1. The laser cutting of the leather is narrow and the deformation of the workpiece is small.
The laser beam of the leather laser cutting machine is focused into a small spot of light, resulting in a high power density at the focus. At this time, the heat input by the beam far exceeds the portion that is reflected, conducted or diffused by the material, and the material is quickly heated to a degree of vaporization to evaporate to form a hole. As the beam moves relatively linearly with the material, the holes are continuously formed into slits of narrow width. The trimming is minimally affected by heat and there is essentially no deformation of the workpiece.
An auxiliary vapor body suitable for the material to be cut is also added during the cutting process. The steel is cut with oxygen as the auxiliary vapor and the molten metal to generate an exothermic chemical reaction to oxidize the material, while helping to blow away the slag in the slit. A type of plastic for cutting polypropylene uses compressed air, and flammable materials such as cotton and paper are cut to use an inert gas. The auxiliary vapor entering the nozzle also cools the focusing lens, preventing smoke from entering the lens holder and contaminating the lens and causing the lens to overheat.
Most organic and inorganic materials can be laser cut. In the metal processing industry where industrial manufacturing systems are heavily weighted, many metal materials, regardless of their hardness, can be cut without distortion. Of course, for high reflectivity materials such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible.
Leather laser cutting has no burrs, wrinkles, high precision, and is superior to plasma cutting. For many electromechanical manufacturing industries, modern laser cutting systems controlled by microcomputer programs can easily cut workpieces of different shapes and sizes, which are often preferred over die cutting and molding processes; although they are slower than die punching, However, it has no mold consumption, no need to repair the mold, and saves time for mold replacement, thereby saving processing costs and reducing production costs, so it is more cost-effective to consider.
2, leather laser cutting is a high-energy, density controllable non-contact processing.
The laser beam is focused to form a very small point of action with very strong energy, and its application to cutting has many features. First, the laser light energy is converted into amazing heat energy that is kept in a very small area and is available
(1) narrow straight edge slitting;
(2) the smallest heat affected zone adjacent to the trim;
(3) Minimal local deformation.
Secondly, the laser beam does not exert any force on the workpiece, it is a contactless cutting tool, which means
(1) The workpiece has no mechanical deformation;
(2) There is no tool wear, and there is no problem with the conversion of the tool;
(3) The cutting material does not need to consider its hardness, that is, the laser cutting ability is not affected by the hardness of the material to be cut, and any hardness material can be cut.
Again, the laser beam is highly controllable and has high adaptability and flexibility, thus
(1) It is convenient to combine with automation equipment, and it is easy to automate the cutting process;
(2) Since there is no restriction on cutting the workpiece, the laser beam has an infinite profiling capability;
(3) Combined with the computer, the whole board can be discharged and the material can be saved.
3, leather laser cutting has a wide range of adaptability and flexibility.
Laser cutting has greater flexibility than other conventional processing methods. First, as with other thermal cutting methods, as a thermal cutting process, other methods cannot act as a laser beam on a very small area, resulting in a wide slit, a large heat affected zone, and significant workpiece deformation. Laser can cut non-metal, while other hot cutting
