The Introduction of 4000W Laser Cutting Machine in detail

  • news

Laser cutting process is the use of invisible light beam instead of the traditional mechanical knife, with high precision, cutting fast, not limited to cutting pattern restrictions, automatic layout to save material, smooth kerf, low processing costs, etc., will gradually improve or replace the traditional metal cutting process equipment. The laser cutting machine is more and more important in industrial production, so today this article will write a detailed introduction of the 4000W laser cutting machine. The Working principle of laser cutting   Laser cutting may be quite non-contact processing with high energy density and good controllability. It uses the beam emitted from the laser generator to focus the beam into a spot with a minimum diameter of but 0.1mm through the optical path system, to realize high power density beam irradiation conditions. After the warmth of the laser is absorbed by the irradiated workpiece material, the workpiece temperature rises sharply and reaches the freezing point. the fabric begins to liquefy and form holes, and with the high-pressure airflow, with the relative position of the beam and therefore the workpiece moving, the fabric finally forms an endless slit. To accelerate the melting of the fabric, blow away the slag and protect the cutting seam from oxidation, it's necessary to feature auxiliary gas suitable for the fabric to be cut, to realize excellent cutting speed and cutting quality. At present, the common cutting methods mainly include straight cutting, wire cutting, profiling cutting, flame-cutting, water jet cutting, laser cutting than on. Among them, laser cutting is more and more widely utilized in steel plates under 16mm due to its… Read More »The Introduction of 4000W Laser Cutting Machine in detail

Part 1: What Is A Siber Laser Cutting Machine? A fiber laser cutting machine is a laser emitted from the laser, through the optical path system, focused on a high power density laser beam. The laser beam irradiates the surface of the workpiece, causing the piece to reach its melting or boiling point, while a high-pressure gas coaxial to the beam blows the molten or vaporized metal away. With the relative position of the beam and the workpiece moving, the material is eventually cut to form a slit, thus achieving the purpose of cutting. Part 2: How Does a Fiber Laser Cutting Machine Work? The fiber laser cutting machine has great power to fulfill the cutting effect. This cutting technology is progressing in sophisticated ways. Laser cutting is the laser beam irradiation to the surface of the workpiece when the energy released to make the workpiece melt and evaporate, to achieve the purpose of cutting and engraving, with high precision, cutting fast, not limited to cutting pattern restrictions, automatic typesetting to save material, smooth kerf, low processing costs, etc., will gradually improve or replace the traditional cutting process equipment.   Part3: What Components Made up the Fiber Laser Cutting Mashine?

Precautions for correct use of fiber metal laser cutting machine

When we use the fiber metal laser cutting machine, some dust is often generated which affects the eyes. For the sake of safety, we suggest that dust removal equipment must be installed, which is good for people's health and machines. It is recommended that you master the following three points, which can protect your body. 1) The laser is invisible, and the laser beam is invisible to the naked eye. If you open the hood for maintenance, you must pay attention. Don't accidentally touch the light path. It is more dangerous to touch the light path. 2) The harmful elements (znse) in the focusing lens of the fiber metal laser cutting machine should not be in frequent contact with the lens, and the scrapped lens should be specially disposed of, and not littered. 3) Everyone pays attention to the material when processing, if it is carbon steel or stainless steel, there is no problem. If a large amount of aluminum alloy is processed, the cutting dust will be suspended in the air, which is harmful to the human body after inhalation. Also, when cutting aluminum plates, the light is very reflective, and the cutting head needs a protection device, otherwise it is easy to malfunction. According to years of laser equipment research and development experience, laser cutting is much more environmentally friendly than plasma cutting and flame cutting. There is… Read More »Precautions for correct use of fiber metal laser cutting machine

The technical process of laser cutting machine fiber

There are two technical processes for laser cutting machine fiber : One is that pulsed lasers are suitable for metal materials. The second is that continuous laser is suitable for non-metallic materials, and the latter is an important application field of laser cutting machine fiber technology. Several key technologies of laser cutting machine fiber are integrated technology of light, machine and electricity. In the laser cutting machine fiber, the parameters of the laser beam, the performance and accuracy of the machine and the CNC system all directly affect the efficiency and quality of the laser cutting. Especially for parts with higher cutting accuracy or larger thickness, the following key technologies must be mastered and solved: Focus position control technology. One of the advantages of laser cutting machine fiber is the high energy density of the beam, generally 10W/cm2. Since the energy density is inversely proportional to the area, the focal spot diameter is as small as possible to produce a narrow slit; at the same time, the focal spot diameter is also proportional to the focal depth of the lens. The smaller the focal depth of the focusing lens, the smaller the focal spot diameter. However, there are spatters in cutting, and the lens is too close to the workpiece to damage the lens. Therefore, the focal length of 5"~7.5" (127~190mm) is widely used in general high-power CO2 laser cutting machine… Read More »The technical process of laser cutting machine fiber
