Among many laser engraving machines, carbon dioxide (CO2) laser engraving machines are popular because of their excellent performance in non-metallic material processing. This blog will give you a detailed introduction to the characteristics and advantages of CO2 laser engraving machines and how to choose the best CO2 laser engraving machine.

The Basic Principle of CO2 Laser Engraving Machine

The working principle of CO2 laser engraving machine is based on the interaction between laser beam and material. The laser beam is transmitted and focused through the optical mechanism to form a focus with high energy density on the surface of the material. When the laser beam acts on the material, due to the extremely high energy density, the material will quickly vaporize at the focus to form a pit point. The computer controls the X-Y console to drive the laser head to move, and controls the switch of the laser according to the preset path to achieve accurate engraving of the material.

Key components

  • Laser: The core of the CO2 laser engraving machine is the CO2 laser, which generates glow discharge through CO2 gas filled in the high-voltage discharge tube, so that the gas molecules release laser. The laser converts electrical energy into laser energy to generate a high-energy laser beam.

  • Optical path system: The optical path system is responsible for accurately guiding and focusing the laser beam to ensure that its high energy is concentrated and accurately acts on the surface of the material.
  • Control system: The control system is the brain of the laser engraving machine, responsible for manipulating the operation and processing of the entire equipment, including setting processing parameters, running trajectory and monitoring processing effects.
  • Workbench: The workbench provides a fixed platform for accurate positioning and fixing of materials.
  • Cooling system: Since the laser generates heat during operation, the cooling system is responsible for heat dissipation to ensure the normal working state of the laser.
    Power supply system: The power supply system provides the required high-power electrical energy for the laser to drive the laser to work.

Working process

During the working process, the CO2 laser engraving machine first generates a laser beam through the laser, and then guides the laser beam to the focusing lens through the optical path system. The focused laser beam acts on the surface of the material and engraves according to the path controlled by the computer. The information stored in the computer is in binary, which is consistent with the two states of the laser switch, so as to achieve precise engraving effects.

Technical parameters and performance indicators

  • Laser power: La potencia del láser afecta directamente la profundidad y velocidad del grabado.. The power range of CO2 laser engraving machines is usually between 30W and 200W. Higher power can handle thicker materials, but may reduce the accuracy of some materials.
  • Área de grabado: The engraving area determines the size of materials that the machine can handle. Common working area sizes are 600×400 milímetro, and there are larger sizes such as 1250×2550 milímetro. Choose the appropriate size according to your work needs.
  • Velocidad de grabado: The engraving speed affects the processing efficiency, and the speed ranges from 0.1mm/s to 3000mm/s. When purchasing, you should choose the appropriate engraving speed according to your processing needs and budget. High-speed engraving can improve production efficiency, but the stability and accuracy of the machine should also be considered.
  • Minimum line width and accuracy: Accuracy and minimum line width determine the level of detail that the machine can handle. The engraving accuracy can reach ±0.05 milímetro, and the minimum line width can reach 0.1 milímetro.
  • Cooling system: Most CO2 laser engraving machines use a water cooling system to keep the temperature of the laser tube stable and extend its service life.
    6. Beam size: The beam size affects the fineness of the engraving, generally between 1.5-2.0 milímetro.
  • Supported file formats: Check whether the machine supports your commonly used design file formats, such as BMP, JPEG, GIF, TIFF, PNG, AI, DXF, PLT, etc..
  • Control system: Some machines may come with laser engraving software and need to be compatible with Windows or Mac OS operating systems.
  • Connection method: Check the machine’s connection method, such as USB interface, to ensure compatibility with your computer system.
  • Power requirements: Make sure the machine’s power requirements match your power supply, usually AC 220V/50Hz.
  • Equipment size and weight: Consider the physical size and weight of the machine to ensure it fits your workspace.
  • Repeatability: This determines the consistency of the machine when engraving the same pattern multiple times, generally within ±0.1 milímetro.
  • Laser tube cooling: Forced water cooling (industrial chiller) can cool the laser tube more effectively, improve stability and efficiency.
  • Mechanical resolution: The mechanical resolution determines the positioning accuracy of the machine, como 0.025 milímetro.
  • Cutting depth: Depending on the material, the cutting depth will also vary, such as acrylic can reach 30 milímetro.
  • Speed control: The speed control can be 0-100% stepless control to adapt to different engraving needs.
  • Laser energy control: Two modes are optional: software control or manual adjustment to adapt to different materials and engraving depths.
