A waterjet cutting machine is an industrial cutting system that uses a high-pressure stream of water to cut different materials. For harder materials such as metal, stone, or ceramic, the water is often mixed with fine abrasive particles to improve cutting performance. Unlike many traditional cutting methods, the process does not rely on heat, making it suitable for materials that can be affected by high temperatures.
The idea of using pressurized water for cutting has developed over several decades. Early systems were mainly used for softer materials such as paper and rubber. Advances in pump technology and abrasive cutting methods later expanded its use across manufacturing, construction, aerospace, automotive production, and metal fabrication.
Today, waterjet cutting machines are valued for their ability to produce detailed shapes while reducing heat-related material changes. They can process a wide range of materials with consistent accuracy, making them an important part of modern industrial manufacturing.
