Water Jet Machining

Introduction to Water Jet Machining

Water jet machining is a non-traditional machining process that uses a powerful stream of high-pressure water — sometimes combined with abrasives — to cut through various materials with remarkable precision. Unlike conventional cutting methods, it does not rely on heat or mechanical force, making it ideal for applications where material integrity must be preserved.

The core components in this process include a high-pressure pump that pressurizes the water, an intensifier to maintain consistent pressure, a specialized nozzle that focuses the water jet, and an abrasive system when cutting tougher materials like metals or composites.

Since its evolution in the 1970s — from initial use in cleaning to today’s precision cutting services — water jet machining has become a go-to solution for industries needing clean, exact cuts without heat-affected zones. This includes everything from aerospace components to custom metal fabrication.

Why Choose Water Jet Machining

Precision Eco-Friendly Water Jet Cutting

Water jet machining stands out for its ability to cut diverse materials—including metals, glass, and composites—with unmatched precision. Unlike laser, EDM, or plasma cutting, this non-thermal machining process preserves material integrity by avoiding heat-affected zones and thermal distortion. The thermoneutral nature of water jet cutting ensures parts hold tight tolerances of ±0.1 mm, ideal for critical applications.

No heat-affected zones – keeps your parts stable
Eco-friendly machining with minimal waste
Cuts a wide range of materials, from metals to composites
Precision tolerances of ±0.1 mm for reliable results

For advanced manufacturing needs, water jet machining complements other CNC processes perfectly. Whether you need abrasive water jet machining for thicker materials or fast CNC water jet cutting, this technology is a top pick for precision cutting services across industries. Learn more about how water jet compares with other cutting techniques in our detailed guide on laser, plasma, and waterjet CNC cutting methods.

How Water Jet Machining Works

Water jet machining uses a high-pressure stream of water—pressurized up to 400 MPa—to cut and shape materials with unmatched precision. In abrasive water jet machining, the water mixes with abrasive particles that erode the material surface, creating clean cuts without heat damage.

Water Pressurization: Water is pressurized up to 400 MPa for maximum cutting force.
Abrasive Mixing: Abrasive particles blend with the water jet for cutting harder materials.
Material Erosion: The high-energy jet erodes away the target material, producing precise cuts.

We use pure water jets for softer materials like rubber or foam, providing a clean, non-thermal machining method that avoids warping. For metals and harder surfaces, abrasive water jet machining (AWJ) is ideal—combining water and abrasive media to cut through metal and composites effortlessly.

Key Parameters Affecting Performance

Water jet machining relies on a high-pressure stream of water—often mixed with abrasive particles—to cut materials with exceptional precision and no heat damage. The process is fully controllable through several key parameters that determine cutting efficiency and quality:

  • Traverse Speed: Dictates how quickly the cutting head moves; affects surface smoothness and cutting time.
  • Hydraulic Pressure: Higher pressure increases cutting power and can cut denser metals or thicker materials.
  • Stand-Off Distance: The gap between the nozzle and material surface; impacts kerf width and accuracy.
  • Abrasive Type & Flow Rate: Choosing the right abrasive and its flow ensures consistent material removal and finish quality.

These parameters together influence the material removal rate, surface roughness, and kerf width, making water jet machining a versatile, non-thermal machining option for metals, composites, and delicate materials.
