I. Understand the laser engraving machine


In the traditional concept of engraving, we understand engraving as imaginary workers hand-held carving knives or power tools to chisel exquisite patterns. Then the so-called laser engraving is the use of laser technology to engrave. The principle is to use the burning of laser heat or chemical changes on the engraved surface to produce engraving marks. Compared with hand-held tools, the advantage of laser engraving machine is that the engraved text and pattern can be controlled, the size can also be controlled, and the engraved pattern is also relatively fine. The disadvantage is that it is not as three-dimensional as manual physical engraving. Therefore, the laser engraving machine is mainly used for shallow marking.


The concept is clear, let's talk about the structure of the laser engraving machine. 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. It is used to edit picture text, adjust parameters and start and stop. Laserpecker has desktop laser engraving machine for sale, if you are interested in it, shop now!


The traditional engraving machine like small laser printing 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 modern machines have used a galvanometer system to control the position of the laser by controlling the tiny movement of the angle of the lens. The laser light source is the core component of laser engraving, the characteristics of the light source determine the material effect of laser engraving, and the amount of energy has a significant impact on the depth and speed of engraving .



II. The classification of the light source of the laser engraving machine


At present, the common light sources of laser engraving machines on the market mainly include CO2 light source, fiber light source, purple light source, green light source, and diode light source. The laser wavelength is different, and the engraving efficiency is also very different . The CO2 laser engraving machine is mainly suitable for engraving non-metallic materials such as wood, leather, plastic, etc.; for optical fiber light sources, the main engraving materials are metal or lacquer. Density comparison big material. Generally speaking, wood is not easy to carve, unless it is extremely dense and hard to carve; the purple light source is a relatively high-end light source, the carving is very fine and the carving range is wide ; the green light source, we may have seen many the three-dimensional image in the middle of the acrylic is generally engraved with a green light source. Transparent glass and other materials can be engraved ; diode light source, which was originally a light source for stage lighting, has achieved a gorgeous turn in the laser engraving industry .
