Most machines accomplish this by first running the water through a high pressure pump. In order to cut harder materials like metals or granite, an abrasive material is mixed in the water. Water Jet Machining Working Principle: Water jet machine widely used for cutting plastic, cloth, rubber, paper and leather, because of the lack of heat it produces kerf very narrow, and if set up correctly produce very smooth edges no scraps or burrs Water jet machine is a very clean job with no dust or noise, odor and very little, in fact, the health and safety and environmental impact is minimal, almost. It is useful for machining heat sensitive material. Nozzle converts some pressure energy of water into kinetic energy. The principles of abrasive water jet cutting are similar to pure water jet cutting, but once the stream has passed through the orifice it enters a carbide nozzle. It uses water jet working as a tool to cut the metal. On this channel you can get education and knowledge for general issues and topics This high pressure water now sends through tubing system to nozzle. There is a nozzle at the … Water Jet cutting uses an ultra-high pressure stream of water to carry an abrasive grit. Subscribe our channel for more interesting articles. There are two types of water jet machines they are. Generally Aluminium oxide, Silicon carbide etc. Working medium is water, highly available in nature. It cannot used for machining material which degrade in presence of water. Tubes are used to supply high pressure water to the nozzle for further cutting process. Abrasive Jet Machining could able to remove metals due to the erosion of high-speed abrasive particles. General abrasive particles are garnet,silicon etc.This can cut different types of metals and used in different industries. To generate the required high-pressure water jet, a high-pressure pump brings the water to a pressure of up to several thousand bar and directs it to the cutting head. In this process, a high speed well concentrated water jet is used to cut the metal. Now this high pressure water enters into nozzle. Water jet machining (WJM) is cne ('f such processes of material removal. Atom This chapter provides an understanding of AWJM process. It provide flexible movement and does not allow any significant loses. It is environment friendly because it does not form any dust particle and used water as cutting fluid. This induces a stress on the workpiece. The working of water jet machining can be summarize as follow. Flow regulators are used to regulate the flow according to cutting requirement. Water Jet Machining – Working Principle, Advantages and Disadvantages with Application; Laser Beam Machining – Main Parts, Principle, Working with Application; At cathode the hydrogen ions takes electrons and gets converted into hydrogen gas.
