How the Laser Cutting Process Works?

Laser is a focused beam of light, concentrating a lot of energy on a very small area. When this happens, material in front of a laser will burn, melt, or vaporize, making a hole.



Every material has its limitations and benefits when comes to a laser cutting. For instance, you may think that a laser can cut through anything, but that’s simply not the case.


Not every material is suitable for laser cutting.

That’s because every material requires a particular amount of energy to be cut.

For example, the energy needed to cut through paper is a lot less than the energy needed for a 20-mm thick steel plate.


Always check the laser’s power or at least what materials it can cut.


As a reference, a 40-W laser can cut through paper, cardboard, foam, and thin plastic, while a 300-W laser can cut through thin steel and thicker plastic. If you wish to cut through 2-mm or thicker steel sheets, you’ll need at least 500 W.
