In an informative guide authored by Simon Jones titled “Waterjet Cutting: An Essential Guide,” we dive into the world of hydro-abrasive waterjet cutting and explore its significance in modern machining. This cutting-edge technology has undergone a remarkable evolution and is now recognized as one of the most efficient machining methods.
The Versatility of Waterjet Cutting One of the standout features of waterjet cutting is the absence of a heat-affected zone (HAZ). With small cutting widths and omni-directional cutting capabilities, it can precisely machine almost any material. The result is a superior product finish that often requires little to no secondary processing.
Beyond its precision, waterjet cutting is also environmentally friendly, producing no dust, chippings, or gas that other cutting methods generate. There’s no need to change tool heads, blades, or lubricants for different materials, which significantly reduces machining time. Moreover, this method generates less waste, allowing for more intricate and diverse designs.
The Mechanics of Waterjet Cutting Waterjet cutting is commonly employed in fabricating machine parts, as well as in mining and aerospace for cutting, shaping, and reaming. It’s highly accurate, with a tolerance of 0.005 inches and a repeatability of 0.001 inches throughout the process. Waterjet cutting machines utilize high-pressure water pumps that supply water at 60,000 Psi to twin cutting heads. These heads force pressurized water through a small opening lined with diamond, ruby, or sapphire, with an abrasive material added to cut tougher metals. The jet, moving at about three times the speed of sound, is directed onto the material.
