Fiber laser is a laser cutting machine is the core component, in general, it has played a significant effect on the cutting laser cutting machine. When choosing laser cutting machine, fiber laser customers are very focused brand, even the life of the module integrated manner. Well, today on the high-energy 30000mw laser pointer to tell you about the fiber laser modules.
Fiber laser modules are divided into single-mode and multimode, in cutting applications, a focused spot has a great influence on the cut quality, relatively small core single-mode lasers, beam quality is better than multi-mode, energy distribution Gaussian distribution, the highest energy density in the middle, three-dimensional figure is a sharp mountain-like circle.
Multimode lasers compared to thicker core, single-mode beam quality to be worse compared to the distribution of energy as compared to the average number of single-mode light spot, a three-dimensional image inverted cup from the edge steepness of view, than multimode many steep single-mode.
1mm sheet cutting speed multi-mode single-mode than 20% higher, the visual effect is almost, but 2mm start, the speed advantage of the gradual decline from the beginning of 3mm, both speed and effect, the advantages of high-power multimode green laser pointer speed and effectiveness is very obvious It reflected. So the advantages of single-mode in the sheet, multimode advantages planks, single mode and multimode not mutually comparable value, is a fiber laser configuration, like a car, cars for the road, suitable for cross-country mountain but cars also run mountain, cross country and road run, so choose multimode fiber laser in the end depends on the actual end-user or single-mode processing needs.
So single-mode and multi-mode, how do we choose?
High Energy Laser suggestions: differentiate from the power level, the lasers 1000W or less because of the energy itself is not high, mainly in favor of the sheet processing of material thickness, and therefore within the single-mode 1000mw green laser 1KW configuration is in line with the actual market situation, more than 1KW of power to take into account the laser Bohou. From the entire industry in terms of processing, improve processing quality is a rigid demand, is not compromise, so a lot of high-power single-mode laser selection will not be considered to be the quality assurance process for the first!
At the same time, the single-mode core is generally smaller, which means the same power of the laser light energy transfer in which single-mode core carry more, the material is a challenge, but when cutting highly reflective material, high intensity reflection laser light emitted overlay, if the fiber material is less than the tolerance will be very easy to "burn core", while the core material life is also a challenge! So many laser manufacturers in the high-power fiber 500mw green laserconfigurations still use multimode Configuring!
Laser Marking Machine Marking Process Classification
According to different materials, different wavelengths of laser light absorption different characteristics, the general laser marking machine is divided into two categories, one is the use of a YAG laser, suitable for processing metal and most non-metallic materials such as iron, copper , aluminum, gold, silver and other metals and various alloys, and ABS material, ink coating, epoxy resin and so on. Another use CO2 laser 5000mw, only the processing of non-metallic materials, such as wood, paper, acrylic, glass and the like. Some materials applies to both types of laser marking machine, but the process will be different effects identified.
YAG laser marking machine includes a lamp-pumped, semiconductor and fiber three categories, CO2 marking machine includes a radio frequency tube and the glass tube into two categories, the five products constitute a laser marking machine standard model. The actual needs of different users, with different shape structure, fixture tooling, tailor-made software systems, constitute a complete laser marking solutions.
With respect to the pneumatic marking, electrical corrosion, marking the traditional way of screen printing, inkjet printer, engraving machine, laser 3000mw marking has the following advantages:1. The laser processing optical contact with the non-mechanical contact, no mechanical stress, it is particularly suitable for high hardness (such as carbide), high brittleness (such as solar wafers), high melting point and high precision (such as precision bearings) special requirements high and other occasions.
2. The energy density of the laser processing of large, time is short, small heat-affected zone, heat deformation small, heat stress and will not affect the internal electrical performance. Especially 532μm, 355μm, 266μm laser cold, special materials for precision machining.
3. direct laser ignition etched a permanent mark, can not be erased, the deformation will not fail to fall off, for Anti-forgery, and product traceability requirements.
4. The 1000mw green laser processing system itself is a computer system, you can easily arrange, modify, there are skip, random code and other functions, to achieve unique product coding requirements, suitable for personalized processing, small batch processing of multiple batches more We have an advantage.
5. Mark the effect of fine, beautiful technology, high accuracy, improve product quality, increase product added value. Width can be as small as 10μm, depth of up to 10μm or less, and can "millimeter" parts of the surface size of the labeling.
6. Low supplies, non-polluting, energy-saving and environmental protection, in line with European environmental standards, in line with the GMP requirements of the pharmaceutical industry. Low processing costs. One-time investment in equipment is more expensive, but continuous, large number of processing and finally to each part of the processing costs down.
7. The flexible processing methods. Through a transparent medium on the inside of the workpiece processing, easy to guide, focus, direction to achieve transformation, easily and with CNC systems.
