1。 The laser cutting machine will focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam shines on the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. Laser gas
2。 Compressed air (generally used to protect the optical path, and some manufacturers also use it to make protective gas)
3。 Auxiliary gas (i.e. gas from the cutting nozzle of the cutter)
The laser cutting machine uses different auxiliary gases to cut different materials. The pressure and required flow rate of the auxiliary gas vary with the thickness of the cutting material.
The purity of oxygen for cutting carbon steel is generally required to be 99.5% or higher. Its main function is to help burn and blow away the cut melt. The pressure and flow rate of each laser cutting machine manufacturer are different, which is closely related to the size of the cutting nozzle model and the thickness of the cutting material plate. The pressure is generally required to be 0.3 ≤ 0.8 MPa, and the cutting port is generally 0.0 2~0.05 MPa. It is difficult to say the flow rate, such as cutting 22 mm carbon steel, and some manufacturers use nitrogen to cut stainless steel, with a flow rate of 10 M3/h (including the double-layer nozzle for oxygen protection)
The laser cutting machine will focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam shines on the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. Optical fiber laser cutting machine is a laser cutting machine that uses the optical fiber laser generator as the light source. Fiber laser is a new type of fiber laser developed internationally that outputs high energy density laser beam and gathers on the surface of the workpiece to melt and vaporize the area on the workpiece illuminated by the ultra-fine focus spot instantly. Automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system. The purpose is to prevent oxidation and blow away the melt. The purity of nitrogen is required to be very high (especially for stainless steel greater than 8 mm, which is generally required to reach 99.999% purity). The pressure is relatively high, which is generally required to be greater than 1 Mpa. If the stainless steel to be cut is greater than 12 mm, or the thickness reaches 25 mm, the pressure is higher, which is more than 2 Mpa. The flow varies depending on the type of nozzle, but it is very large. For example, when cutting 12 mm stainless steel, some manufacturers require cutting 150 m3/h and cutting 3 mm, as long as the flow is less than 50 m3/h.  2。 Compressed air (generally used to protect the optical path, and some manufacturers also use it to make protective gas)
