What is the difference between fiber laser marking machine and CNC engraving machine, who has more advantages?

The main difference between a laser engraving machine and a CNC engraving machine is that the tools are different. The laser engraving machine uses laser as a tool for engraving, and the CNC engraving machine uses digital technology to control and use alloy tools to engrave. So what are the specific differences between the two?

Both devices use digital control systems, but their working methods and mechanical structures are different. The CNC engraving machine is controlled by the computer numerical control system, and the engraving machine automatically selects the appropriate engraving tool for engraving. According to the specific use, the laser engraving machine is divided into different special machine tools. The structure of the special machine is roughly the same. The laser source emits laser light, and the CNC system controls The stepper motor of the laser plug makes the laser head, mirror, lens, etc. move on the optical components, so that the focus moves on the X, Y, and Z axes of the machine tool, resulting in material corrosion.

The difference between laser engraving machine and CNC engraving machine The tools of the laser engraving machine are a complete set of optical components, and the tools of the CNC engraving machine are various solid engraving knives. Other differences are as follows:

1. Laser engraving does not require tool consumables, and CNC tool consumables require a large investment.

2. The laser speed is 2.5 times faster than the CNC engraving machine.

3. The energy consumption of CNC engraving machine is higher than that of laser engraving

4. Laser engraving has no noise, no pollution and high efficiency ; CNC machine tools have high noise and pollute the environment.

5. The laser is non-contact and does not need to fix the workpiece. The CNC is contact processing and the workpiece is fixed.

6. The laser can process soft materials, such as cloth, leather, etc. CNC cannot be processed because the workpiece cannot be fixed.

Therefore, the advantages of laser engraving machines have been more and more widely used in advertising signs, plexiglass products, garment processing, leather processing, product identification and other industries. The CNC engraving is more suitable for the engraving of large metal parts.
