Let's talk about the concept of laser engraving first, so what is laser engraving?
In the traditional concept of carving, we understand that carving is to imagine that the old master holds a carving knife or an electric tool to chisel out exquisite patterns. So the so-called laser engraving is the use of laser technology for engraving. Its principle is to use laser heat energy to burn or make chemical changes on the engraving surface to produce engraving marks. Compared with hand-held tools, the advantage of laser engraving machine is that the engraving characters and patterns can be controlled, the size can also be controlled, and the engraving patterns are relatively fine. The disadvantage is that it is not as three-dimensional as the manual physical carving. 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 laser engraving machine to achieve the function of engraving, mainly need software to control the mechanical transmission of laser light source several major components to achieve, in which the software as a human-computer interaction page, used to edit pictures and text, adjust parameters and start and stop. The traditional engraving machine is driven by a stepper motor or a servo motor through a mechanical transmission part, of course, due to the characteristics of 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, and the characteristics of the light source determine the material effect of the laser engraving. The amount of energy has a significant impact on the depth and speed of carving.
Learn about laser engraving machines
I believe that many friends who want to buy laser engraving machines are most concerned about this issue. Everyone must want to choose a practical and economical type of laser machine. So before choosing, you can understand the advantages and disadvantages of various laser machines.
CO2 laser engraving machine: Advantages: wide range of engraving materials such as wood, leather, plastic, rubber, etc., high power, fast engraving speed and high precision. The disadvantage is that the machine is heavy and generally 40-50 kilograms, the price is moderate, and the product is large and suitable for factories. Price $2000-$20000
Fiber laser engraving machine has the advantages of high engraving precision and fast speed, which is suitable for batch operation in the factory and can be connected to the factory automation production line. The disadvantage is that the machine is generally more expensive, about $3000, the volume is relatively large, and the weight is more than 30 kilograms
Purple laser engraving machine, advantages: a wide range of engraving materials, both metal and non-metal can be engraved. And one machine can be use for multiple purposes. The disadvantage is that the price is expensive, because of the characteristics of purple light source, the machine is generally more than $20,000-$30,000, and the machine is relatively heavy. Applicable to high-end manufacturing industry
The green laser engraving machine has the advantages of three-dimensional engraving and three-dimensional positioning engraving. The disadvantage is that it is bulky and expensive.
The diode laser engraving machine has the advantages that the price is as low as below $1000, generally not higher than 800 yuan, and the volume is small and convenient to move. The disadvantage is that the carving speed is slow and pure metal can not be carved. Because of the speed limit, it is generally more suitable for personal DIY household use, or small and medium-sized businesses to customize in small batches.
