Laser engraving machines: some common sense
We understand laser engraving as an imaginary master holding a carving knife or power tool, laserpecker metal engraving chiseling out beautiful patterns with his hand.
As a result, laser engraving refers to the use of laser heat in the process of developing chemical environment changes on the engraving surface to burn or create engraving marks.
Laser engraving machines and hand-held tools offer advantages such as the ability to control the engraving text and pattern, the ability to control the size, and the ability to design more complex engraving patterns. Laser engraving machines are mainly used for shallow scoring because there is no three-dimensional sense of manual physical engraving.
First, the laser engraving machine's structure. In order to achieve engraving, the laser engraving machine is essential.
To achieve several main components, software control, mechanical transmission, laser light source, where the software functions as a human-computer interaction page, used for editing pictures and text, adjusting parameters, and starting and stopping.
Through a stepper motor or a servo motor, the traditional engraving machine is driven by a mechanical transmission part. Due to the characteristics of lasers, many modern machines use galvanometers, which control the position of the laser by changing the angle of the lens.
Laser engraving relies on a laser light source as its core component, and its characteristics can influence the development of the laser function to achieve the material effect of Chinese engraving. The energy size has a significant impact on the engraving depth and speed.
Laser engraving machine light source classification
CO2 light sources, fiber light sources, violet light sources, green light sources, and diode light sources are currently used. Laser wavelengths and engraving efficiency are different.
Among them, CO2 laser engraving machine mainly studies the materials that can be engraved, such as wood, leather, plastic, and other non-metallic materials.
Optical fiber light sources can be used to engrave metal or painting materials with a high density. Generally, wood is difficult to carve, but it can be carved if it is not too dense.
The purple light source class is a high-end light source developed through comparative research, engraving is very fine and can be carved in a wide variety of ways
It is possible to carve transparent glass and other materials with a green light source. We have probably seen a lot of solid images in the middle of acrylic, often carved with a green light source.
It is similar to lighting a cigarette butt in the sun with a magnifying glass with a diode light source, originally used for stage lighting.
