The laser marking machine is mainly used for laser engraving, etching or cutting on the surface of materials, the marking machine is controlled by a computer, is compatible with different graphic and text formats, and has high-speed data processing capabilities, its working method is non-contact, and no external force is exerted on the material to be processed. The workpiece is easily fixed and does not deform, the laser beam is focused to produce a high-energy, high-quality fine spot, which reacts with the material to be processed to melt or vaporize, powerful software processing capabilities include up to 7 layers of engraving matrices , the depth of the pattern is controllable, laser is known as the "green" and "flexible processing tool in the 21st century, it is environmentally friendly and energy-saving, and is a clean energy source.
