CO2 Laser Engraver Machines

Principle and application of laser engraving machine

Laser engraving processing principle and technology introduction:

Laser engraving is similar to laser marking and laser cutting. It also uses a focused laser beam with high power density to act on the surface or interior of the material to vaporize or physically change the material.

Laser engraving principle:

The working principle of the laser engraving machine 1. The laser engraving machine generates a laser beam through the laser, and then transmits it by the reflector and irradiates it to the processed item through the condensing mirror. Then the laser makes the processed item receive strong thermal energy and the temperature increases sharply, which makes the point due to high temperature. The rapid melting or vaporization is controlled by computer software and cooperates with the running track of the laser head to realize laser processing.

The laser engraving machine is connected to the computer through the data transmission line, and the matching special marking control software is installed in the computer. The marking software is used to realize the input of text and pictures, and the laser is controlled by the software on the item. Run marking.


By controlling the relevant parameters such as laser power, spot size, spot movement trajectory and movement speed, the processing material can form the required three-dimensional graphic pattern.


The physical denaturation of instantaneous melting and gasification of processing materials under laser irradiation achieves the purpose of processing. Laser processing features: There is no contact with the surface of the material, it is not affected by mechanical movement, the surface will not be deformed, and generally does not need to be fixed. Not affected by the elasticity and flexibility of the material, it is convenient for soft materials. High machining accuracy, fast speed and wide application fields.

Laser engraving machine application areas and machinable materials

  1. Acrylic plate (plexiglass)

Acrylic is especially widely used in the advertising industry. Available in a variety of shapes and sizes, using a laser engraver is relatively inexpensive. In general, plexiglass is engraved on the back, that is to say, it is engraved from the front and viewed from the back, which makes the finished product more three-dimensional. When engraving on the back, please mirror the graphics first, and the engraving speed should be fast and the power should be low. Plexiglass is relatively easy to cut, and a blowing device should be used when cutting to improve the quality of the cut.

  1. MDF

MDF is the kind of wooden pallet we often use for sign linings. The material is high density board with thin wood grain on the surface. The laser engraving machine can engrave on this cutting-edge material factory, but the color of the engraved pattern is uneven and black, and it is generally colored. Usually you can use a 0.5mm two-color plate for inlays to get better results by learning the proper design. After engraving, use a damp cloth to clean the MDF surface.


  1. Wood

Wood is easy to engrave and cut with a laser engraver. Light-colored woods like birch, cherry, or maple are well-gassed by the laser, making them more suitable for engraving. Each wood has its own characteristics, and some are denser, such as hardwoods, which require higher laser power when engraving or cutting.

The depth of the laser engraving machine cutting wood is generally not deep, within 5mm, this is because the power of the laser is small, if the cutting speed is slowed down, the wood will burn.

Advertising decoration: engraving (cutting) of plexiglass products, laser production of medals and plaques, laser engraving (cutting) of two-color plates, engraving (cutting) of other non-metallic plates

Printing and packaging: rubber plate laser engraving, printing roller laser engraving, paper product laser cutting

Leather garments: leather and surface pattern engraving, garment fabric pattern cutting

Craft gifts: bamboo slip laser engraving, woodblock book laser engraving, mahogany laser engraving, two-color plate laser engraving, box-shaped handicraft engraving, ceramic laser engraving


Laser engraving features:

  1. Wide range of engraving. It can engrave metal materials as well as non-metallic materials, and even can engrave high refractory and hard and brittle materials (such as ceramics, quartz, glass, heat-resistant alloys, etc.), and can also go deep into the material. Sculpture.

2, the speed is fast. Laser engraving is more than 100 times faster than the general engraving method, and can ensure the accuracy of repeated engraving.

  1. High quality. The product has high resolution, can achieve fine engraving, and is clean and pollution-free, and the area affected by the oxidation, deformation and thermal expansion of the engraved material is relatively small.
  2. Low energy consumption. The engraving process is simple, there are few ability conversion links, and it is a surprise engraving, with less loss of raw materials and improved work efficiency.
  3. High degree of automation. The combination of laser engraving and automatic control technology makes it easy to realize the automatic control process.
