Fiber Laser Cutting Machine

Fiber Laser Cutting Machine About

A Fiber Laser Cutting Machine is a CNC (Computer Numerical Control) machine that uses a high-power fiber laser beam to cut various metals with exceptional precision, speed, and edge quality. It is widely used in industries such as sheet metal fabrication, automotive, aerospace, electrical panels, kitchen equipment, agricultural machinery, and custom metal fabrication.

Working Principle

A fiber laser cutting machine works by:

1. A fiber laser source generates a high-intensity laser beam.
2. The laser beam is transmitted through an optical fiber to the cutting head.
3. A focusing lens concentrates the beam into a tiny spot.
4. The focused beam melts or vaporizes the metal.
5. An assist gas (Nitrogen, Oxygen, or Compressed Air) blows away the molten material.
6. The CNC system moves the cutting head according to the programmed design
