Some common sense about laser engraving machine
2022-12-02 09:33:49 technical college

First of all, what is laser carving and what is its concept? From the perspective of traditional carving concepts, what we know about sculpture is that a teacher Fu chisels beautiful patterns with a carving knife or electric tools.

So the so-called laser carving is to use laser technology to carve. The principle of the carving machine is to use laser heating or chemical changes on the carving surface to produce carving marks.

Compared with hand tools, the laser engraving machine has the advantages of carving characters, pattern control, size control, and more fine carving patterns. The disadvantage is that it is not as three-dimensional as manual physical carving. Therefore, the laser engraving machine is mainly used for shallow marking.

The concept is clear. Let's talk about the structure, functions and main requirements of the laser engraving machine.

The key is that the software controls the mechanical transmission of several parts of the laser luminous source. As a human-computer interaction page, the software is used to edit image text, adjust parameters, start, etc.

Of course, due to the characteristics of the laser, most modern machines use mechanical transmission, which controls the position of the laser by controlling the micro motion of the angle of the micro lens. The traditional engraving machine is driven by a stepping motor or a servo motor.

The luminous source of the laser is the core part of laser engraving. The characteristics of the light source determine the role of the laser function on the engraving materials. The size of the energy has a significant impact on the depth and speed of the engraving.

Classification of laser engraving machine light sources

The common light sources of laser engraving machines on the market today are mainly CO2 light source, optical fiber light source, purple light source, green light source and diode light source. Its laser wavelength is different, carving efficiency is also very different.

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

• For optical fiber light source, the main carving materials are metal or materials with high paint density. Wood is generally not easy to carve, unless the density is very high.

·Purple light source is a kind of high-grade light source, with very fine carving and a wide range of carving.

• Green light source. We may have seen many stereo images in the middle of acrylic, which are usually carved with green light source. Glass and other transparent materials can be carved.

The diode light source, which should be used as the light source for stage lighting, has achieved a magnificent turn in the laser engraving industry, and its engraving principle is a bit like a magnifying glass lighting cigarette butt under the sun.

The laser engraving machine standard is selected.

I think many friends who want to buy laser engraving machines are more concerned about this problem. Everyone must choose a practical and economical laser model. Therefore, the advantages and disadvantages of various laser equipment can be understood before selection.

CO2 laser engraving machine: it has the advantages of wide range of engraving materials, wood veneer, glue, etc., fast engraving speed and high precision. Disadvantages: The machine is bulky and difficult to handle at 40-50kg, and the price is generally moderate, which is suitable for factory use.

The optical fiber laser engraving machine has the advantages of high engraving precision and fast speed. It is suitable for batch operation in the factory and can be connected to the automatic production line of the factory. Defective machines are generally more expensive, larger in size and more than 30 kg in weight.

The utility model relates to a purple laser engraving machine, which has the advantages that the engraving materials are wide, and the engraving materials can be metal or nonmetal. One machine can be used for multiple purposes. Due to the characteristics of purple light source, the price is expensive and the machine burden is heavy. Apply high-end manufacturing industry.

Green laser engraving machine, which can realize three-dimensional engraving and 3D positioning engraving. The disadvantage of large size is also expensive.

The advantages of the diode laser engraving machine are that the price is as low as 1000 yuan or less, and the small size can move. The disadvantage is that the carving speed is slow and it cannot be carved with pure metal. Because of the speed limit, it is generally suitable for personal DIY household use, or small and medium-sized businesses to customize in small quantities.
