Laser cutting is a focused beam of light, concentrating a lot of energy on a very small area. When this happens, the material in front of a laser will burn, melt, or vaporise, making a hole.
What Does Laser Cutting Mean?
Coined from the words Light Amplification by Stimulated Emission of Radiation. Being able to heat, melt and even vaporise material, lasers are seen as the ideal medium for channelling intense but controllable energy.
Though there are a number of ways that sheet metal can be shaped and cut, few are as precise, reliable and cost effective as laser cutting. The technology involved in laser cutting is so effective that a continuation and improvement of its future capabilities is inevitable
Can Every Material be Laser Cut?
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 laser.
