Laser marking machine principle: Semiconductor laser marking machine is the use of galvanometer laser marking technology and the most advanced semiconductor pump laser technology. The United States imported semiconductor array. A semiconductor diode Nd: YAG crystal YAG rod is a lot of reverse particles are formed under the action of the giant Q-switch pulse output wavelength of 1064nm, the laser beam through the beam expander, focusing finally achieved by controlling the deflection of the galvanometer standard engraved. Marking Features: High-speed, non-contact, there is a certain depth, marking directly through the computer. Most suitable for metal and nonmetal. Typical applications: bearings / Chip / faucet / ring / frames / piston / crafts / souvenir / mobile phone keypad / watch / stainless steel cutlery / drill / carbide tools / stainless steel mug / electrical panel / meter disk / U disk / computer Keyboard / medical equipment / communication products, jewelry and so on. Suitable material: any metal (including precious metals), engineering plastics, electroplating materials, coating materials, coating materials, plastics, rubber, epoxy resin.
