Various parts machined with an abrasive jet

Pictures of various items cut with an abrasive waterjet from various materials

The key word to describe a waterjet is "versatile." In the above picture, notice the wide variety of shapes created by the waterjet, as well as the different thicknesses. notice also the range of materials shown--various metals, Plexiglas®, even granite.

Various thick parts machined with an abrasive jet

Pictures of various large parts machined on an abrasive waterjet

Parts in the above picture are up to  4" (10 cm) thick. Again, note the variety fo shapes possible with waterjet machining.

Brass spring machined with an abrasivejet

A spring machined from 1/8" (3 mm) brass

Despite the long tool path, the spring shown in the above picture only took about 10 minutes to machine.

The file shown in the above picture is made of hardened steel. With most machining tools, hardened steel takes considerably longer to cut than regular steel. With a waterjet, hardened steel takes only slightly longer to machine. This lets manufacturers harden their materials before cutting, which can be more efficient and cost-effective.

Rack and gear machined with an abrasivejet

While etching is not the strong suit of waterjets, it can be done. The above photographs show two samples of etching. For the friction plate, the speed of the waterjet head was rapid enough that the material didn't cut all the way through. The etching in the glass on the right was done using low pressure, again so that it wouldn't cut through the material.

Etching works best with hard materials, although even then, it is difficult to get a consistent, even depth with a waterjet.

Waterjets generate very small side forces as they maching. Most of the energy is directed straight down on the material. As a result, it is possible to make parts with very thin features, such as the cheese cutter shown above where the blade is less that 0.020" (0.5 mm) thick.

Honeycomb machined with an abrasive waterjet

Another example of thin wall cutting in ½" (13 mm) aluminum

The walls in the above honeycomb piece are about 0.025" (0.6 mm) thick. Note the uniformity of the walls as well as their thinness.

Fine tooth gear and rack machined with an abrasive waterjet.

Tiny puzzle cut with a waterjet

Jigsaw cut from wood with a pure waterjet

Note the very small size of the total part. The narrow kerf width of a pure waterjet allows for this type of machining. The drawback to a pure waterjet is that it is efficient only for very soft or thin materials.

If you have pictures you would like to share about something you made on a waterjet, send them by with a short description of what it is, what it is made of, and any notes on how it was made.
