What Is Waterjet Cutting?

Waterjet cutting is a process where high-pressure water, often mixed with abrasive particles, is directed through a nozzle to cut through materials like aluminum. Unlike traditional cutting methods, waterjet cutting does not rely on heat, making it ideal for materials sensitive to thermal distortion.

  • Key components of a waterjet cutter:
  • High-pressure pump
    • Abrasive hopper
    • Nozzle
    • Control software
