About Waterjet Cutting

Waterjet, also known as water jet or abrasive jet cutting, is one of our machining processes that directs a high-pressure jet of water and an abrasive substance to cut materials for industrial applications such as machine part manufacturing. Modern water jet cutters are controlled by CNC (Computer Numerical Control) systems running G-code to position the water jet nozzle and increase accuracy.

Important benefits of water jet cutting with an abrasive substance include the ability to cut metals without increasing the material surface temperature and compromising internal structure of the material (no Heat Affected one, or HAZ); the ability to cut sharp corners, holes, and complex shapes with small inner radii; fast turn-around rates; and minimal material waste thanks to the precise cutting and the narrowness of the nozzle.


No effects from heat
  • Cutting with a water jet is a non-contact form of processing. No drills or other tools touch the object, so no heat is produced, and there is absolutely no alteration to the object or changes in color.
No limit to the objects that can be targeted
  • Because cutting is performed with an extremely small volume of ultrahigh-pressure water, there is very little water on the cutting surface. As with laser cutting, there are no limits to target objects.
Facilitates cutting with shapes
  • Cutting and cutting out of any shape, from any point.Cutting is possible for three-dimensional bodies, as well as two-dimensional shapes.
Environmentally friendly
  • No dust is produced, so there is no impact on workers or the environment.
    In addition, processing can be performed with water and sand (abrasive materials) only, so it is environmentally friendly.


A waterjet utilizes a high-pressure stream of water to erode a narrow line in the stock material. To cut a wider range of materials from tool steel to titanium to foam, a granular (typically garnet) abrasive is added to the waterjet, increasing the cutting power. Because the abrasive is added at the nozzle, it is simple to switch between water only and abrasive waterjet cutting. This flexibility greatly enhances the versatility of a waterjet machine, as it can easily switch from cutting ½” (1.27cm) foam gaskets to 4″ (10.16cm) titanium brackets.

To cut a wider range of material, a granular abrasive (typically garnet) is added to the high-pressure waterjet stream, increasing the cutting power. Because the abrasive is added at the nozzle, through the mixing tube, it is simple to switch between water only and abrasive waterjet cutting.

Applications for Waterjet


Sheet metal offers a cost-effective way to fabricate product device panels, boxes and cases for a variety of applications. We build enclosures of all styles, including rackmounts, “U” and “L” shapes, as well as consoles and consolets.


The chassis we fabricate are typically used to house electromechanical controls, from small handheld devices to large industrial testing equipment. All chassis are built to critical dimensions to ensure hole pattern alignment between different parts.


We build custom brackets and miscellaneous sheet metal components, well-suited for either lightweight applications or when a high degree of corrosion-resistance is needed. All hardware and fasteners that are needed can be fully built in.

Overview: What is Waterjet?

The Basics Of Waterjets:

A waterjet cutter, also called a waterjet, is an industrial cutting device used for the fabrication of flat-cut parts. Using a nozzle to focus water into a high-pressure stream, a waterjet can be used to cut semi-soft materials like rubber, foam, or wood. Abrasive granular substances can be added to the jet in order to cut harder materials like aluminum and sheet metal.

How does Waterjets Work?

A waterjet is connected to a high-pressure pump, which pushes water through specialized tubing and then expels it from the nozzle at a focused volume and a velocity of up to 900 m/sec. The perfect ratio of velocity and volume is what allows the waterjet to maintain it’s a unique high-pressure cutting stream.

In the case of abrasive water cutting, the abrasive substance (often garnet or aluminum oxide) is combined with the water in a chamber near the nozzle, and the mixture is then ejected in a thin water stream.

A waterjet is given great accuracy and repeatability by CNC technology, which is able to reliably manage the movement of the nozzle and water.

What about the components of a waterjet cutter?

The waterjet cutting machine system consists of three basic components:

The Pump:

The high-pressure pump provides pressurized water for the cutting process.

The Controller:

The controller uses software for system operation, motion control, and nozzle positioning.
