Water jets are capable of cutting through a wide range of materials, including granite. The maximum thickness of granite that a water jet can cut will depend on a few factors, such as the power of the water jet and the type of granite being cut. In general, water jets can cut through granite up to about 4 inches (10 cm) thick. However, the actual thickness that a water jet can cut will depend on the specific machine being used, as well as the type and grade of the granite. Till now, we have test to cut the max. thickness up to 12 inches of granite. It’s important to note that the thickness of the granite is not the only factor that affects how well it can be cut by a water jet. Other factors, such as the shape and complexity of the design being cut, the speed of the cutting process, and the quality of the water jet machine, can all impact the final result. Additionally, water jet cutting can be a slower process compared to other cutting methods, so it may not be the best option for high-volume production of thick granite pieces.
