What are the Differences Between A Laser Marking Machine and A Laser Engraving Machine?

Both laser marking machines and laser engraving machines are commonly used machines in the processing of precision parts. In many cases, operators are confused about the two types of equipment. But from a professional point of view, they are very different in the application of materials, depth, working speed, and laser. Next, DXTECH will introduce you to the difference between these two machines.


The laser engraving machine can add an electric lifting platform and rotating shaft. Therefore, it can engrave complex-shaped objects such as cylinders and special-shaped objects. However, due to the Q head and optical path settings, the laser marking machine platform can only adjust the focal length left and right. Therefore, laser marking machines are most suitable for flat engraving.

Laser engraving machines generally engrave or cut non-metallic materials. However, laser marking machines are generally not used for deep engraving, and they can mark on most metal and non-metal materials.


The laser marking machine only marks the surface of the material. The depth is extremely shallow, generally less than 0.5mm. But the depth of the laser engraving machine can be deep. The depth varies from 0.1mm to 100mm. Usually, The exact depth depends on the material.


The engraving speed of the laser engraving machine is generally as fast as the cutting speed can reach 200mm/s. At the same time, laser marking machines are generally three times faster than laser engraving machines. Therefore, the speed of the laser marking machine is significantly faster than that of the laser engraving machine.


The optical path system of the laser engraving machine is composed of three reflective lenses and a focusing lens. Its laser is generally a carbon dioxide glass tube. The service life of glass tube lasers is between 2000-10000 hours. The lasers of laser marking machines are generally metal tube lasers (non-metal marking machines) and YAG solid-state lasers (metal laser marking machines). The life of these two lasers is generally more than five years. In addition, workers can re-inflate the metal tube of the laser marking machine for recycling.


All in all, laser marking machines and laser engraving machines are two completely different processing equipment. Their application are different. The only thing in common is that they all use lasers as the driving force for production. In production, the operator should choose a specific machine according to the specific processing requirements. DXTECH has many years of experience in the production of laser cutting machines and laser marking machines. We are willing to provide professional advice to customers who are still struggling to choose laser equipment. If you want to know more about laser equipment, please continue to pay attention to us.
