In some cases, you likewise accomplish not discover the statement principles of abrasive water jet machining that you are looking for. It is used to machining or cutting reinforced plastic. A pump sucks water from water reservoir and send it to intensifier. of nozzle – (0.07-0.5mm) Working principle 7. which is mixed in high-pressure water to increases the cutting property of the fluid. It causes material removal and separates the material. In the same way the iron atoms comes out from the anode (w/p) as Fe++ ions. For machining soft materials, water jet machining is used and for machining hard materials, abrasive water jet machining is used. This is the same as water jet machining, Water from the tank is supplied to the intensifier by the help of a hydraulic pump, their water increases to high pressure.this high-pressure water used to pass through orifice after getting into orifice abrasive particles are used to mix with water and further sent to the valve to supply required quantity into the nozzle, this increases the velocity of abrasive water and makes to strike the metal for cutting/removing. Working medium is water, highly available in nature. 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.
