The people rise of laser welding machine

The quality of the laser welding machine how to judge? 1, roughness of laser cutting section would be a vertical line, texture depth decided to cut the surface roughness, the lighter line, cutting section is more smooth. Edge roughness affects not only the appearance, also affect the friction characteristics, in most cases, the need to reduce the roughness of texture, so the more shallow, the higher the cutting quality. 2, if the thickness of the metal plate more than 10 mm, vertical cutting edges is very important. Will look from the focus, the laser beam divergence, according to the location of the focus, at the top or bottom width of the cut. Deviate from the vertical line % mm, edge trimming is vertical, the higher the quality. 3, incision width generally does not affect the cutting quality of incision, only special precision contour is formed within the equipment, it has important influence on cutting width, this is because when cutting width determines the thickness increase, the minimum outline, cutting width has been increased. So I want to make sure that the same precision, no matter how much the laser cutting machine processing area of the kerf width and artifacts should be the same. 4, the line of high-speed cutting board, molten metal not be perpendicular to the laser beam under cutting, but after the laser beam deflection. As a result, the bending line formed on the cutting edge, texture closely follow the movement of laser beam, in order to correct this problem, reduce the feed speed of cutting side effects, laser cutting, a very important quality factor can be determined, greatly eliminate the formation of lines. 5, burr. Because of the need to remove excess burrs, so judge the number of burr and to judge what is the extent of the cutting quality of the laser cutting machine. You also need to pay attention to? That is the metal laser cutting machine price is too cheap not to buy, the small power cutting machine general price on market from 200000 to 1 million, high power prices in 1 million to millions. If the price is too low, there will be problems, suggest you still don't buy, because every company wants to make money, not less than the cost of the product price to sell. Look at the old and new. If used laser cutting machine, suggest or not to buy second-hand, because there is no guarantee of quality, the follow-up maintenance cost is higher, if the machine often bad, not only affects the production efficiency, also increased the cost of production, to the enterprise, is not worth the cost. Laser cutting machine in use after a period of time, there will be some problems. If there is no professional and technical personnel to repair it, it is difficult to solve. So I need laser cutting machine manufacturers to provide customer service support. So there is no customer service, suggest not to buy. For laser cutting machine laser cutting machine has the advantage of processing sheet metal parts is greatly increased the labor productivity of advanced equipment, high precision parts processing, processing cycle is short, without the traditional complex steps, such as stamping mould replacement, so more and more equipment manufacturing enterprises begin to use. Laser cutting is a laser beam focus lens will focus on material surface, at the same time with coaxial laser beam of reducing gas blow away the molten material, let the laser beam and materials along a certain path of relative motion, thus forming a certain shape of the slit. Laser cutting technology is developing rapidly, the application scope is more and more widely, is an advanced processing method, especially suitable for cutting steel plate cutting technology. Laser cutting machine is obvious advantage is: good cutting quality, incision narrow width ( As a general rule, be 0. 1 to 0. 5毫米) , high precision, General center distance error is 0. 1 to 0. 4 mm, the size of the shape error is 0. 1 to 0. 5毫米) Good, the surface roughness of the incision ( 12. 5 ~ 25 meters) , and generally do not need to deal with, can be welded. Cutting speed, such as 2 kw laser power, 8 mm thick carbon steel plate cutting speed is 1. 6 m/min, the cutting speed of 2 mm thick of stainless steel meters/minute, small heat affected zone, the deformation is small. And clean, safe, no pollution.
