Right-size your waterjet cutting machine

April 27, 2016 | By Jim Fields

Most fabricators choose waterjets with large work envelopes because they process large parts, but there’s a productivity element to consider as well, especially when it comes to material loading/unloading. Myriad other factors play a role, too, including horsepower and the number of cutting heads.

Selecting the right waterjet abrasive

September 8, 2014 | By R. Randolph Rapple

Almost every natural and synthetic material has been tried as a waterjet cutting abrasive. The best material appears to be almandine garnet. However, it's the right combination of hardness, density, toughness, and particle shape in the garnet that maximizes a waterjet's cutting capabilities.

Reusing recycled abrasives in waterjet cutting?

August 7, 2014 | By Dan Davis

When it comes to waterjet cutting, most metal fabricators rely on virgin garnet as the abrasive that’s used in conjunction with the waterjet stream. After cutting is concluded, the abrasive can be collected and recycled as a filler for other construction-related products. An Auburn, Wash.-based company, however, thinks it has found a way to take the recycled material and return it to an almost-new state.
