Overview of laser engraving machine


What is laser engraving?

In the traditional concept of carving, what we understand is carving is the exquisite pattern chiseled out by the master hand-held carving knife or electric tool. Then the so-called laser engraving is the use of laser technology for engraving. The principle is to use laser thermal energy to burn or chemically change the engraved surface to produce engraving marks.

The advantage of laser engraving machine compared with hand-held tools is that the engraving characters and patterns can be controlled, the size can also be controlled, and the engraved patterns are relatively fine. The disadvantage is that it is not as three-dimensional as manual physical engraving, so the laser engraving machine is mainly used for shallow marking.

The structure of the laser engraving machine:

The laser engraving machine realizes the function of engraving, which mainly requires software control, mechanical transmission, and laser light source. The software is used as a human-computer interaction page for editing pictures and text, adjusting parameters, and starting and stopping.

The traditional engraving machine is driven by a stepping motor or a servo motor by the mechanical transmission part. Of course, due to the characteristics of the laser, many of the current machines have used the galvanometer system to realize the position control of the laser by controlling the tiny movement of the lens angle.

The laser light source is the core component of laser engraving, The characteristics of the light source determine the material effect of the laser machine to achieve engraving. The amount of energy has a significant impact on the depth and speed of engraving. The materials engraved by laser engraving machines are diversified: glass, crystal, acrylic, wood, marble, cloth, leather, felt, paper, PVC, plastic, mosaic and other non-metallic materials can be engraved or cut.
