Now with the rapid development and innovation of laser technology, there are a wide range of laser applications in many industries, such as aerospace, industrial processing, etc. In every field, lasers play a pivotal role in laser applications. And the laser equipment is not a small number, laser marking machine, laser laser engraving machine is one of the laser equipment, then what kind of work process and application is it in the industrial field?
First of all, understand how the laser marking machine works: the main purpose of applying the laser marking machine is to mark, and marking is the marking on the surface of various objects that people often see in processing. The actual working effect is to expose the internal matter by evaporation of the surface layer of the object, to make a trace of chemical changes on the surface of the material by light, or to burn some of the surface material by light, so that some patterns or characters The content appears on the surface of matter. The laser marking machine utilizes the characteristics of high density and energy of the laser to concentrate a certain part of the surface of the material, so that the surface of the substance vaporizes or a chemical reaction of the color occurs, so that the mark left on the surface of the substance. Because of the characteristics and advantages of the laser marking machine, it is widely used in very fine and high-precision grades, such as electronic and electrical circuits, precision instrument processing, jewelry processing, hardware processing and other occasions.
The second is to understand the superiority of the laser marking machine: although the price of the laser marking machine is relatively expensive, in the field of finishing, it plays a role that the pneumatic marking machine and the heritage inkjet printer cannot match, because there are some advantages. Sex and characteristics are only available in laser marking machines, as follows:
1. Product anti-counterfeiting: Now with the advancement of technology, many authentic brands will always be occupied by some counterfeit products at low selling prices, which makes some formal enterprises suffer great economic losses, but laser marking is applied. The products that are shipped from regular enterprises are marked with various small characters, patterns and symbols. There is no way for counterfeit processing factories to do this step, which can effectively prevent counterfeit and shoddy products from disrupting the product market.
2. The laser marking machine beam is extremely small, so that the materials on the surface of different materials can be removed or reacted point by point. This superiority is characterized in that unnecessary parts can be removed without directly contacting the surface of the material, which is typical. Non-contact processing, at the same time does not produce mechanical pressure or some mechanical extrusion, protect the processed items from damage, improve the pass rate of the product processing.
3, can complete some non-standard processing technology, laser marking machine after focusing, the light spot is small, the same size is also small, work is also completed, the time spent on the surface of the object is very short, so it will not produce a lot of processing heat, Even if there is heat, the area that causes the regional influence is very small, and the processing can be said to be very fine, which is advantageous for processing some special fine special processes without causing deformation of the object to be processed.
4. The laser marking machine uses a laser beam to mark the surface of various materials. The effect of marking is to expose deep substances by evaporation of surface substances, or to "engraving" traces by chemical or physical changes of surface substances caused by light energy, or to burn off some substances by light energy to show the desired etching. Patterns, texts, barcodes, and other types of graphics, marking is not easy to wear, marking will not become a three-nothing product after a long time of use, which is not comparable to traditional marking machines.
