Advanced fabrication, therefore, is not just an advantage but a necessity for Australian PEB companies aiming for excellence and sustainability in a competitive market.
Understanding Laser Cutting Technology
Laser cutting is a thermal cutting process that uses a focused high-power laser beam to melt, burn, or vaporize material in a localized area. The process is guided by computer numerical control (CNC), ensuring unparalleled accuracy and repeatability. This technology offers a non-contact method of cutting, minimizing material distortion and achieving clean edges.
How Laser Cutting Works
A laser cutting machine directs a concentrated beam of light through optics to a focal point on the material’s surface. The intense heat generated at this point rapidly melts or vaporizes the material. Simultaneously, an assist gas, such as oxygen or nitrogen, is blown coaxially with the laser beam. This gas helps to eject the molten material from the cut kerf and also protects the optics from debris.
The CNC system precisely controls the laser head’s movement across the material, following the programmed cutting path. This digital control ensures that complex geometries, intricate patterns, and precise holes are cut with exceptional fidelity to the original design file.
Types of Laser Cutting Machines Relevant to PEB
