On Cutting: My Rationale Explained

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. While originally utilized to help engineers cut lumber, waterjet cutting is now an effective method for cutting almost any flat material, including stainless steel and aluminum.

Waterjet cutting uses high-pressure water streams to cut or clean objects and materials. 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 several different advantages to using water when cutting stainless steel or aluminum.

1. The Ability of Waterjets to cut through almost anything. Waterjets are extremely powerful and have the ability to cut through almost any thickness of aluminum and stainless steel.

2. Using waterjets doesn’t mean heat is required. Since waterjets don’t generate heat when cutting materials, it is the preferred method for those materials sensitive to rising temperatures. The no heat-affected zone (HAZ) minimizes the effects of heat, which allows for metal to be cut without damaging the surface.

3. Waterjets exhibit the highest level of precision of cutting methods The precision of waterjets is high enough to state that the accuracy is 0.005″ and when repeated stands at 0.001″. 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.Waterjets are an extremely fast and efficient process for cutting projects 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. Re-cutting isn’t necessary because waterjets have such precision with cutting materials.

5. Waterjets are environmentally friendly Waterjet cutting is one of the only environmentally sound process. During the process of cutting materials with the waterjet, there are no byproducts produced. Considering the large pieces of recyclable scrap metal or material can be cut, the waterjets prevent waste that occurs when using other cutting methods.

6. There are a number of environmental benefits to using waterjets to cut stainless steel and aluminum. 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. The water that is use can be recycled by using a closed-looped system. Often, the waste water can be poured into the drain due to its being cleaned through the closed-looped system.

7. The waterjets create a safer work environment Waterjets eliminate airborne dust particles, smoke, fumes, and contaminants from cutting materials. This greatly improves the work environment and reduces problems arising from the machine operator’s exposure.
