Laser engrave machine is a new kind of laser machine , function to improve the efficiency of the carving, so that the surface of the carved smooth, rounded, quickly reduced the temperature of the carved non-metallic materials to reduce the deformation of the carved and internal stress.
A laser engraving machine can be thought of as three main parts: a laser, a controller, and a surface. The laser is like a pencil – the beam emitted from it allows the controller to trace patterns onto the surface. The controller direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.
There are three main genres of engraving machines: The most common is the X-Y table where, usually, the workpiece (surface) is stationary and the laser optics move around in X and Y directions, directing the laser beam to draw vectors. Sometimes the laser is stationary and the workpiece moves. Sometimes the workpiece moves in the Y axis and the laser in the X axis. A second genre is for cylindrical workpieces (or flat workpieces mounted around a cylinder) where the laser effectively traverses a fine helix and on/off laser pulsing produces the desired image on a raster basis. In the third method, both the laser and workpiece are stationary and galvo mirrors move the laser beam over the workpiece surface. Laser engravers using this technology can work in either raster or vector mode
Laser engraving is a process where the laser beam physically removes the surface of the material to expose a cavity that reveals an image at eye level.
The laser creates high heat during the engraving process, which essentially causes the material to vaporize.It’s a quick process, as the material is vaporized with each pulse.This creates a cavity in the surface that is noticeable to the eye and touch.
To form deeper marks with the laser engraver, repeat with several passes.
Although engraving is a subsection of laser marking, it still differs in many ways:
There are three types of laser engraving: etching, deep laser engraving and laser ablation (the difference between the three is what the surface is and how much you remove).This is the most common option for people who want something personalized or customized.
What can we do with laser engrave machine ?
It is more legible than traditional engraving for small objects such as jewelry,Wood, paper, leather, cloth, organic glass, resin, acrylic, wollens, plastic,rubber ceramic tile, crystal, bowlder, bamboo,etc.It provides you with more font options.There is a smaller chance of product damage or deformation.Laser engraving machines are faster than traditional methods.
