    The Use Of Lasers



    Advanced industrial lasers have evolved well beyond simple cutting and welding applications. Laser technology now offers an industrial de-coating and surface cleaning solution that is cost effective as well as responsive to environmental concerns. From the automated cleaning of molds to precise de-coating to oxide removal, laser surface treatments are proving to be an attractive option to traditional labor-intensive methods. In the past decade laser paint removal and cleaning systems have generated significant interest as a viable alternative to conventional cleaning and paint removal technologies.http://www.lasermarkingcnc.com Research on mobile, reliable, and powerful laser systems for cleaning and paint removal operations began in the late 1980s with the modification of welding or cutting lasers into laser systems for surface preparation. This approach did not meet the requirements for surface preparation, which are significantly different than for cutting and welding. In the early 1990s, research took place around the world for more efficient, reliable laser systems for surface preparation work. It took another few years to develop the technology from experimental laboratory systems to dependable systems capable of use in day-to-day industrial operations. Today, a wide variety of industries have adopted laser systems for a range of surface preparation tasks. Applications include mold cleaning, paint removal, joining pretreatment, oil and grease removal, and many more. Operating principle The laser generates a directed and monochromatic beam of light which typically is tightly focused to create high power density. At the focal point, the energy of the intense laser beam will be absorbed by the contamination or paint layer, thermally incinerating or sublimating the target material, such as paint or contamination (see FIGURE 1). These processes will, in combination with the resulting micro-thermal shockwave, remove the target material as long as the target material is able to absorb the incident laser energy. The better the target material absorbs the energy, the faster it can be removed. Color, chemical composition, and thickness of the target layer all have a direct impact on the effectiveness of the process. The removal process automatically stops once a metal, or otherwise relatively reflective, substrate is reached. Reflective surfaces do not generally readily absorb the laser energy. Any residual heat transfer into the substrate material can be a critical factor. To minimize this effect, many laser equipment manufacturers use pulsed laser sources. The beam intensity (laser power per beam spot) is a critical parameter for the heat transfer into the substrate material. Very short laser pulses with a pulse duration of only a few nanoseconds (ns) in combination with a very small focus diameter (0.02 in) or longer pulses in the millisecond (ms) range with a larger focus diameter (0.2 in) result in a minimal heat transfer into the substrate material. Under normal operating conditions and with the right process parameters, damage to the substrate material can be avoided. The heat transfer factor of continuous-wave laser systems is much higher and might result in substrate temperatures that will damage the substrate. Test results with a handheld pulsed Nd:YAG laser with an average laser power of 500W (peak power of more than 400kW) on an aircraft aluminum sheet resulted in maximum substrate temperatures of 170 °F. Pulsed laser systems generate laser power levels well beyond the average power of the laser source. A pulsed 150W solid-state laser will generate a peak pulse power of more than 160kW.http://www.lasermarkingcnc.com This high peak power and the above mentioned beam parameter result in a power intensity removing many target materials with acceptable production rates. Currently, there are three different kinds of laser sources available for surface preparation works. The main difference is the laser beam generation and the resulting beam delivery configuration.

    The Advantage Of Fiber Laser



    Development of laser technology range is beyond what we can imagine. Nanosecond laser, the microchip laser, and us to the femtosecond laser had made great contributions to the cause of science and medicine. But a special laser stand out, it's fiber laser. In the past couple of years,the production of this top class laser has increased by up to 300% annually, which gives testament to their efficiency compared to the likes of Carbon dioxide lasers, which are predominantly less effective. The fiber laser has proven invaluable in folding metals, welding and cutting backing a potent punch in its high optical contact beam that gives a clean,http://www.lasermarkingcnc.com precise cut with the slightest of efforts. This fiber laser is coming at the very opportune time. Many large scale industries are now becoming aware of the need for effective lasers, and that is trickling down to improved production and overall growth in terms of operational capacity. The fiber laser is a technological milestone-one that will cause a revolution in the manufacturing industry and bring the kind of value that has been lacking over the years. When you think about the kind of versatility you get with this laser, coupled to the fact that it has substantially lesser carbon dioxide emissions; then what you get is a solid state laser that is both effective and environmentally friendly, which is more than can be said for its competitors. Fiber lasers are tipped to be a major contributor to technological growth in the very near future, and they are expected to change many industries for the better. The adoption of solid state laser is also set to replace other less effective lasers, and to benefit many different sectors both in business and other relevant industries. New technology is beginning to shift the proverbial posts,http://www.lasermarkingcnc.com and to redefine our approach to emerging trends. Fiber lasers are a promising new investment, both as an eco-friendly tool, and an impressive industrial innovation.

    Introduce some different types of fiber laser marker



    There are many types fiber laser marker to satisfy different indutries. Today I will share with you 4 types fiber laser marker, as following: 1. Desktop type This type uses widely.http://www.lasermarkingcnc.com It equips desktop industrial PC, so it has a bigger cabinet. If you have a big workshop, and your product size is not big, not very heavy, then choose this type. It's practical. 2. Mini type Mini type also is the one of most popular models because its samll size. It will save users' floor size, but also save freight if you choose to delivery by air (by DHL/Fedex/TNT express). The only difference between desktop type and mini type is desktop type equips desktop PC while mini type equips laptop. All core spare aprts assemble in a small cabinet(the left part in the photo), so it will save space, also it's easy to move. 3. Portable type Portable type is more easier to move or put in different places. Net weight only 35KG, easy to carry. Now it's the smallest laser marking machine in market. Desktop and mini type adjust focal length though lifting column and rotating handle, but portable type adjust focal length by 3D worktable. you can rotate screws get work table left-right-up-down. Another way, you also can put machine on a higher table, then put your product on a lower table to adjust focal length, then mark your product. Another advantage is portable type also can mark heavier and bigger products. Before that,http://www.lasermarkingcnc.com you need take 3D work table off, then put machine in a proper position. 4.Enclosure type. Enclosure type-very popular in Europe market. It can protect operator's safety. User can set"marking only close the door". But this type also expensive than other types. Besides, this type adjust focal length by press button. It's automatic. you may press "up" or "down" to adjust focal length.

    How Do Laser Marking Machines Work?



    Although, there are a number laser marking machines available of in the market, the latest state-of-the-art technology used widely is the fiber laser machine. This machine is the best option existing that uses fiber-pumping technology to “dope” fibers with a unique earthy element like Ytterbium. Using this element (Ytterbium) in a laser marking machine increases the ability of fibers to carry high-emitting diodes,www.lasermarkingcnc.com which are pumped to optical heads through the fibers. At this point, the light beam expands to produce the capability of laser marking. The light beam is then able to mark a variety of materials using any one of the following four methods: 1. Removal of a layer of any material or Ablation 2. Etching of material surface to change color or Carbon Migration 3. Bonding 4. Laser Engraving Laser marking applications are suitable with a several material types. These can range from leather to plastics and metals as well. The different kind of metals that fit perfectly to the fiber laser engraving criteria include silver, bronze, gold, stainless steel and platinum. Other materials and elements that respond positively to fiber laser marking include copper,www.lasermarkingcnc.com aluminum, carbide, tungsten and medical grade alloys. Different Ways That Laser Marking Machines can be used A fiber laser marking machine that uses fiber lasers is also known as a laser engraving machine due to the resulting surface patterns produced during the ablation process. The laser machines are used for an array of applications including:Jewelry Engraving,Laser Cutting and Medical Devices& Equipment
