Guide to Waterjet Cutting and Its Benefits

The original use of the waterjet, which was invented in the 1950s, was to cut lumber from large trees. Today, because of advancements and improvements made on waterjet cutting methods, it can now be used for cutting any flat materials including stainless steel and aluminum.

High pressure stream of water is used for the waterjet method in order to cut or clean materials. The waterjet is usually connected to a high-pressure water pump which releases water from a nozzle which then cuts through the materials at high speed. To help in the process, they put additives in the form of abrasives.

Using waterjet cutting has many benefits including some of those given below.
The 10 Most Unanswered Questions about Cutting

A waterjet tool is a very powerful tool. Perhaps you don’t expect it to be that powerful but if you know that it can cut eight inch stainless steel plates, and 10 inches of aluminum plates, they you become a believer.
What No One Knows About Cutting

Other cutting methods generate high temperatures which is not ideal for cutting materials that are sensitive to it, and so the waterjet cutting is the preferred method. Waterjet cutting minimizes the effect of heat and allows metals to be cut without altering or damaging its surface because this method has no heat-affected zone.

Another benefit of waterjet cutting is that its cut is very precise. The accuracy of waterjet cutting is 0.13mm and its repeatability is 0.03 mm. Using waterjet method for cutting is not only precise especially for steel and aluminum, it also provides a burr-free finish. And this eliminates secondary surface finishing in most cases, which saves you a lot of money.

You can also benefit from the speed of waterjet cutting. If you have a project done using waterjet, you can have a fast and efficient work done. The reason for the speed is because it is easy to set-up, it is a very fast cutting process compared to other methods, and you don’t need to re-cut because of its precision.

Waterjet cutting is good for the environment. This is because there is no hazardous waste produced when using it to cut things. It also prevents unnecessary waste of resources since large pieces of reusable scrap material can be cut off which is not possible using traditional cutting methods.

When using waterjet cutting for stainless steel or aluminum, there are more environmental advantages. Little water is used in waterjet cutting. It turns out to be one half to one gallon of water used per minute. The amount depends on the cutting head orifice size.

IF you have a closed looped system, the water used can also be recycled. The waste water is filtered and disposed through a drain which is clean enough to reuse.

The removal of airborne dust particles, smoke, fumes, and contaminants from cutting materials is another benefit of waterjet cutting. This greatly improves the working environment and reduces problems arising from the machine operator’s exposure.The working environment is then improved greatly and the machine operator will have reduced problems from exposure.
