Type model GZ-BT501 GZ-BT751 maximum laser power 50w 75w 808nm excitation source semiconductor light source (side-pumped) laser type / wavelength Nd: YAG / 1064nm beam quality <3 <6 minimum character minimum line width 0.2mm 0.3mm 0.015mm 0.018 mm Engraving line speed ≤7000mm / s ≤7000mm / s Repeatability ± 0.002mm marking range 50mm × 50mm ~~ 300mm × 300mm Optional Dimensions 800 × 680 × 1200mm (whichever kind) Power Requirements 220V ± 10% / 50Hz / 20A Q-frequency 0.2-50KHz Cooling Water Power consumed carbon dioxide laser marking machine 1.5kw 2kw Total weight 200kg semiconductor laser pumped solid-state lasers (DPSSL) laser marking works by using large power semiconductor quantum well lasers instead of gas lamp-pumped solid-state laser gain medium crystal resonator is, to produce a new laser wavelength, frequency mixing equipment using crystal cross should produce SHG, THG and other wavelength laser. By design never expected to establish a reinspection, the Ministry of equipment production, process inspection, assembly and commissioning of the entire laser marking finished overall inspection process, procedures and quality standards. Diode-pumped laser marking machine adopts semiconductor laser pump source to do to replace the traditional way of krypton lamp-pumped, with a photoelectric conversion rate, good beam quality, small size, low operating cost, easy to install, high stability, maintenance-free and so on. Closed optical system and cooling system thermostat, making the equipment more stable operation of the machine, the output of the laser spot diameter is smaller, especially for high accuracy and fast marking. Model Features: 1, the use of advanced production technology, compact structure, high precision marking, fill the gaps, product performance reached the international advanced level. 2, high conversion efficiency, performance, reliability, long life, the output beam quality. 3, especially for precision laser marking and micro-machining can print a variety of text, symbols, graphics and bar codes on flat or curved, cylindrical and Flyers. Application: widely used in electronic and communication products, graphics and text markup various auto parts, hardware tools, instruments, eyeglasses and clocks, sanitary ware, plastic surfaces, food packaging, jewelry, precision instruments and other fields. 1, all kinds of metal and non-metal marking and engraving the surface of materials and products, such as stainless steel, aluminum, copper, ceramics, synthetic materials, leather, rubber, metal tools, faucets, clutches, bearings, piston rings, pipe, steel plate. 2, the electronics industry: resistors, capacitors, inductors, crystals, printed circuit boards, integrated circuits, computer keyboards, electric access card, cell phone case, watches, various instruments and control panel laser marking. 3, daily necessities and clothing industry: cosmetics, food, stationery, designer panels, product packaging, colored paper, all kinds of paint products, tobacco, handicrafts and other marking. http://www.guangzulaser.com
