The Difference Between Laser Engraving Machine And Laser Marking Machine

Laser marking machine is often called laser marking machine, laser marking machine, laser marking machine, according to its working mode can be divided into fiber laser marking machine, CO2 laser marking machine, ultraviolet laser marking machine and so on. The principle of laser marking is to use laser beams to expose the evaporation of surface materials to reveal deep substances, or to cause physical changes in the chemical changes of surface materials to engrave traces, or to burn some of the materials through light energy to show the desired etching pattern. , text.

Laser marking machine and laser engraving machine

The laser engraving machine, also called the laser engraving machine, is a technological device that uses laser to engrave materials that need to be engraved. Laser engraving machine is different from mechanical engraving machine and other traditional hand engraving methods. What kind of difference is the mechanical equipment used in laser engraving processing? Let’s take a look at the laser engraving machine in laser engraving processing. Laser marking machine to distinguish knowledge!

A: The depth of processing and printing is different. The laser engraving machine generally has a deeper depth of engraving and a larger power. Laser power ranges from 25W to 150W. The depth of the engraving material varies from 0.1 mm to 80 mm, and the depth of engraving depends on the specific material. Generally, wood products, sponges, acrylics and other materials have deeper engraving depth. Laser marking machines generally have a print depth of less than 5 mm and a laser rate of between 10 W and 100 W.

Second: the processing speed is different, the engraving speed of laser engraving machine is generally 200mm/s cutting speed and 500mm/s engraving speed; the speed of laser marking machine is generally three times that of laser engraving machine. At speed, the laser marking machine is faster than the laser engraving machine. Like the mineral water manufacturer, the flow line of 1 minute is about 100 meters.

Three: The accuracy and speed of the marking machine is much higher than that of the engraving machine. The laser can act on the surface of the material with a thin beam, and the thin line width can reach 0.02mm. It opens up a wide application space for precision machining and increased anti-counterfeiting.

Four: the difference between the marking format: Raman laser marking machine can generally mark the format of 200 * 200mm, the engraving machine can engrave large format. The laser marking machine uses a galvanometer scan, so the working width is relatively small. The laser engraving machine says that the spindle on an engraving machine is replaced by a laser focusing lens, and the laser is used instead of the tool for machining. Therefore, as long as the xyz axis is large enough, it is possible to process a large format with a large format, but precision and processing. Efficiency is greatly affected by machinery. In addition, since there is no galvanometer, the optical path system such as the focus lens is better for cooling, so the laser power output is not limited.

V: Different lasers: The optical path system of the laser engraving machine is composed of three reflective lenses and a focusing mirror. The laser is generally a carbon dioxide glass tube. The life of a glass tube laser is generally within 2000-10000 hours. Carbon dioxide glass tube lasers are disposable. The lasers of laser marking machines are generally metal tube lasers (non-metal marking machines) and YAG solid-state lasers (metal laser marking machines), and their lifetimes are generally more than five years. The metal tube of the laser marking machine can be inflated again.

Six: Differentiation of engraving and marking materials, laser engraving machine engraving materials diversified: glass, crystal, acrylic, wood, marble, cloth, leather, felt, paper, PVC, plastic, mosaic, etc. Non-metallic materials can be engraved Or cutting. The industry of laser marking machines is mainly for cloth leather, wood products, ceramics or metal products.
