will not yellow easily due to smoke, and a clean cut can be achieved. All-metal and high flatness: the honeycomb panels are all made of metal and are processed with high-precision CNC. The structure is firm and not easy to deform, and the flatness is high. The perfectly sized work area of 400 x 400 mm fits well in most common laser engraving machines to maximize the cutting area. 3 Average Design for Observation: Honeycomb panels feature a very practical cutting and observation design. When the laser cuts wood or acrylic, the metal backing plate at the bottom of the honeycomb panel lights up brightly, which means the cut has penetrated. It solves the problem that it is difficult for ordinary engraving machines to judge whether it is cut. Safety Metal Desktop Protection Plate The honeycomb panel is equipped with a metal desktop protective plate, which can protect the desktop from laser damage, perfect for small DIY diode lasers. RIGHT ANGLE MEASURING RULER There are precise scale markings on the X and Y axis, forming a right angle measuring ruler, which allows you to quickly measure the size of the engraving object. Wide compatibility: the machine is compatible with various mature engraving machines, such as Diode DIY laser engraving machines and CO2 laser engraving machines.
