With the development of laser technology, the types and performance of laser equipment are also being improved and enhanced. The common laser marking equipment on the market today are laser engraving machines and laser marking machines. Many friends say that these two machines feel similar. So, what is the difference between laser marking machine and laser engraving machine?

1. Working principle is different

Laser marking machines use laser beams to make permanent marks on the surface of various materials.handheld laser marking machine The role of marking is through the surface layer of material evaporation so that the deep material exposed, or through the light energy caused by the surface layer of material chemical and physical changes in the "carving" traces, or through the light energy to burn off part of the material to show the required etching patterns, text.

Laser engraving machine is a kind of laser equipment that utilizes the thermal energy of laser to engrave and cut the material. Also known as laser cutting machine, laser etching machine and so on.

2. Different lasers used

Laser marking machine is mainly divided into CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine. The service life of various lasers is different, such as metal tube lasers and YAG solid-state lasers, the service life is generally about 30,000 hours. Of course, the fiber laser marking machine laser has the longest service life, up to 100,000 hours.

Laser engraving machine can be divided into CO2 non-metallic laser engraving machine and fiber metal engraving machine.CO2 non-metallic laser engraving machine laser is generally CO2 glass tube, glass tube laser life is generally 2000-10000 hours. Fiber laser can be used continuously for more than 10w hours.

3. the applicable materials are different, the application of different industries

CO2 laser marking machine for a variety of non-metallic materials, a wide range of applications. All kinds of materials can be marked with permanent high-quality marking. Applied to clothing accessories, pharmaceutical packaging, alcohol packaging,little pecker laser engraver construction ceramics, beverage packaging, fabric cutting, rubber products, shell nameplate, craft gifts, electronic components, leather and other industries. However, fiber laser marking machine can be widely used for metal products.

Laser engraving machine can be roughly divided into: non-metal laser engraving machine and metal laser engraving machine. Therefore, it can be used for both metal and non-metal materials with a wide range of applications. For example, it can be used for laser processing of non-metallic materials such as bamboo, wood, crystal, cow horn, cardboard, plexiglass, marble, fabric, leather, rubber, plastic and so on. Clothing, embroidery, fabric toys, home fabrics, handbags, gloves, leather in the toy industry, leather cutting and surface engraving. Crafts, models, advertising, decoration, electrical appliances, plastics and other industries, such as acrylic panels, medium density decorative panels and other non-metallic sheet precision cutting.

4. different processing depth

Laser marking machine only marking on the surface of the material, the depth is very shallow, the general depth is less than 0.5mm, while the depth of the laser engraving machine can mark very deep, ranging from 0.1mm to 100mm, and can go deep inside the object. Even if it is punched through, the specific depth still depends on the material.

5. Different processing speeds

Laser engraving machine engraving speed is generally the fastest cutting speed 200mm / s, engraving speed 500mm / s; laser marking machine speed is generally three times the speed of the laser engraving machine.

6. different processing technology:

Laser engraving machine can be equipped with optional electric lifting platform and rotary axis, can be engraved cylindrical, shaped, sphere and other regular or irregular objects. Due to the stability control of the Q head and laser marking machine optical path settings, the platform can be adjusted left and right up and down to adjust the focus, so it is mostly applicable to plane engraving.

7. Different prices

Different configurations, such as different lasers and different power, will have different final prices. Generally speaking, laser engraving machine engraving depth is deeper, higher power. But the general laser marking machine has a shallow print depth and lower laser power. For non-metal laser engraving and cutting machine, the price of small power is much cheaper than laser marking machine, but the high power laser engraving machine is also more expensive.
