Laser cutting machine industry has developed quite rapidly in recent years. From the initial YAG equipment and CO2 equipment to the current fiber, from low-power fiber to the current 10,000-watt fiber, which shows that our blue laser pointer technology continues to improve, and now the price of laser cutting equipment compared with previous years To be much cheaper, this is a very delightful thing for friends who want to buy equipment, no matter what the industry can afford the laser, afford to use the laser.
For the majority of customers, the purchase of equipment will shop around, so the competition among peers is bound to be ultimately! Nothing more than the concern of people who buy equipment, in addition to configuration, is the price and after-sales service, which is also the competition of major manufacturers. Price competition, the most common peer competition. When you consult the same piece of power equipment, there may be tens of thousands or even hundreds of thousands of price difference between the price. When it comes to configuration and technology, many people might say that the lasers are all for others, and for those of you who are just assembling them together, you do not need any technology at all. Yes, in appearance, this is indeed the case. So many people think that the green laser pointer cutting machine industry threshold low, high profits, just a few people can pull a few. However, how much is done and how much is sold.
Grasp the rules of laser cutting machine processing factors on the processing of surface quality, you can find ways to improve the surface quality of the process measures to improve the quality of the processing surface. When the laser is cutting the sheet at high temperature, the traces of the molten material do not appear in the notch below the vertical laser beam, and instead, it is ejected at the rear of the laser beam. As a result, the curved lines are formed at the cutting edge and the lines closely follow the moving laser beam. In order to correct this problem, the feed rate is reduced at the end of the cutting process and the formation of lines can be substantially eliminated.
The cutting width generally does not affect the quality of the cut. The cutting width has an important influence only when a particularly precise profile is formed inside the part because the cutting width determines the minimum internal dimensions of the profile. As the thickness of the plate increases, the cutting width also varies with Increase. So you want to ensure that the same high precision, regardless of the width of the incision, the workpiece in the high power laser cutting machine processing area should be constant; when the material thickness of more than 18mm, the cutting edge of the verticality is very important; away from the focus, the laser The beam becomes divergent, depending on the position of the focus, the cut becomes wider toward the top or bottom. Cutting edge deviation from the vertical line a few millimeters, the more vertical edge, the higher the cutting quality.
The heat-affected zone refers to the laser cut where the area along the incision is heated. At the same time, the structure of the material itself changes. For example, some materials can harden. Heat affected zone refers to the regional structure of the internal structure changes due to high temperature; and depression and corrosion of the cutting edge of the surface has an adverse effect on the appearance of laser cutting machine. They appear in the general should avoid the cutting error; Finally, if the cutting makes the part heated rapidly, it will be deformed. This is especially important in fine workmanship, where the contours and tabs are usually only a few tenths of a millimeter wide. Controlling laser power and using short 500mw laser pointer pulses can reduce the risk of heat build-up and avoid distortion.
As said above, there are many manufacturers, the equipment sold out is very cheap, of course, with spare parts and machine tools are poor. Such manufacturers generally do not have a long-term strategic plan of sustainable development, there is no core technology. What they do is some low-end things, simple assembly is also OK, if they let them study some high-tech stuff, there is no professional talent, to give him the same configuration of components, they also create good equipment. In addition to a laser device, the machine tool is also important, the same laser, different manufacturers to make the device, and some can use for years without any major problems, but some day-to-day problems.
