Water jet cutting is a manufacturing process that utilizes a high-pressure jet of water to cut through a wide range of materials. It has emerged as a popular alternative to traditional cutting methods, such as sawing, drilling, and milling. With the introduction of a stream of abrasive particles, water jet cutting can machine materials that are difficult or impossible to cut with other methods, such as metals, stone, ceramics, and composites. It can also cut through materials without creating a heat-affected zone, which is a common issue with other methods. Water jet cutting machines are equipped with computer numerical control (CNC) technology that allows for precise and accurate cuts, making it a versatile and efficient method for a variety of manufacturing applications. With the use of abrasives, water jet cutting can also be used for cutting hard materials, such as metal, to a high degree of precision.
