Many different combination materials, especially reinforced plastics, can be cut with a waterjet. Carbon fiber-reinforced plastics can be cut quickly and cleanly, making waterjets a great addition to the fabrication of aerospace components and racecars. Using a waterjet will ensure that there is no tool clogging or wear, no need to change tooling, no melting, and no hazardous fumes. When cutting glass-reinforced plastics, fiberglass can be cut quickly and cleanly. By submerging the material during the cutting process, you can ensure that no hazardous dust or fumes will be produced.
Cutting steel is one of the most common uses of waterjet cutting. Waterjets can cut all grades of steel, producing a smooth edge without burn marks, cracking, excess burr, or many other issues associated with heat-based cutting. Using heat methods can weaken the integrity of the part, making waterjet cutting more favorable. This lack of a heat affected zone makes waterjet cutting a great option for fabrication of food processing and handling parts as well as aerospace materials. Waterjets can even be used to cut hardened tool steel. It can be cut in a fully hardened state without any risk of change to the metal properties.
Metals other than steel can also be cut with a waterjet. Aluminum is probably the most common metal cut with a waterjet. Alloys are often difficult to machine without heat or distortion, but alloys of all types can be cut accurately with a waterjet. Waterjet cutting is a great option to cut titanium because its precision will reduce the amount of waste material. This reduction of waste is especially important in expensive metals like titanium. A waterjet is also a good option for more reflective metals like copper, as there will be no reflectivity issue like there is for laser cutting.
Beyond composites and metals, most materials can be cut using a waterjet. Stone and concrete can be cut with a waterjet, making the tool ideal for granite countertops, architectural features, and marble flooring. Ceramics can also be cut using a water jet, as long is their hardness is less than an 8.5 on the Mohs scale. Softer materials such as rubber and wood can even be cut with a waterjet, using the water-only nozzle without the abrasive.
At CAMM Metals, we use waterjets in several different ways. First, we use them to cut all of our flat sheet metal and plate to feed the fabrication work we do. The precision from the waterjet is just as good as laser cutting and better than plasma cutting. Second, we use these machines to process thick plates and pre-cut shapes and blanks for our CNC Machining centers. Third, we offer water jet cutting as a service to customers who do not have this capability. We can use our material or you can drop ship us your material and generally within 3 days your parts will be cut and ready to go. Lastly, we can cut round and rectangular tubes and pipes.
