When it comes to the difference between laser engraving machines and CNC engraving machines, the most obvious difference is that laser engraving machines use laser melting for carving, while CNC engraving machines use digital technology to control cutting tools or laser, head and ultrasonic head carving. Laser engraving machines can be CNC engraving machines. CNC engraving machines can also be equipped with laser heads for carving, so that the two intersect. Next, let me tell you the specific differences between laser engraving machines and CNC engraving machines.

Although both use CNC systems, their working methods and mechanical structures are different. In contrast, the structure of CNC engraving machines is relatively simple. The engraving machine is controlled by a computer numerical control system to automatically select suitable engraving tools for engraving on the x, y, and z axes of the machine tool.

Laser engraving machines are divided into different specialized laser engraving machines based on their specific purposes. The structure of the dedicated machine is roughly the same. The laser source emits laser, and the CNC system controls the stepper motor of the laser plug to move the laser head, reflector, lens, etc. on the optical components. The focus moves on the X, Y, and Z axes of the machine tool to ablate the material.

The biggest difference between laser engraving machines and CNC engraving machines is that the cutting tools of laser engraving machines are a complete set of optical components, while the cutting tools of CNC engraving machines are carving tools for various entities.

Other differences:

1: Laser engraving and polishing are completed once, and CNC is completed twice.

2: The laser beam diameter is only 0.01mm, and the CNC tool is 20 times larger, which is a waste.

3: Laser speed is fast, 2.5 times faster than CNC engraving machines.

4: The energy consumption of lasers is lower than that of CNC engraving machines.

5: Laser is noise free, pollution-free, and efficient; CNC machine tools are noisy and pollute the environment.

6: Laser non-contact, no need to fix the workpiece, CNC is contact processing, and the workpiece is fixed.

7: Laser can process soft materials such as fabric, leather, thin film, etc; CNC cannot be processed because the workpiece cannot be fixed.

Therefore, the advantages of laser engraving machines are increasingly being applied in industries such as advertising signs, organic glass products, clothing processing, leather processing, and product labeling.
