CO2 Laser Cutting Machine

A CO Laser Cutting Machine is a precision-based, non-contact cutting and engraving system that uses a high-powered carbon dioxide laser beam to cut, engrave, and mark various non-metal and selected coated metal materials. It is widely used in industries such as advertising, packaging, textile, leather, woodworking, and signage.

Working Principle
The machine operates by generating a laser beam inside a CO laser tube filled with gas mixture (CO, nitrogen, helium).

• The laser beam is directed through mirrors and focused using a lens.

• A high-intensity focused beam melts, burns, or vaporizes the material.

• A motion control system (CNC-based) guides the laser head along the programmed path for accurate cutting or engraving.
