The difference between laser marking machine and laser engraving machine

Many people mix the laser marking machine and the laser engraving machine, thinking that they are the same kinds of machines. Well, technically speaking, there are subtle differences between these two machines. Today, we are going to go deeper into the differences of these two.

1.Working principle

Laser marking machine uses laser beam to vaporize the surface material. The surface material will have chemical change or physical change and then the inside material will be exposed. This process will create the marking. 

Laser engraving machine, however, uses laser beam to engrave or cut. It actually engraves deep into the material. 

2. Applied materials

Laser engraving machine is a kind of deep engraving and often works on non-metal materials. Laser marking machine, however, just has to work on the surface of the materials, so it is applicable to non-metal and metal materials. 

3. Speed and depth

As mentioned before, laser engraving machine can go deeper into the materials than laser marking machine. In terms of speed, laser marking machine is much faster than laser engraving machine. It can generally reach 5000 mm/s -7000mm/s.

4. Laser source 

Laser engraving machine is often powered by CO2 glass laser tube. However, laser marking machine can adopt fiber laser, CO2 laser and UV laser as the laser source. 

Either laser engraving machine or laser marking machine, they both have a laser source inside to produce high quality laser beam. For high power laser engraving machine and laser marking machine, they required more powerful laser chiller unit to take away the heat. S&A Teyu has been focusing on laser cooling solution for 19 years and develops different series of laser chiller units specifically designed for cooling CO2 laser engraving machine, CO2 laser marking machine, UV laser marking machine and so on.
