Key Components of a Laser Cutting Machine

Composed by many parts, each component plays an essential role during the cutting.

• Laser Source
• Control System
• Mechanical Bed
• Cutting Head
• Automatic Lubrication

Laser Source

As the main component, the laser source is responsible for high-power-density laser beam generation. Commonly, laser sources include CO2 lasers, fiber lasers and YAG lasers. The laser source should be decided on the thickness and type of materials to be processed.

Control System

The control system manages and coordinates the rest parts of a laser cutting machine. It commonly includes a CNC system which is used to control paths and cutting speed of laser beams precisely. An advanced control system allows for automatic and intelligent operation, improving productivity.

Mechanical Bed

As a platform to put materials to be cut, a Mechanical bed entails high stability and precision to ensure the materials remain stationary during cutting. The design and material of mechanical bed affects cutting quality significantly.

Cutting Head

The cutting head is the part where laser beams contact with the materials. It normally includes focusing lenses and a nozzle whic h focuses laser beams on the material surface.

Assisted by sprayed gases, the molten and evaporate materials will be blown off the working area. The design and maintenance for cutting heads are vital.

Automatic Lubrication

Automatic lubrication is used to maintain the best working performance of a laser cutting machine's moving components. Regular lubrication can eliminate wear and tear, prolong the equipment's lifespan, and improve cutting efficiency and accuracy.

In summary, laser cutting machines are vital tool for modern manufacturing. The choice of their types and key components directly affects productivity and product quality.
