Light source classification and selection criteria of laser engraving machine
Laser engraving machine, also called laser engraving machine, is a technological equipment that uses laser to engrave materials that need to be engraved. 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, the engraving efficiency is also very different.
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 relatively high density.
The purple light source is a relatively high-end light source with very fine carving and a wide range of carvings.
Green light source, we may have seen a lot of three-dimensional images in the middle of acrylic, which are generally carved by green light source, which can engrave transparent glass and other materials.
The diode light source, which was originally a stage lighting light source, has achieved a magnificent turn in the laser engraving industry. Its engraving principle is a bit similar to lighting a cigarette butt under the sun of a magnifying glass.
Selection criteria of laser engraving machine
I believe that many friends who want to buy a laser engraving machine are most concerned about this issue. Everyone definitely hopes to choose a practical and economical laser machine type. Therefore, you can understand the advantages and disadvantages of various laser machines before choosing, so as to choose the right type.
CO2 laser engraving machine
Advantages: Engraving materials are widely used in wood, leather, plastic, rubber, etc., with high power, fast engraving speed and high precision.
Disadvantages: The machine is bulky and generally weighs between 40-50 kg, which is not convenient to move, and the price is generally moderate, suitable for factory use.
Fiber laser engraving machine
Advantages: high engraving accuracy, fast speed, suitable for factory batch operation, and can be connected to factory automation production lines.
Disadvantages: The machine is generally more expensive than about 15,000 yuan, and the volume is relatively large and the weight is more than 30 kilograms.
Purple laser engraving machine
Advantages: wide engraving materials, both metal and non-metal can be engraved. One machine can be used for multiple purposes.
Disadvantages: The price is expensive. Because of the characteristics of the purple light source, the machine is generally more than 20,000 to 30,000 yuan, and the machine is also relatively heavy. Suitable for high-end manufacturing.
Green laser engraving machine
Advantages: It can realize three-dimensional engraving and three-dimensional positioning engraving. Disadvantages: It is also bulky and expensive.
Diode laser engraving machine
Advantages: The price is as low as 1,000 yuan and generally not higher than 3,000 yuan, and it is small in size and convenient to move.
Disadvantages: The engraving speed is slow, and pure metal cannot be engraved. Due to speed limitations, it is generally more suitable for personal DIY home use, or small batch customization by small and medium businesses.
