Abrasive waterjet pump technology continues to evolve toward higher pressures. Within the pump’s design limits, the higher the pressure, the faster the abrasive moves, and the faster you can cut.

Many of today’s cutting applications require surgical-like precision to produce small, intricate parts. Technological advancements in waterjet and laser cutting are making these processes even more attractive to fabricators in a variety of industries.

Because shipping spent waterjet abrasive off to the landfill usually is easy, not too much thought is given to attempting to recycle it. However, in today's manufacturing world, all aspects of the operation are scrutinized for possible cost savings. That includes looking at abrasive recycling.

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.

After having purchased waterjet cut parts as part of his old job, Dan Sarmiento thought he could develop a better waterjet cutting system. He had his handiwork on display at FABTECH 2015.
Knowing the basics of waterjet pumps allows a fabricator to figure out just what technology makes sense for the work on the shop floor and just what type of commitment is necessary to run that pump technology successfully.

Rando Productions juggles various projects from various customers—TV shows, commercials, theme park attractions—and each has its own timeline. It’s all one-off, nonrepeat work. Sound familiar?

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.

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.

Waterjet nozzle technology has progressed to the point where the cutting of parts and part features smaller than 0.012 in. is now possible.

When John Force Racing took most of its manufacturing operations in-house in the early 2000s, the focus was on controlling quality and lead time. However, it didn't have a quick-response fabricating tool for 2-D cutting. It has since found that tool with its new waterjet

Currently used primarily in art and architecture, waterjet etching is beginning to make inroads into machining and fabricating shops. The textured gripper pictured in this article is an example of a 3-D etched part.

Five-axis waterjet cutting is not something you see in every fabricating operation. But for some applications where tube or precise edge cutting might be required, it makes total sense.

Once custom-produced on a one-off basis for specific applications, large abrasive waterjet cutting tables have become part of many standard systems, thanks mostly to advanced linear-drive technology that makes the machines more affordable.
