Waterjet Cutting Machine PSI 120,000: The Ultimate Guide to Precision Cutting

Waterjet cutting machines have revolutionized industrial manufacturing with their ability to cut through almost any material with precision and versatility. Operating at pressures up to 120,000 PSI, these machines combine high-pressure water with abrasive substances to deliver unparalleled cutting capabilities. This comprehensive guide explores the technology, applications, and technical specifications of waterjet cutting machines.

Comparison of Waterjet Cutting Machine Types and Applications

The Science Behind Waterjet Cutting Pressure

Waterjet cutting machines operate on a simple yet powerful principle – the conversion of water pressure into kinetic energy. At 120,000 PSI, the water stream travels at speeds exceeding Mach 3, creating a force capable of cutting through materials with surgical precision. This pressure is achieved through advanced pump technology, typically using intensifier pumps that multiply hydraulic pressure.

The pressure of 120,000 PSI is equivalent to:
– 8,274 bar
– 827.4 MPa
– 1,743 atmospheres

This immense pressure allows waterjet machines to cut through materials up to 12 inches thick, depending on the material type and abrasive used.
