A Quick Review of Water Cut Technology

I know what you are thinking. How did they pull this one off, and how on earth am I supposed to believe that water cut technology is better than other methods?

Well, you’re exactly right. The idea of water being able to cut metal sounds absurd.

Nevertheless, it seems Flow has pulled off something magnificent here. We thought you would be interested in taking a look at this, so we decided to write a quick review.

Apparently, not only can water cut through anything from modern metals to highly engineered materials, but it can do it better than any other method!

If you keep reading, we will give you a brief review of water cut technology. More importantly, we will go over some of the benefits of using water over traditional cutting methods.

Hopefully, this review will help you understand why cutting your materials with water could be the best option for you.

How Does Water Cut Technology Line Up with Other Cutting Methods?

In this study by Daniel Krajcarz of Kielce University of Technology in Poland, three different technologies were put to the test. Mr. Krajcarz put water cutting technology up against plasma and laser cutting metal, all separately.

Water cutting technology outperformed the other two technologies by a long shot. In his summary, Mr. Krajcarz concludes that water is the most efficient way to cut metal out of the three technologies.

Mr. Krajcarz stated that his determinations were based on a number of factors. For one, there are no limitations when cutting through metal with water, or any other material for that matter, because water cutting is not held back by conductivity or light.

In this chart, water cutting technology was compared to all of the main known cutting methods including; wire EDM, laser, plasma, milling, and punch press. Amazingly, cutting with water either matches or outperforms other methods on most instances.

On the instances where water cut technology was outdone, it wasn’t by much. So, bottom line, by the time you add in some of the benefits that you can only get from cutting with water, not only could you call water cutting metal possible... You could call it a superior method!

How Does this Technology Work?

Good question. Water cut technology works by first generating a ton of water pressure. (around 94,000 psi)

Then, the water is sent through a tiny jewel orifice, where it is converted into velocity. This creates a stream of water as thin as a human hair.

After that, garnet is pulled in with the water stream to intensify the cutting power of the water by 1,000 times!

Lastly, the garnet and water solution exit the cutting head at nearly 4X the speed of sound. This combination of velocity, water pressure, and garnet is capable of cutting through nearly a foot of steel.

Pretty amazing, right? Well, that’s not all!

Options to Buy Waterjet Machines

The water jet comes in an array of sizes so that you can buy the one that best accommodates your needs. Check out some of your options here:

Mach 2b

This is the most cost-effective model of the waterjet series. It outperforms other waterjets in its class, and it is built tough to withstand your heaviest productions.

The Mach 2b is made of solid steel with a high-end ball screw and digital drive motion system for accuracy that can’t be matched.

Mach 200

Efficient, practical, and powerful, the Mach 200 is a superior cutting machine. It’s job… Delivering the efficiency and power of the elite water jets, in less space.

With 3 sided access for easy access both loading and unloading, the Mach 200 comes with a compact cutting head made to handle 5-axis cutting with taper control.

Bottom line, is you get accuracy, speed, and agility in a smaller package.

Mach 300

If you need a small water cutting machine that will quickly pay for itself, but you do not want the smallest one, this is your machine.

The Mach 300 is designed to get large jobs done while minimizing shop space and maximizing value.

This is the best option for shops with limited space and high workloads.

Mach 500

Said to be the most productive solution, the Mach 500 is the fastest, quickest and most accurate waterjet in its class. This is where you drop the ball and pick up a whole new game.

The Mach 500 is paired with Dynamic SD and Compass technologies… Literally guaranteed to surpass any expectations of quality.

No other cutting machine near this capacity can touch the Mach 500.

Mach 700

If you need a machine for heavy industrial production, you need the Mach 700. Just enough to get the job done, and amply fit for continuous workloads.

Made of all steel construction, the Mach 700 is made to handle 24/7 workloads with ease.

With a helical rack and pinion drive system, the Mach 700 moves quickly and seamlessly through its workload.

The Mach 700 includes a roll around workstation that gives you the control over your projects that you only can get from having 360? access.


The NanoJet is a groundbreaking, quiet, and precise cutting environment. This model is enclosed, to keep your work environment focused and safe from the rest of the world.

This is the best machine on the market for jobs that require complex geometrics.

If you need your up-time to be constant and uninterrupted, and a cutting-edge machine that is fast, reliable, and predictable, you want the NanoJet.

Final Thoughts

Flow is a Shape Technologies Group Company. They are the world leader in sales and the inventor of the waterjet. This technology is not only cutting edge, but it is built to conquer the fabrication and manufacturing industries.

One of the reasons why waterjet is more than enough to do the job is because the water cut technology is designed by people that understand that you need this technology to fill a need.
