Understanding Waterjet

The Benefits of Waterjet Cutting Methods

Since the 1950s, waterjet cutting has been around, developed as a way 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.

In order to cut or clean materials, a waterjet uses a high pressure stream of water. 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. Putting additives in the form of abrasives helps in the cutting process.

Here are some of the benefits of using waterjet cutting for cutting different types of flat materials.

One of the benefits of using waterjets is that it is very powerful. If you don’t expect waterjet to be that powerful just imagine that it can cut through eight inches of stainless steel plate and 10 inches of aluminum plates.

Waterjet cutting is the best method to cut materials that are sensitive to high temperatures such as that generated by using other methods. This is because there is no heat-affected zone and so it minimizes the effect of heat which allows metal to be cut without altering or damaging the surface of the material being cut.

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 of cutting gives you a burr-free finish aside from its precision cutting especially for steel and aluminum. Since it almost eliminates secondary surface finishing, it will save you a lot of money.

Waterjet cutting is cutting with great speed. Projects using waterjet method can benefit from its speed and efficiency. The reason for this is that it can easily be set up, the cutting process is faster than any other methods, and re-cutting is avoided because waterjet cutting is very precise.

Waterjet is also considered green technology. When the method of waterjet cutting is used, there are no hazardous waste materials produced. With waterjet cutting you can cut large pieces of reusable scrap material so it prevents unnecessary waste of resources which cannot be done with traditional cutting methods.

There are more environmental advantages when you use waterjet cutting for your steel or aluminum. The amount of water used in waterjet cutting is very little. The per minute use of water for waterjet cutting is only one half to one gallon of water. The size of the cutting head orifice determines the amount of water used.

Recycling water is possible if you use a closed looped system. Waste water is often clean enough to filter and dispose of through a drain.

Another advantage of waterjet cutting is that it removes airborne dust particles, smoke, fumes, and contaminants from cutting materials. 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.
