The 4 Most Unanswered Questions about Waterjets

Why Invest in Waterjet Cutting Services

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.

Waterjet cutting uses high-pressure water streams to cut or clean objects and materials. The cutter itself can be connected to a water pump that ejects high-pressure water from a nozzle thus cutting the material with high-speed water. 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. 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. Waterjet cutting has a no heat-affected zone (HAZ) that prevents alterations and damage to the surface of the materials being cut.

3. Waterjets exhibit the highest level of precision of cutting methods 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). Waterjets provides a burr-free finish. The burr-free finish eliminates the necessity of a secondary finishing process, which saves money.

4. Waterjets allows for projects to be completed in a quick and efficient manner. The initial set-up time is small. The cutting process is quicker than other methods that may be utilized for cutting materials. Re-cutting isn’t necessary because waterjets have such precision with cutting materials.

5. Using waterjet cutting allows for the materials to be cut in an environmentally sound manner. The waterjet cutting process is considered to be one of the more environmentally friendly of all the methods. 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. The waterjet does not use a significant amount of water. 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. Using waterjet cutting allows for a safer work environment to be created. Waterjets eliminate airborne dust particles, smoke, fumes, and contaminants from cutting materials. The elimination of exposure to these allows for improvements in the work environment and reduces problems that may arise from machinist exposure.
