Most organic and inorganic materials can be cut with tubular lasers. In the metal processing industry, which accounts for a large part of the industrial manufacturing system, many metal materials, regardless of their hardness, can be cut without deformation. The main characteristics of material cutting by pipe laser cutting machine are as follows:
1. Small deformation of narrow slit workpiece
The laser beam of the pipe laser cutting machine is focused into a small point, so that the focus reaches high power density. At this time, the heat input by the beam far exceeds the part of the material reflected, conducted or diffused, and the material is rapidly heated to the degree of vaporization to form holes. With the relative linear motion of light beam and material, the hole continuously forms a very narrow slit. The thermal effect of trimming is very small, and there is basically no workpiece deformation.
In the cutting process of the pipe laser cutting machine, auxiliary steam suitable for the material to be cut is also added. In the process of steel cutting, oxygen, as an auxiliary steam, produces exothermic chemical reaction with molten metal to oxidize the material, which is also helpful to blow away the slag in the cutting joint. Of course, for materials with high reflectivity, such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible. The pipe laser cutting machine is burr free, wrinkle free and has high precision, which is superior to plasma cutting. For many mechanical and electrical manufacturing industries, because the modern pipeline laser cutting machine system controlled by microcomputer program can easily cut workpieces of different shapes and sizes, it usually takes priority over stamping and forming processes. Although its processing speed is slower than the stamping die, it does not consume the die, does not need to repair the die, and also saves the time of replacing the die, thus saving the processing cost and reducing the production cost, so it is more economical on the whole.
2. Non contact processing
The laser beam of the pipe laser cutting machine forms an action point with extremely strong energy after focusing, which has many characteristics when applied to cutting. First, laser energy is converted into amazing heat energy, which is stored in a very small area and can provide narrow straight edge slits. Secondly, the laser beam does not exert any force on the workpiece. It is a non-contact cutting tool, which means that the workpiece has no mechanical deformation. No tool wear, let alone tool conversion; Cutting materials do not need to consider their hardness. The performance of pipe laser cutting machine is not affected by the hardness of the material being cut, and it can cut any hard material. Third, the laser beam of the pipe laser cutting machine is controllable, with high adaptability and flexibility. It is very convenient to combine with automatic equipment, and it is easier to realize the automation of the cutting process.
3. Adaptability and flexibility
Compared with other conventional processing methods, pipe laser cutting machine has greater adaptability. Compared with other thermal cutting methods, as a thermal cutting process, other methods cannot act on a small area like laser beam, resulting in wide incision, large heat affected zone and obvious workpiece deformation. Laser can cut nonmetals, while other thermal cutting methods cannot.
