Benefits of Waterjet Cutting for Industrial Sectors
The concept of waterjet cutting has been around since the 1950’s when it was first conceptualized by Dr. Norman Franz. 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. Abrasives may also be added to help in cutting specific materials.
While waterjet cutting can be used for a number of different materials, there are at least five benefits for cutting aluminum and stainless steel.
1. The Waterjets Capacity. 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. No Heat is Necessary Since waterjets don’t generate heat when cutting materials, it is the preferred method for those materials sensitive to rising temperatures. Most methods of cutting materials will damage or alter the surface but the no heat-affected zone (HAZ) prevents this from occurring when using a waterjet.
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″. Waterjets provides a burr-free finish. The burr-free finish eliminates the necessity of a secondary finishing process, which saves money.
4.Speed There isn’t much labor needed to use the waterjet. The entire cutting process is significantly faster than other cutting methods. The waterjets are so precise that re-cutting is avoided.
5. Waterjets are environmentally friendly The waterjet cutting process is considered to be one of the more environmentally friendly of all the methods. No hazardous waste is produce during the process of cutting materials. Waterjets also prevent unnecessary waste that occurs during traditional cutting methods.
There are several environmental advantages when choosing waterjets to cut your materials. Waterjets use very little water. Almost one half to one gallon of water will be used per minute, depending on the cutting head orifice size. 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. A safer work environment is created. Waterjets eliminate airborne dust particles, smoke, fumes, and contaminants from cutting materials. Machinist exposure is reduced as well as any problems from bystander exposure through the use of waterjet cutting, which improves the work environment.
