For many operations to form text, patterns and so on on the surface of an object, the work of a laser engraving machine is required, but the engraving machine itself is divided into many types, which troubles the manufacturers of laser smoke filters for these laser engravers.

What is the principle of laser engraving? The so-called laser engraving is the use of laser technology for engraving. The principle is to use laser heat to burn or chemically change the engraved surface to produce engraving marks.

The classification of the light source of the laser engraving machine:

Among them, CO2 laser engraving machine is mainly suitable for engraving materials such as wood, leather, plastic and other non-metallic materials.

Optical fiber light source, the main materials for engraving are metal or lacquered materials with higher density. Wood is generally not easy to engrave, unless it is very dense and hard, it can be engraved.

The purple light source is a relatively high-end light source. The engraving is very fine and the engraving range is wide. Precision machining parts are very much needed.

Green light source, we may have seen a lot of three-dimensional images in the middle of acrylic, usually engraved with green light source. It can engrave transparent glass and other materials, which is more used in the advertising industry.

The diode light source, which was originally a stage lighting light source, has achieved a magnificent turn in the laser engraving industry. The engraving principle is somewhat similar to a magnifying glass placed under the sun to light a cigarette.

Knowing the types of laser engraving light sources and processing materials, PURE-AIR laser fume extractor can better develop the supporting equipment.
