Some Common Sense About Laser Engraving Machine

Mar 16, 2022

Let's talk about the concept of laser engraving first. What is laser engraving? Traditionally, the carving is considered as those exquisite patterns chiseled out by masters with a carving knife or a power tool. The so-called laser engraving is to engrave with laser technology. The principle of laser engraving is to use laser heat to burn or chemically change the engraved surface to produce imprints.

1. About the laser engraving machine

Compared with hand-held tools, the advantage of the laser and engraving machine is that you can control the engraving characters, patterns and size, and the engraved patterns are relatively delicate. However, its disadvantage is that it is not as three-dimensional as manual physical carving. Therefore, the laser and engraving machine is mainly used for shallow marking. The realization of the engraving function of the laser engraving machine mainly requires software control, mechanical transmission, and several major components of the laser light source, among which the software, as a human-computer interaction page, is used for editing pictures and text, adjusting parameters and start-stop.

The mechanical transmission part of the traditional engraving machine is driven by a stepper motor or a servo motor. Of course, due to the features of lasers, many modern laser engraving machines have applied the galvanometer system to control the position of the laser by moving the lens angle slightly. The laser light source is the core component of laser engraving, the characteristics of the light source determine the material effect that laser engraving machine can achieve. The amount of energy has a significant impact on the depth and speed of engraving. Specialized knowledge about pro laser cutting may help you.

2. Classification of the light source of the laser engraving machine

At present, the common light sources of laser engraving machines in the market mainly include CO2 light source, fiber light source, purple light source, green light source, and diode light source. The different laser wavelengths differentiate the engraving performance greatly. CO2 laser engraving machine is mainly suitable for engraving materials such as wood, leather, plastic and other non-metallic materials. Fiber light source laser engraving machines are mainly used to engrave metal or lacquered materials with relatively high density. Wood is difficult to carve, unless it is very dense and hard. The purple light source is a relatively high-end light source that is able to engrave finely and has a wide range of applications. Many three-dimensional images in the middle of acrylic are basically engraved with a green light source, which is usually used to engrave materials like transparent glass. The diode light source was originally the light source of stage lighting, and it has been transformed magnificently in the laser engraving industry. The engraving principle of the diode light source is similar to using a magnifying glass to focus the sun's rays to light a cigarette.
