Why does a laser cutting machine need a dedicated air compressor?

air compressor for laser cutting

Laser cutting machines rely on a dedicated air compressor for several crucial reasons:

  1. Assisting the Cutting Process

    • Laser cutting involves using a high-power density laser beam to concentrate light onto a small spot, rapidly heating the material until it vaporizes and forms a cavity.
    • The compressed air plays a vital part in blowing away smoke and debris generated during the cutting process.
    • By keeping the cutting area clear, it ensures clean and precise cuts.
  2. Enhancing Cutting Quality

    • The air assist provided by the compressor improves the overall quality of laser cutting.
    • It helps prevent charring, scorching, or discoloration of the material by removing excess heat and debris.
    • Clean air assists in achieving smooth and attractive surfaces on the cut pieces.

  3. Cooling and Stabilizing the Laser Head

    • The laser head can become hot during prolonged cutting sessions.
    • The compressed air helps cool down the laser head, preventing overheating and maintaining stable performance.
    • It also purges and cleans the optical system, ensuring optimal laser beam quality.
  4. Non-Contact Process:

    • Laser cutting is a non-contact method, meaning there’s no physical contact between the nozzle and the workpiece.
    • The air compressor eliminates the need for direct nozzle-to-material contact, reducing wear and tear.
  5. Choice of Auxiliary Gases:

    • Depending on the material being cut, different auxiliary gases (such as oxygen, nitrogen, and compressed air) are used.
    • Compressed air is a versatile choice, especially for materials where nitrogen or oxygen may not be suitable.
    • It provides a cost-effective alternative while maintaining cutting efficiency

Scroll compression principle Compressor sucks air through air inlet located at outer scroll.Compression chamber goes smaller with rotary movement and trapped air is compressed.Compression chamber becomes minimum volume at the center of the scroll and air is pumped out through air outlet located at the center of scroll.These, suction, compression & discharging, process is repeated continuously. Long maintenance cycle with long life consumable parts. Compressor head replacement at every 10,000 hours or 4 years whichever comes earlier. Scroll oil free screw air compressor, 100% oil free for food industry, dental and medical industry.
