Metal & Nonmetal Co2 Laser Cutting Machine

A metal laser cutting machine works by utilizing a high-powered laser beam to cut through metallic materials. The process involves several key steps:

• Beam Generation: The laser cutting machine generates a high-powered laser beam using a laser resonator. This resonator contains a laser medium, such as carbon dioxide (CO2) or fiber, which is excited by an energy source, such as an electrical discharge or diode.

  
  

• Beam Delivery: The laser beam is then directed through a series of mirrors and lenses to focus and control its intensity. These optical components ensure that the laser beam is precisely delivered to the cutting area.

  
  

• Material Interaction: The focused laser beam is directed onto the surface of the metal material being cut. The intense heat of the laser beam rapidly heats the metal, causing it to melt, burn, or vaporize. The laser beam is typically pulsed or modulated to control the amount of energy delivered to the material.

  
  

• Assist Gas: To enhance the cutting process, an assist gas, such as oxygen or nitrogen, is often used. This gas is directed through a nozzle near the laser beam, blowing away the molten or vaporized metal and creating a clean cut.

  
  

• CNC Control: The entire cutting process is controlled by a computer numerical control (CNC) system. The CNC system precisely controls the movement of the laser beam and the positioning of the metal material, ensuring accurate and repeatable cuts.

The combination of the high-powered laser beam, precise beam delivery, material interaction, and CNC control allows metal laser cutting machines to achieve fast, precise, and clean cuts in various types and thicknesses of metal materials.
