Metal waterjet cutting is a process that uses a high-pressure stream of water mixed with abrasive particles to cut through metal. Here's a simple explanation:

Waterjet System:

A waterjet cutting system includes a high-pressure pump, a mixing chamber, and a nozzle.

Abrasive Water Mixture:

Abrasive particles, usually garnet or aluminum oxide, are mixed with pressurized water in the mixing chamber.

High-Pressure Pump:

The pump generates extremely high pressure, forcing the abrasive water mixture through the nozzle.

Focused Cutting Stream:

The waterjet stream, now containing abrasive particles, is focused into a narrow beam for precision cutting.

Metal Cutting:

The high-speed abrasive waterjet cuts through the metal, creating the desired shapes or patterns.


Waterjet cutting can be used on various metals, including steel, aluminum, and titanium.

Cold Cutting:

Unlike traditional methods, waterjet cutting is a "cold" process, meaning it doesn't generate heat that could affect the metal properties.


Commonly used for cutting metal sheets, plates, and intricate shapes in industries like aerospace, automotive, and fabrication.

In simple terms, metal waterjet cutting uses a high-pressure stream of water mixed with abrasives to precisely cut through metal, offering versatility and maintaining a "cold" cutting process.
