The traditional processing methods in the sheet metal workshop include cutting, blanking and bending. Laser cutting manufacturers believe that the blanking process requires a large number of molds, which have the characteristics of less cutting and no cutting. When a product is processed, dozens of molds are usually equipped, and some products may even require hundreds of molds. From an economic point of view, with a large number of molds, the cost of the product will increase correspondingly, resulting in a waste of funds. In order to adapt to modern sheet metal processing, reduce production costs, and improve processing technology, laser processing technology came into being.
With the application of laser cutting machines, sheet metal processing technology has been rapidly developed, bringing a revolutionary concept to sheet metal production and processing. Most plate processing companies that are familiar with and accept laser cutting technology and laser cutting machine equipment, and gradually replace traditional sheet metal cutting equipment (mainly CNC equipment, including shears, punching, flame cutting, plasma cutting, high-pressure water cutting , Etc.) With its advantages of high processing efficiency, high precision, good cutting quality, and three-dimensional cutting unified board processing equipment). Laser processing technology plays an important role in sheet metal processing, improving the productivity of sheet metal processing and promoting the development of sheet metal technology. The laser cutting machine has high flexibility, can greatly shorten the processing cycle, high cutting speed, high production efficiency, improve processing accuracy, and accelerate product development. These advantages are the focus of many manufacturing companies.
The laser cutting machine focuses the laser light emitted by the laser into a high-power density laser beam through an optical system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will form a slit, so as to achieve the purpose of cutting. Laser cutting uses an invisible beam to replace the traditional mechanical knife. It has the characteristics of high precision, fast cutting speed, not limited by cutting patterns, automatic typesetting, material saving, flat cut, low processing cost, etc., and will gradually improve or replace traditional metal cutting equipment. The mechanical part of the laser cutter head has no contact with the workpiece, so it will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, the plate deformation is small, and the cutting gap is narrow ( 0.1-0.3mm); The incision has no mechanical stress and shearing burrs; it has good repeatability and does not damage the surface of the material. The plane drawings can be drawn arbitrarily through CNC programming, and the whole board can be cut in large format. It is economical and time-saving without the need to develop molds. Generally speaking, a laser cutting machine is recommended for carbon steel plates within 12mm and stainless steel plates within 10mm. The laser cutting machine has no cutting force, no deformation, no tool wear, and good material adaptability. Whether it is a simple part or a complex part, it can be laser rapid prototyping and cutting. It can realize automatic discharging and discharging, improve the utilization rate of materials, and achieve good economic benefits.
