Water jet cutters use high-velocity jets of water to cut a wide variety of materials, including thick and dense ones. They are environmentally friendly, precise, and do not create areas of weakness in the materials they cut. Safety precautions must be observed when using them.
A water jet cutter is a device designed to cut with the use of a jet of water. Waterjet cutters can handle a wide variety of materials and have some distinct advantages over other types of cutting tools. Several companies manufacture water jet cutters that can be purchased or leased, and some companies use these cutters in industrial settings, for tasks such as fabricating custom parts.
The first versions of the waterjet cutter were developed in the 1950s and worked by generating a high-velocity jet of water that was also highly pressurized. In the 1970s, innovators realized that the effectiveness of a waterjet cutter could be greatly increased by adding an abrasive material such as powdered garnet to the stream of water. Modern waterjet cutters can machine very thick and very dense materials, such as brick.
In essence, a water jet cutter is like erosion on steroids, with the ability to very precisely direct the direction of erosion. These cutters can be used for a variety of precision cutting tasks that might be difficult with other devices. They are also more environmentally friendly, because they do not generate pollution, and many models are designed to recycle water, including water mixed with abrasives, which reduces waste and cuts operating costs.
For manufacturers, the waterjet cutter is also useful because it doesn’t create areas of weakness in the materials it cuts. Other types of cutters can generate areas around the cut that have been damaged by heat, generated by the friction created during the cutting process. A waterjet cutter is cold and inert, preventing stress on the material being cut. It also generates no dust and is a highly versatile cutting option that can be easily adjusted by swapping the cutter head.
These cutters are available in a range of sizes designed for various applications. Water jet cutters require a pressurized source, as the water that comes out of the faucet is not pressurized enough, so most are designed to connect to compressors. It is also important to observe safety precautions such as wearing safety glasses when using the cutter, never pointing the cutter at anyone even if the intensity of the jet decreases rapidly the further you get from the source, and wearing protective clothing such as boots and gloves when handling the waterjet cutter.
