What are the Most Popular Water Jet Cutter Myths That Need Debunking Today?

Water jet cutter is suitable for cutting and slicing through metal, polymers, as well as carbon fiber without any worries of risk of distortion or warping. As the popularity of waterjet-based cutting has grown over the years, so has the number of myths and misconceptions about the technology, leaving many people confused about the true material cutting and slicing potential of waterjet machines.

To debunk these myths due to their ill effects on interested parties, we’ve prepared this piece to help you understand the process even better and thus make a better judgment for yourself.

Myth: Abrasive jets are slow and inefficient.

We understand why some people believe that waterjet cutting results take a long time and effort to achieve, but a waterjet-based material-cutting system uses an accelerated erosion process to slice and cut through an object in a very short period. Many people are surprised to realize that despite its fast cutting speed, it will not create a mess and will not even produce noise.

While cutting above water can generate about 95-decibel sounds, cutting your material underwater produces just 75-decibel sounds.

Myth: Waterjet Cutting Machines are not designed to cut complex parts.

People have been led to believe that waterjet machines are incapable of cutting and slicing precise three-dimensional components. However, recent cutting-edge enhancements in 3D cutting technology have laid the foundation for an increased level of adaptability. 

Waterjet systems can process the cutting of sophisticated objects 3D in a single fluid motion. This is made possible by utilizing a cutting head that swerves in multiple directions. Its control and maneuver can be done with the help of powerful software. Hence, the need for a secondary cutting procedure is taken out of the equation here and is no longer necessary. 

Myth: Waterjet Systems Run the Risk of Blowing Up

If your pump came from a reputable brand, there is absolutely no reason for you to be concerned about this. Think about this: compared to air, there is no possible way you can compress water. Therefore, it makes sense that a water jet pump contains significantly less energy than a scuba tank.

Throughout the design process of the high-pressure pump, manufacturers must adhere to stringent laws and industry standards. One cornerstone of these regulations ensures that every high-pressure vessel is engineered to leak before it ruptures. This type of design keeps pressure from building up in places that are vulnerable to catastrophic failure.

Myth: It is More Efficient to Use Lower Pressure Cutting

This particular myth about waterjet systems has been spread far and wide. Over the years, waterjets have undergone a radical transformation to utilize more pressure, since they tend to perform an exceptional job at higher pressures. 

It’s the first time in the history of waterjet that we’re witnessing a consistent trend towards lowering pressure, yet, every single time a new groundbreaking machine is introduced to the market with a higher pressure level, our natural inclination is to resist change (which is completely natural). When put another way, pressure translates to productivity.

And though the two procedures are unrelated, knowing how hard it is to wash your back deck using only a lower pressure water stream is an appropriate analogy for comparing and contrasting the two.

The diameter of the waterjet decreases as pressure rises. This signifies that it requires less water and abrasives, setting the stage for a quicker-moving water solution and sand particles, hence faster cutting.   

Generally speaking, if your equipment’s moving speed can keep up with the material you’re cutting, you should aim for higher pressure.
