Everyone has become accustomed to the use of metal laser cutting machines in production activities. But for the metal laser cutting machine, many people don't know much about its cutting process. Let's give you a detailed introduction.   Generally speaking, the cutting process of metal laser cutting machine is mainly divided into three types:    First of all, flame cutting is a common method for rough processing of steel plates. It is also the oldest thermal cutting method. The thickness of the cut metal ranges from 1 mm to 100 mm. However, when the thickness of most low-carbon steel plates that you need to cut is below 20 mm, other cutting methods should be used. It uses the high temperature generated during the combustion of iron oxide to cut carbon steel. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect.  The cost of flame cutting equipment is low and it is the only economical and effective means to cut thick metal plates, but it has its shortcomings in thin plate cutting. Compared with plasma, the heat-affected zone of flame cutting is much larger, and the thermal deformation is relatively large. In order to cut accurately and effectively, the operator needs to have superb skills to avoid the thermal deformation of the metal plate in time during the cutting process.   followed by plasma cutting. A processing method that uses the heat of the high-temperature plasma arc to locally melt (and evaporate) the metal at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form the incision. Plasma cutting with different working gases can cut all kinds of metals that are difficult to cut with oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). The cutting effect is better; its main advantage is that the thickness of the metal is not large. At times, the plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, the speed can reach 5-6 times that of the oxygen cutting method.  Finally, it is wire EDM, or wire cutting for short. It is developed on the basis of EDM perforation and forming. It has not only developed the application of EDM, but also replaced EDM perforation and forming in some aspects. Today, wire-cut machine tools account for more than half of EDM machine tools. Its working principle The wire electrode 1 wound on the wire transport drum 4 moves at a certain speed along the rotation direction of the wire transport drum, and the workpiece 3 mounted on the machine tool table is moved relative to the electrode wire by the table according to a predetermined control trajectory. . One pole of the pulse power supply is connected to the workpiece, and the other pole is connected to the electrode wire. A certain discharge gap is always maintained between the workpiece and the electrode wire and the working fluid is sprayed. The spark discharge between the electrodes erodes a certain gap, and the continuous pulse discharge cuts the workpiece of the required shape and size.
