Large surround laser plate cutting machine is a laser processing machine used to cut the plate into the desired shape of the workpiece, the following will be introduced from its structural characteristics, working principle, performance advantages, application fields and other dimensions:

Structural characteristics
Enclosed structure: fully enclosed design, equipped with sheet metal cover and side door, can isolate the laser, the dust generated in the cutting process and the processing structure from the operator, effectively prevent the laser from causing harm to the human body, reduce the smoke escape to the working environment pollution and harm to the operator's body, reduce the risk of mechanical accidents.
Switching table: Many large enveloping laser flat cutting machines are equipped with dual switching tables, such as high-low switching tables. Two cutting table through the chain transmission device to achieve automatic exchange, exchange time is short, generally can be completed within 15-30s, in the cutting at the same time can be loaded operation, save loading and unloading time, improve processing efficiency, save labor costs.
Gantry structure: gantry structure is usually used, gantry beam on both sides are symmetrically installed with pinion rack and servo motor, to achieve double pinion rack drive, double servo motor drive, to ensure that the beam force balance, synchronous operation, with high stability and motion accuracy, can achieve high-speed, high-precision cutting.

Working principle
Laser generation: High energy density laser beams are generated by lasers, such as carbon dioxide lasers or fiber lasers. These lasers use the principle of stimulated radiation to convert electrical energy or other forms of energy into light energy, producing laser beams with high brightness, high directivity, high monochromatism and high coherence.
Laser transmission and focusing: The generated laser beam is transmitted to the laser cutting head through a transmission system such as optical fibers or mirrors. Optical elements such as the lens in the laser cutting head focus the laser beam onto the surface of the flat material to be cut, so that the laser energy is highly concentrated in a small area.
Material melting and vaporization: When the focused laser beam irradiates to the surface of the flat material, the material absorbs the laser energy, the temperature rises sharply, and rapidly melts and vaporizes to form small holes.
Slagging and cutting: At the same time, high-pressure gas, such as oxygen, nitrogen, etc. is sprayed to the cutting area through the auxiliary gas system to blow the melted and vaporized material away from the cutting area to form the slagging. As the laser cutting head moves along the pre-set cutting path, the material is constantly melted and vaporized, and the slag is constantly blown away, thus achieving the cutting of the plate material.

Performance advantage
High cutting accuracy: The use of high-precision transmission system and CNC system, such as ball screw, helical rack and pinion drive, as well as advanced laser cutting head and capacitance non-contact height automatic tracking system, can achieve high-precision cutting, cutting size error is small, narrow slit, cutting section quality is excellent, smooth slit, no additional post-processing is required.
Fast cutting speed: The application of fiber lasers and the efficient transmission system and control system make the large surround laser plate cutting machine have a high cutting speed, which can quickly complete the cutting processing of various plates and improve production efficiency.
A wide range of processing materials: can cut a variety of metal plates and some non-metallic plates, such as carbon steel, stainless steel, copper, aluminum, galvanized plate, electrolytic plate, brass plate, aluminum plate, manganese steel, various alloy plates, rare metals, etc., can also cut some plexiglass, wood and other non-metallic materials.
High degree of intelligence: equipped with intelligent numerical control system, support a variety of common file formats, can import multiple types of cutting graphics with one click, to achieve automatic edge finding, automatic typesetting, automatic focusing, automatic cutting and other functions, simple and convenient operation, reduce the labor intensity of the operator, improve the processing efficiency and processing quality.

Application field
Sheet metal processing industry: used to cut various sheet metal parts, such as chassis cabinets, power distribution cabinets, ventilation pipes, etc., can achieve complex shape cutting, improve the processing accuracy and production efficiency of sheet metal parts.
Automotive manufacturing industry: can cut auto body parts, chassis parts, automotive interior parts, etc., to meet the automotive manufacturing for high-precision, high-efficiency cutting needs.
Advertising decoration industry: used to cut a variety of advertising words, signs, display shelves, etc., can cut out a variety of exquisite patterns and shapes, enhance the effect of advertising decoration.
Machinery manufacturing industry: suitable for cutting various mechanical parts, such as gears, shafts, flanges, etc., to provide high-precision parts processing for machinery manufacturing.
