Benefits of Waterjet Cutting for Industrial Sectors

Dr. Norman Franz discovered waterjet cutting in the 1950’s when he was seeking an alternative method to cut lumber. Not only is waterjet cutting used to help lumber companies, it has improved and been proven effective in the stainless steel and aluminum industries.

Waterjets use a simple process of high pressure streamed water which allows for the materials to be cut or cleaned. In order for the waterjet to be effective for cutting materials, the cutter is attached to a high-pressure water pump where the water is ejected from the nozzle. In order to help the cutting process, abrasives may be added.

There are many different benefits to using waterjet cutting for stainless steel or aluminum sheets.

1. The Power of Waterjets. At first glance, many do not expect water to be a powerful cutting tool but wateriest have the capacity to cut through eight-inch stainless steel plates and ten-inch aluminum plates.

2. Waterjets do not require heat Waterjet cutting is the preferred method for those materials that are sensitive to higher temperatures that are often created when using alternative methods. The no heat-affected zone (HAZ) minimizes the effects of heat, which allows for metal to be cut without damaging the surface.

3. There is a significantly high level of precision Waterjets are very precise cutting tools, as they are capable of attaining an accuracy of 0.005″ (0.13 mm), and repeatability of 0.001″ (0.03 mm). Next to having an extremely high level of precision, the waterjets also produce a burr-free finish. The secondary surface finishing process can be spared in most cases and helps save money.

4.Speed There isn’t much labor needed to use the waterjet. Waterjets have the fastest cutting time out of all the different ways for cutting materials. The waterjets are so precise that re-cutting is avoided.

5. Using waterjet cutting allows for the materials to be cut in an environmentally sound manner. Waterjets are classified as green technology. Waterjet cutting does not produce hazardous byproducts. The use of waterjets prevents wasteful cutting from occurring, since the large pieces of reusable scrap material can be cut off.

When using waterjets to cut aluminum or stainless steel, there are a plethora of environmental advantages. Not a lot of water is necessary to use the waterjet. For each minute the waterjet is in use, approximately one half to one gallon of water will be used dependent upon the size of the cutting head orifice. By using a closed-looped system, the water used can be reused. Waste water is often clean enough to filter and dispose of through a drain.

7. The waterjets create a safer work environment By using waterject cutting, smoke, fumes, dust particles, and contaminants can be avoided by workers. Machinist exposure is reduced as well as any problems from bystander exposure through the use of waterjet cutting, which improves the work environment.
