Water jet cutting is the process of applying a jet of water or a jet of water combined with an abrasive substance (such as garnet or sand) with intense pressure to a highly durable material such as metal. When ejected at high velocity, water or water combined with an abrasive substance is capable of rendering precise cuts to a variety of heavy-duty materials. The water is jetted out at roughly three times the speed of sound. It is possible for water jets to cut steel that is up to 12 inches in thickness.
Water jet cutting can be thought of as a concentrated technique of water erosion. Its ability to cut durable materials has led it to be used in various different industries. Water jet cutting can be used to cut the following materials:
The above materials are applicable in many industries, making water jet cutting a widely used method.
The building and renovation industries rely heavily upon the use of water jet cutting. Commonly used materials in these industries, such as granite, marble and stone require this advanced technique in order to render precise, smooth edges. As these materials are costly, it is important that they be cut with care, so as to avoid costly mistakes.
The majority of water jet cutting systems are developed with the same characteristics. Each system contains a pump that will increase the pressure of the water according to the thickness of the material to be cut.
Once the pressure is adjusted accordingly , the material is set down and the stream of water is controlled robotically in order to render precise cuts and shapes. The actual stream of the water jet is narrow as compared to other heavy-duty cutting systems, making water jet cutting a popular choice for those who require specific shapes and designs.
While some may assume that the precision and intricacy required by water jet cutting would make it an expensive cutting method, it is actually cheaper than more traditional methods. In addition, no thermal stress can be noticed on the material after using water jet cutting. Cutting methods that require high heat, such as laser cutting methods, can sometimes cause edges to warp or become deformed.
Water jet cutting is able to cut thicker materials compared to many other cutting methods. Aside from cost and cutting capabilities, there are a variety of other benefits to using water jet cutting. It is considered to be an ecologically sound process as it does not produce hazardous waste. In turn waste disposal is minimal and safe.
Water jet cutting is capable of rendering less wasted material than others, meaning that more expensive material can be used efficiently. Furthermore, used water from one project can be reused again. The abrasive that is found in the water is also not a toxic substance.
