The Power of Metal Cutting Laser
Laser cutting has emerged as a game-changer in the metal fabrication industry, offering unparalleled precision and efficiency. Let's explore how this technology works and why it's the preferred choice for many applications.
How Laser Cutting Works
Laser cutting is a thermal separation process that uses a focused laser beam to heat a metal workpiece to the point of melting or vaporization. A high-pressure gas (such as oxygen, nitrogen, or compressed air) is then used to blow the molten material out of the kerf, creating a clean cut.
The laser beam is generated by a laser resonator and directed through a series of mirrors or fiber optics to the cutting head. The cutting head focuses the beam to a very small spot size, typically between 0.1 and 0.5 mm, creating intense heat that can melt or vaporize even the toughest metals.
Key Components of a Laser Cutting System
- Laser Source: Generates the high-powered laser beam
- Beam Delivery System: Guides the laser beam to the cutting head
- Cutting Head: Focuses the beam and delivers the assist gas
- CNC Controller: Directs the movement of the cutting head
