Metal laser cutting machine refers to the CNC laser cutter specially used to cut and process metal materials. And it mainly includes stainless steel laser cutting and sheet metal laser cutting. Besides that it also includes copper, aluminum, carbon steel, iron, aluminum alloy, and various metal alloys.

The sheet metal laser cutting equipment mainly consists of two parts, one is the CNC console, the other is the machine tool. The users can input the drawings for processing through the CNC console. And the console will transmit the instructions to the processing machine tool. Such a machine tool will process the desired metal pattern according to the instructions.

The central part of the machine tool is mainly the laser generator, which is the core of the whole equipment. Because it is the device for cutting metal. It can convert electrical energy into light energy and release a super-strong laser beam. And the laser beam has a lot of energy. By irradiating on the surface of the sheet metal, the surface quickly reaches a high temperature. And the irradiation surface of the work-piece becomes melting and evaporating. In this way, it realizes the purpose of cutting and engraving through the movement of the cutting head. 

Fiber laser cutting machine is a kind of CNC laser cutter which is the commonest metal cutter in manufacturing industry. It creates a high-energy laser beam and penetrates the dick metal sheet. The laser wavelength decides the dick of metal it will deal, and the scope of laser wavelength is about 1060-1080nm.

· Working principle:

The metal laser cutting machine uses the laser beam emitted from the laser generator to focus into a high-power density laser beam irradiation condition through the optical path system. The laser heat is absorbed by the work-piece material, and the work-piece temperature rises sharply. After reaching the melting point, the material begins to melt and vaporize. In addition, the high-pressure gas coaxial with the beam directly blows off the molten metal. And the machine cut through the metal material and form a very small hole. Along with the movement of the laser head, numerous small holes appear and connect to be the outline of cutting.

Because the frequency of laser cutting is very high, the connection of each small hole is very smooth. And the product after laser cutting has a high degree of finish. This shows that the laser cutting process is essentially different from the machining of the machine tool.

· Working features:

The laser cutting machine replaces the traditional mechanical knife with an invisible laser beam. Therefore, it will not scrape or damage the working surface during work. The laser cutting speed is fast, and the incision is smooth and flat without shearing burrs. Generally, it does not require subsequent processing. The heat-affected zone during the cutting process is also small. 

The work-piece has no deformation, and there is no mechanical stress on the incision. The sheet metal laser cutting equipment reaches high processing accuracy and has no damage to the material surface. Through CNC programming, the machine can process any kind of plane design. And it can cut the whole piece of metal sheet with a larger size. No need for opening the mold, the metal laser cutting machine is really economical and time-saving.
