Where is the laser technology of laser marking machine applied? When did laser technology originate? Let's take a look at the editor below!

Laser technology is one of the four major scientific and technological inventions in the 20th century that are as famous as atomic energy, semiconductors and computers.

Laser has good monochromaticity, coherence, and directivity, and can accumulate high energy density in a small area, which is especially suitable for material processing.

At the end of the 1970s and the beginning of the 1980s, a brand-new laser application technology-laser marking technology quietly emerged in the world, and quickly became industrialized, becoming one of the largest application areas of laser processing.

The laser marking technology uses computer-controlled laser as a processing method. Its basic principle is: the computer controls a high-energy-density focused laser beam to follow a predetermined trajectory Acting on the surface of the workpiece that needs to be marked such as mechanical parts, electronic components, instrumentation, etc., so that the surface material can be vaporized or chemically changed to change the color, and the text, pattern, etc. with a certain depth or color are etched, so that the workpiece Permanent marks are left on the surface.

As a modern precision processing method, laser marking technology is compared with traditional processing methods such as corrosion, EDM, mechanical scribing, and printing. , Has unparalleled advantages:

1. The laser is used as a processing method, and there is no processing force between the workpiece and the workpiece. It has the advantages of no contact, no cutting force, and small thermal influence, which ensures the original accuracy of the workpiece.

At the same time, it has wide adaptability to materials, can make very fine marks on the surface of a variety of materials and has very good durability;

2. The space control and time control of the laser are very good, and the material, shape, size and processing environment of the processing object are very free. It is especially suitable for automatic processing and special surface processing.

And the processing method is flexible, which can not only meet the needs of laboratory-style single-item design, but also meet the requirements of industrialized mass production;

3. Laser marking is fine, and the lines can reach the order of millimeters to micrometers. It is very difficult to imitate and change the marks made by laser marking technology, which is extremely important for product anti-counterfeiting;

4. The combination of laser processing system and computer numerical control technology can form high-efficiency automatic processing equipment, which can print various characters, symbols and patterns. It is easy to use software to design marking patterns, change marking content, and adapt to the high-efficiency and fast-paced requirements of modern production; /p>

5. Laser processing has no pollution sources and is a clean, pollution-free and highly environmentally friendly processing technology;

Laser marking technology has been widely used in all walks of life, with high quality and high efficiency , Pollution-free and low-cost modern processing and production have opened up broad prospects.

With the continuous expansion of modern laser marking application fields, the requirements for miniaturization, high efficiency and integration of laser manufacturing equipment systems are also higher.
