What is the difference between laser engraving machine and laser marking machine?

Laser marking machine can be divided into fiber laser marking machine, CO2 laser marking machine, UV laser marking machine and so on according to its working principle. Laser marking is the use of laser beam irradiation of surface materials,laserpecker 2 laser engraver so that the evaporation or lead to physical and chemical changes, so as to carve traces on the surface of the material or display the desired etching pattern, text.

Laser engraving machine is a technical equipment that utilizes laser for engraving. Unlike mechanical engraving machines and other traditional manual engraving methods, laser engraving machines use specific mechanical equipment for processing.laser pecker 4 So, what is the application of laser engraving machine in laser engraving processing? Let's take a look at the applications of laser engraving machines. In addition, we will also introduce the difference between laser marking machine and laser engraving machine.

First of all, laser engraving machines and laser marking machines have different processing depths. Laser engraving machines usually have deeper engraving depth and higher power. Their laser power ranges from 25W to 150W,laser pecker pro while the depth of engraved material can vary from 0.1mm to 80mm, depending on the material being processed. Generally speaking, materials such as wood products, sponges and acrylics are suitable for deeper engraving depths. In contrast, laser marking machines generally print to a depth of less than 5mm, and their laser rates range from 10W to 100W.

Second, the processing speeds of laser engraving machines and laser marking machines are also different. The cutting speed of the laser engraving machine is generally 200mm/s, while the engraving speed is 500mm/s; in contrast, the speed of the laser marking machine is generally three times that of the laser engraving machine. Therefore, in terms of speed, laser marking machines are faster than laser engraving machines. Taking mineral water producers as an example, their production line can produce about 100 meters of products per minute.

In addition, marking machines are far more accurate and faster than engraving machines. Lasers can use a fine beam of light to act on the surface of the material, and the line width can be as wide as 0.02 mm, which makes marking machines ideal for precision processing and anti-counterfeiting applications.

In addition, laser marking machines and laser engraving machines have different marking formats. Laser marking machines can generally mark formats up to 200*200mm, while laser engraving machines can handle larger formats. Since laser marking machines work by scanning with a galvanometer, their working width is relatively small. Laser engraving machines, on the other hand, replace the spindle with a laser focusing lens and process with a laser instead of a processing tool. As a result, it is possible to process larger formats as long as the xyz-axis is large enough, but precise control and handling of the machine's impact on efficiency is required. In addition, laser engravers have better heat dissipation due to the absence of optical path systems such as current detectors and focusing lenses, so their laser power output is not limited.

Finally, laser engraving machines and laser marking machines use different lasers. The optical path system of the laser engraving machine consists of three reflective lenses and a focusing mirror, and the commonly used laser is a carbon dioxide glass tube laser. The life of this glass tube laser is generally between 2000-10000 hours, belonging to the one-time use of the laser. While the laser marking machine laser is generally a metal tube laser (non-metal marking machine) and YAG solid-state laser (metal laser marking machine), its life is generally more than 5 years. It is worth mentioning that metal tube lasers can be re-inflated.

In summary, there are some differences between laser engraving machines and laser marking machines in terms of processing depth, processing speed, precision, speed, marking format and the laser used. According to the specific processing needs and material characteristics, selecting the appropriate processing equipment can improve productivity and processing quality.
