Brief description and working principle of 15W 532nm green laser cutting machine

As a new type of tool, laser cutting machine equipment is currently more and more maturely used in various industries. The working principle of the laser cutting machine is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting. This is also the most basic working principle of a laser cutting machine. Only by recognizing this concept can we have a guarantee for the subsequent work.

In fact, to be honest with his own characteristics, to put it simply, the laser cutting process uses an invisible beam instead of the traditional mechanical knife. It has high precision and fast cutting. It is not limited to the limitation of cutting patterns. Automatic layout saves materials and cuts. The characteristics of smoothness and low processing cost will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the work, and will not scratch the work surface during work; the laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, the plate deformation is small, and the slit is narrow; The incision has no mechanical stress, no shearing burrs; high processing accuracy, good repeatability, and no damage to the surface of the material; CNC programming, can process any plan, can cut large-scale whole boards, does not need to open a mold, and is economical and time-saving. As a new type of tool, laser equipment is increasingly used in various industries, including laser cutting machines, laser engraving machines, laser marking machines, laser welding machines, etc.

The quality of laser cutting can be measured by the following 6 standards

Generally speaking, the quality of laser cutting can be measured by the following 6 standards: 1. Cutting surface roughness. 2. Cut slag size. 3. The verticality and slope of the cutting edge. 4. The size of the round corner of the cutting edge. 5. Drag after stripes. 6. Flatness. The energy of the laser is concentrated into a high-density beam in the form of light. The beam is transmitted to the working surface to generate enough heat to melt the material. In addition, the high-pressure gas coaxial with the beam directly removes the molten metal, thereby achieving the purpose of cutting. It shows that there is a fundamental difference between laser cutting and machining of machine tools. It uses the laser beam emitted from the laser generator to focus into a high-power density laser beam irradiation condition through the optical path system. The laser heat is absorbed by the workpiece material, and the temperature of the workpiece rises sharply. After reaching the boiling point, the material begins to vaporize and form holes. , Accompanied by the high-pressure airflow, as the relative position of the beam and the workpiece moves, the material will eventually form a slit. The process parameters (cutting speed, laser power, gas pressure, etc.) and motion trajectory during slitting are controlled by the numerical control system, and the slag at the slit is blown away by a certain pressure of auxiliary gas.

The last point, I want to tell you that when using and buying a laser cutting machine, you must recognize its own advantages and disadvantages. Only by doing this well, we can find our own products from many varieties. , Because the laser cutting machine itself has many subdivided varieties, but their general working principle is the same, the general direction is the same, the rest is to look at the advantages and disadvantages of his various varieties and the construction direction.
