The Technology Behind Metal Laser Cutting
Metal laser cutting machines employ the principles of laser technology to cut, engrave, or mark metal materials. The key components of these machines include:
Laser Source: The heart of the machine is the laser source, which emits a high-intensity laser beam. Common types of lasers used in metal cutting machines include CO2 lasers and fiber lasers. Fiber lasers, in particular, have gained popularity for their speed and efficiency.
Focusing Optics: The laser beam is directed and focused onto the workpiece’s surface through a series of mirrors and lenses. Precise focus is crucial for achieving clean and accurate cuts.
CNC (Computer Numerical Control) System: The machines are controlled by computer programs that translate designs into precise cutting instructions. This allows for intricate and complex patterns to be created with ease.
Worktable: The workpiece is placed on a worktable that can move in multiple axes. This movement, controlled by the CNC system, ensures that the laser beam accurately follows the desired cutting path.
Assist Gas System: Assist gases, such as oxygen, nitrogen, or compressed air, are used to aid in the cutting process. These gases help remove molten material and debris from the cutting area, resulting in clean cuts.
