Waterjet cutting is a highly precise and versatile cutting process used in various industries, including manufacturing, aerospace, automotive, architecture, electronics, and fabrication. It utilizes a high-pressure stream of water mixed with abrasives to cut through a wide range of materials.
The process involves directing water through a narrow nozzle at pressures ranging from 30,000 to 90,000 psi. For cutting softer materials, the water stream alone may suffice. However, when dealing with harder materials like metals, stone, glass, or composites, abrasive particles like garnet (sand) are added to enhance the cutting power.
By combining high-pressure water with abrasives, waterjet cutting generates a force capable of slicing through materials with exceptional precision. Computer numerical control (CNC) technology is often employed to precisely control the waterjet, allowing for the effortless cutting of intricate and complex shapes. Notably, the cutting process is non-thermal, meaning it doesn’t generate heat, making it ideal for heat-sensitive materials.
Waterjet cutting boasts several advantages over alternative cutting methods. It is an eco-friendly process that doesn’t produce harmful fumes, gases, or dust. Its versatility enables the cutting of diverse materials, including metals, plastics, stone, ceramics, and composites, while maintaining high precision and minimizing material wastage. Moreover, it doesn’t create a heat-affected zone (HAZ) along the cut edge, ensuring the preservation of material properties.
In manufacturing for example, waterjet cutting finds application in precision cutting, prototyping, inlay and assembly, gasket manufacturing, decorative cutting, automotive part production, aerospace component fabrication, electronics manufacturing, and more. Its ability to deliver precise cuts and intricate designs with remarkable accuracy makes it an invaluable tool across various industries.
