HOW DOES LASER ENGRAVING WORK?

 

Small Laser Engraving Machine is typically used to engrave metal workpieces that will be exposed to various types of wear or surface treatments. Metal engraving works with steel and aluminum (including anodized and die-casting aluminum). 

From Solid to Gas: How It Works

Whereas laser etching melts the material surface to change its roughness, Laser Engraver sublimates the material surface to create deep crevices. This means that the surface instantly absorbs enough energy to change from solid to a gas without ever becoming a liquid.

To achieve sublimation, the Portable Laser Engraving Machine system must generate enough energy to allow the material’s surface to reach its vaporization temperature within milliseconds. Considering the extreme temperatures required for sublimation, laser engravers are pretty powerful tools.

Why lasers are used for cutting

Lasers are used for many purposes. One way they are used is for cutting metal plates. On mild steel, stainless steel, and aluminum plate, the Laser Cutting Machine is highly accurate, yields excellent cut quality, has a very small kerf width and small heat affect zone, and makes it possible to cut very intricate shapes and small holes. 

Focusing the laser beam can be done by a special lens, or by a curved mirror, and this takes place in the Wood Laser Cutting Machine head. The beam has to be precisely focused so that the shape of the focus spot and the density of the energy in that spot is perfectly round and consistent, and centered in the nozzle. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Think about using a magnifying glass to focus the sun’s rays onto a leaf, and how that can start a fire. Now think about focusing 6 KWatts of energy into a single spot, and you can imagine how hot that spot will get.
