following the computer industry advertising decorative cutting plotter, computer and large format printer after a new development direction - the computer laser engraver has been gradually popular in the market. cutting plotter of the computer is the choice of performance and, the large format printer is the choice of precision and water supplies, as well as the adaptation, then the computer laser engraver choice should pay attention to what is » will be invested in awareness on the investment is ahead of the laser engraver and errors in the choice of buying the product is not suitable for » each investor is voted into the xinku qian, these xinku qian will bring benefits;

here is our opinion, for your reference: we believe that choicelaser engraver should note the following:

1, laser engraver of the category: functions of the computer from the laser engraver divided into low-power laser engraver and high-power laser engraver two categories. low-power laser engraver refers to the electrical power is carving a smaller laser engraver (generally 80-200 w), the electrical power because of its smaller sculptures, each cutting surface can only be applied to less sophisticated processing. for example: xiongpai, sand table model of the surface processing, and other crafts. such high-power laser engraver can not be carried out carving and cutting. high-power laser engraver is carved in 700 w motor power over the laser engraver. not only can this type of laser engraver for low-power engraving, but also a high-power engraving. for example: production of crystal words, all types of advertising signs, sheet metal cutting irregular in shape, the artificial stone processing. because of its great power, can be cut under a 30 mm thick plexiglass or by forming a high-power forming carving knife. some users do not have a clear high-power laser engraver and the power of small points, watched the demonstration of high-power laser engraver, because of difficulties in investment, bought a slightly lower price point of the low-power laser engraver. the results can only be carving each of the xiongpai less than two yuan (some areas only a few cent), the plexiglass plate, and so the power can only watch others carving it. the same investment, the same store costs, the same operation and other staff wages, but 80 percent of the engraving business can do, not only reduced their effectiveness, but also in peer competition in a very disadvantaged position. this is in the choice of laser engraver, it must pay attention to. if you are in this industry application must be able to purchase a high-power engraving of the laser engraver.

second, laser engraver brand: laser engraver of production technology for cutting plotter to be much more complex and different from the laser engraver cutting plotter of the many, and this is a lot of cutting plotter manufacturers very early in the development of laser engraver and has not introduced the product reasons. fine laser engraver requirements, stability, once the uncertainty of the situation will result in serious waste of materials. therefore, the purchase of a strength of the product manufacturers to reduce waste and because of machine malfunctions caused by the possible loss.
third, carefully observe the operation of laser engraver demo: small sculptures can be seen the precision of laser engraver, the sculpture can be seen high-power laser engraver scope of application. if the laser engraver carving koaza the poor accuracy, then a high-power engraving at the edge of a rough time if a high-power carving a more serious resonance (vibration), a laser engraver will also greatly reduce the accuracy. if unable to carry out high-power laser engraver carving, the laser engraver scope of application will be greatly discounted. therefore, based on laser engraver to the presentation of the laser engraver determine the scope of application, which is the scope of your engraving business. laser engraver on the application of direct your decision whether to bring economic benefits.

4, laser engraver supplies and software applications: laser engraver supplies should be very low, the general laser engraver should be able to use ordinary lathe processing tools, the price only a dozen yuan. but some laser engraver all using a special tool, greatly increasing the cost of supplies. the application software is also very important. some brands of laser engraver software failure, the laser engraver can not use other software. other brands of laser engraver can be applied to common software, as long as the new software or a software upgrade features a new, these new technologies we can immediately create a benefit to you.

5, laser engraver control part: laser engraver control of the general divided into two categories. the first category is computer controlled and self-control is only part of power-driven. such laser engraver can not work offline, which is not carved in the course of other computer typesetting work and may be caused by computer errors and waste. the second category is the controller itself to control and drive. this laser engraver can work offline, that is, once the laser engraver start work immediately on the computer typesetting can work. this is actually a computer savings and reduced due to computer errors caused by the operation of waste. this has greatly enhanced the efficiency of the laser engraver.

6, carving on the motor: jiachen optional high-power laser engraver electrical frequency to ensure that the high-power cutting machines, while also take into account the fine processing, cutting power and precision machining work closely together. some domestic brands of laser engraver carving is not reluctant to choose high-power motors, but because of its high-power engraving machine body can not withstand the rigid and can not be used.

Professionals have been using lasers in the process of making all sorts of products, such as signage, for over two decades now. This time frame has seen many changes, but the use of laser techniques, such as laser cutting, laser engraving or laser marking are more and more widely preferred by professionals when they want to provide their customers with high quality products and services.

Laser cutting is typically a thermal process in which the material in a localized area is cut with a focused laser beam. A clean edge is obtained after the molten material has been ejected from the cut by using a co-axial gas jet. Moving the laser beam under CNC control produces a continuous cut.

High power lasers are frequently used in industrial processes, and laser cutting is probably the largest application of all. The range of applications that employ laser cutting is very large, from smaller batch manufacturing and prototyping to continuous production line systems.

Over the past few years, the use of this laser cutting technology has experienced dramatic increase, and its increased flexibility represents an advantage over choosing the more conventional mechanical processes. Laser cutting comes with a series of notable improvements in edge squareness, accuracy, heat input control, etc. This is the reason why laser cutting has gained so much ground over the other profiling techniques, such as oxy-fuel cutting or plasma cutting.

All in all, the benefits of the laser cutting technique can be summarized to the following: it provides a high quality cut, which requires no additional finishing; it can cut virtually any material; it requires no contact, meaning that it leaves no marks; it comes with low heat input, which translates in low distortion; it has enhanced flexibility, for both simple and complex parts; and it can be set up very quickly.

The laser engraving technique uses the same laser beam as tool, which ultimately results in lower costs, as the non-contact mark that the laser produces comes with significantly less wear on tooling. The chances for the product to be deformed and/or damaged are also considerably reduced with laser engraving, as compared to more conventional methods of engraving.

Other advantages of the laser engraving technique include: it produces clean and permanent marks; it provides greater versatility as far as the choice of material is concerned, as it is faster than most other product imprinting methods; the same machine can be used for both engraving and cutting thin materials.

Laser engraving is now performed with highly evolved equipment, as compared to that of the early days of this technique. The constant flow of gas is no longer necessary, as lasers are now sealed. Safety is not an issue anymore, and the machines are considerably simpler to learn, operate and maintain. The evolution of the laser engraving equipment can also be seen in the increased speed of engraving, as well as in the more numerous features they have. And above all, laser engraving equipment is operated by means of computer technology, which is probably the most important change of all.

All in all, the laser equipment used nowadays is easy to learn, operate and take care of, as well as more affordable and feasible to many people. In other words, all these laser technologies can make a great difference to your business.
