Most organic and inorganic materials can be cut with tubular lasers. In the metal processing industry, which occupies a large part of the industrial manufacturing system, many metal materials, regardless of their hardness, can be cut without deformation. The main features of metal pipe laser cutting machine cutting materials are as follows:
1. Small deformation of narrow-slit workpieces
The laser beam of the metal pipe laser cutting machine is focused into a small spot, so that the focus can reach a high power density. At this time, the heat input by the beam far exceeds the reflection, conduction, or diffusion of the material, and the material is quickly heated to the degree of vaporization, forming a hole. With the relative linear movement of the light beam and the material, the holes continuously form very narrow slits. The thermal effect of the trimming is very small, and there is basically no deformation of the workpiece.
In the cutting process of the metal pipe laser cutting machine, auxiliary steam suitable for the material to be cut is also added. In the steel cutting process, oxygen acts as an auxiliary steam to produce an exothermic chemical reaction with the molten metal to oxidize the material, and at the same time help blow away the slag in the cutting seam. 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 has no burrs, no wrinkles and high precision, which is better than plasma cutting. For many electromechanical manufacturing industries, because modern pipe laser cutting machine systems controlled by microcomputer programs can easily cut workpieces of different shapes and sizes, they usually take precedence over stamping and forming processes. Although its processing speed is slower than that of punching dies, it does not consume molds, does not need to repair molds, and also saves time for mold replacement, thereby saving processing costs and reducing production costs, so it is more economical on the whole.
2. Non-contact processing
The laser beam of the metal pipe laser cutting machine is focused to form an extremely powerful point of action, which has many characteristics when applied to cutting. First, the laser energy is converted into amazing thermal 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 there is no mechanical deformation of the workpiece. There is no tool wear, let alone tool conversion; the cutting material does not need to consider its hardness, the performance of the metal 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, has high adaptability and flexibility, and is very convenient to combine with automation equipment, making it easier to automate the cutting process.
3. Adaptability and flexibility
Compared with other conventional processing methods, the tube laser cutting machine has greater adaptability. Compared with other thermal cutting methods, it is also used as a thermal cutting process. Other methods cannot act on a small area like a laser beam, resulting in a wide incision, a large heat-affected zone and obvious deformation of the workpiece. Lasers can cut non-metals, while other thermal cutting methods cannot.
