Today, I want to introduce some knowledge about laser cutting machine. Let's have a look!
Advantages and principles of laser cutting machine:
Laser cutting machine is mainly used in the cutting of sheet metal, which is also an important part of sheet metal cutting. Generally speaking, laser cutting machine is mainly metal cutting and non-metal cutting. Many cutting methods are difficult to reach the target mainly because they are inferior in speed and quality, but the laser cutting machine has great advantages in this respect. After cutting, the high precision of the laser cutting machine does not need follow-up processing, which greatly saves time.
The principle of laser cutting machine is to generate laser beam through laser, through a series of transmission of mirrors, and finally focus on the surface of workpiece by focusing mirror, and generate local high temperature at the intersection point, so that the workpiece is melted or vaporized instantly by heating pad to form a slit. At the same time, in the process of cutting, the auxiliary gas of a and B will blow out the slag at the cutting seam, and finally achieve the purpose of cutting. Laser cutting is mainly used for thin plates, and the range of cutting materials is very wide, mainly divided into metal cutting and non-metal cutting. Because of the characteristics of laser, such as high direction, high brightness and high intensity, the laser cutting speed is fast, the machining accuracy is high, and the slit is very narrow, generally without subsequent processing.
To sum up, laser cutting machine in cutting materials, a wider range, cutting accuracy higher. It is cheaper to use.
Cutting mode of laser cutting machine:
Laser vaporization cutting
It is to use high-energy and high-density laser beam to heat the workpiece, make the temperature rise, and vaporize the material into steam in a short time. When the steam is ejected, a cut will be formed on the material, so that the cutting effect is achieved. But the heat of vaporization is very large, so the high-power laser beam should be used when heating materials. The materials used in laser vaporization cutting generally include extremely thin metal materials and non-metal materials.
Laser melting cutting
During laser melting and cutting, of course, the material is heated to a certain temperature for melting, and then the non oxidizing gas is blown through the nozzle coaxial with the beam, and the liquid metal is discharged by the pressure of the gas to form a incision. The energy required for laser melting and cutting is only 1 / 10 of that of vaporization cutting, so it is not necessary to completely vaporize the metal. Generally, the materials suitable for laser melting and cutting are stainless steel, titanium, aluminum and their alloys, which are not easy to oxidize.
Laser oxygen cutting
Laser is used as preheating heat source for laser oxygen cutting, and active gas such as oxygen is used as auxiliary gas for cutting. After the gas is ejected, the gas and metal will react with each other to release a large amount of oxidation heat. At the same time, the molten oxide and molten substance are blown out of the reaction zone to form a notch in the metal. Generally, the materials suitable for laser oxygen cutting include carbon steel, titanium steel and heat-treated steel which are easy to oxidize.
Laser scribing and controlled fracture
This kind of laser cutting uses a high-energy density laser beam to scan the surface of the material. It is a small groove that is heated outside the material and then applied with a certain amount of pressure, so the laser will cut along this small groove. The general material used in this cutting is brittle material.
The above four ways of laser cutting machine cutting are what we can often understand. Here we also want to remind you that although there are many cutting methods of laser cutting machine, we have to choose according to our own specific situation and cutting materials. Only by choosing cutting materials can we guarantee to reach the best standard.
