Laser as a new tool is applied to a variety of industries, including laser cutting machine, laser engraving machine, laser marking machine, laser welding. Then how to use laser cutting? What are the advantages and disadvantages of laser-cutting?

 

First, laser power focuses a high-density beam in the form of optics, delivers to the worktable surface, producing enough heat to melt the materials, and the high pressure gas coaxial to the laser beam directly blows the melting metals away. This shows that laser cutting is different from the traditional mechanical cutting

 

Generally speaking, laser cutting quality can be measured by the following six criteria.

1. Cutting surface roughness Rz

2. Incision dross size

3. Trimming verticality and gradient u

4. Circular corner size R of Cutting edge

5. Delay amount n

6. Flatness F

 

Laser is a kind of light, similar to natural light, which is generated by atoms (molecules or ions, etc.) transitions. Laser is obviously different from ordinary light, because it is relied on self radiation for just a very short period, then entirely determined by stimulated emission radiation, therefore laser has a very pure color, almost no directional divergence and high luminous intensity. Laser also has high coherence, high intensity, high directivity, the laser generated by the laser after passing by the mirror and mirror exposure to the process by gathering items, so that the processing of goods (surface) by the strong heat and rapid temperature increase, to the point quickly due to high temperature melting or vaporization, with the laser running track to achieve the purpose of processing. Laser processing technology applications in the advertising industry is divided into: laser cutting, laser engraving.
